Discretionary Budget Authority by Subfunction: An Overview

Summary
This report provides a graphical overview of historical trends in discretionary budget authority
(BA) from FY1976 through FY2012, preliminary estimates for FY2013 spending, and the levels
consistent with the President’s proposals for FY2014 through FY2018 using data from President
Obama’s FY2014 budget submission that was released on April 10, 2013. Spending caps and
budget enforcement mechanisms established in the Budget Control Act of 2011 (P.L. 112-25;
BCA) strongly affected the FY2013 and FY2014 budget cycles. Congress modified BCA caps at
the beginning of January 2013 to scale down the size of discretionary spending reductions for
FY2013 and in December 2013 to scale down the size of reductions slated for FY2014 and
FY2015.
As the 113th Congress prepares to consider funding levels for FY2015 and beyond, past spending
trends may help frame policy discussions. For example, rapid growth in national defense and
other security spending in the past decade has played an important role in fiscal discussions. The
American Recovery and Reinvestment Act of 2009 (P.L. 111-5; ARRA) funded sharp increases
in spending on education, energy, and other areas. Since FY2010, however, base defense
discretionary spending has essentially been held flat and non-defense discretionary spending has
been reduced significantly. The base defense budget excludes war funding (Overseas
Contingency Operations/Global War on Terror). This report provides a starting point for
discussions about spending trends. Other CRS products analyze spending trends in specific
functional areas.
Functional categories (e.g., national defense, agriculture, etc.) provide a means to compare federal
funding for activities within broad policy areas that often cut across several federal agencies.
Subfunction categories provide a finer division of funding levels within narrower policy areas.
Budget function categories are used within the budget resolution and for other purposes, such as
possible program cuts and tax expenditures. Three functions are omitted: (1) allowances, which
contain items reflecting technical budget adjustments; (2) net interest, which by its nature is not
discretionary spending; and (3) undistributed offsetting receipts, which are treated for federal
budgetary purposes as negative budget authority.
Spending in this report is measured and illustrated in terms of discretionary budget authority as a
percentage of gross domestic product (GDP). Measuring spending as a percentage of GDP in
effect controls for inflation and population increases. A flat line on such graphs indicates that
spending in that category has been increasing at the same rate as overall economic growth.
Graphs were updated to reflect the revisions to national income accounts released by the
Department of Commerce’s Bureau of Economic Analysis in July 2013.
Discretionary spending is provided and controlled through appropriations acts, which provide
budget authority to federal agencies to fund many of the activities commonly associated with
such federal government functions as running executive branch agencies, congressional offices
and agencies, and international operations of the government. Essentially all spending on federal
wages and salaries is discretionary. Program administration costs for entitlement programs such
as Social Security are generally funded by discretionary spending, while mandatory spending—
not shown in figures presented in this report—generally funds the benefits provided through those
programs. For some federal agencies, such as the Departments of Veterans Affairs and
Transportation, the division of expenditures into discretionary and mandatory categories can be
complex. This report will be updated for the FY2015 budget submission.

Discretionary Budget Authority by Subfunction: An Overview

Introduction
This report presents figures showing trends in discretionary budget authority as a percentage of
GDP by subfunction within each of 17 budget function categories, using data from President
Obama’s FY2014 budget submission.1 This report provides a graphical overview of historical
trends in discretionary budget authority from FY1976 through FY2012, preliminary estimates for
FY2013 spending, and the levels consistent with the President’s proposals for FY2014 through
FY2018.2
Discretionary spending is provided and controlled through appropriations acts. These acts fund
many of the activities commonly associated with federal government functions, such as running
executive branch agencies, congressional offices and agencies, and international operations of the
government.3 Thus, the figures showing trends in discretionary budget authority presented below
do not reflect the much larger expenditures on program benefits supported by mandatory
spending. For some departments, such as Transportation, the division of expenditures into
discretionary and mandatory categories can be complex.
Discretionary spending in this report is measured in terms of budget authority. Budget authority
for an agency has been compared to having funds in a checking account. Funds are available,
subject to congressional restrictions, and can be used to enter into obligations such as contracts or
hiring personnel. Outlays occur when the U.S. Treasury disburses funds to honor those
obligations. Spending in this report is shown as a percentage of GDP to control for the effects of
inflation, population growth, and growth in per capita income. A flat line on such graphs indicates
that spending in that category is increasing at the same rate as overall economic growth. Graphs
were updated to reflect the revisions to national income accounts released by the Department of
Commerce’s Bureau of Economic Analysis in July 2013.4 In general, the revised GDP series
showed somewhat higher levels of national income and thus slightly reduced government
spending as a share of GDP.

1 The President’s FY2014 budget was released on April 10, 2013, and is available at http://www.whitehouse.gov/omb/
budget/.
2 The start of the federal fiscal year was changed from July 1 to October 1 in 1976 to accommodate changes in the
congressional budget process. The figures omit data for the transition quarter (July 1 to September 30, 1976). It appears
that FY2013 data omit the effects related to the March 1, 2013, sequestration triggered by the absence of a Joint Select
Committee on Deficit Reduction (Super Committee) plan and final action on FY2013 appropriations. See FY2014
Budget of the U.S. Government
, Summary Table S-4, note 2.

Andrew Austin.
4 The Bureau of Economic Analysis (BEA) has provided extensive technical information on its revision of national
income and product accounts (NIPA), which is available here: http://bea.gov/national/an1.htm#2013comprehensive.
The revision, according to BEA, included several major improvements to the accounts, including expanded
capitalization of intellectual property products and a change to accrual accounting for defined benefit pension plans.
The revision covered estimates from 1929 through the first quarter of 2013. For 2002–2012, the revised estimate of
average annual economic growth is 1.8%, or 0.2 percentage points higher than previously published estimates. For
years 2009–2012, the revised estimate of annual economic growth is 2.4%, or 0.3 percentage points higher than
previously published estimates. For details see Stephanie H. McCulla, Alyssa E. Holdren, and Shelly Smith, “Improved
Estimates of the National Income and Product Accounts: Results of the 2013 Comprehensive Revision,” Survey of

Discretionary Budget Authority by Subfunction: An Overview

Discussions about the appropriate levels of spending for various policy objectives of the federal
government have played an important role in congressional deliberations over funding measures
in the last several years and are expected to play a central role as Congress considers decisions
affecting the FY2014 budget.5 As the 113th Congress prepares to consider funding levels for
FY2015 and beyond, past spending trends may prove useful in framing policy discussions. For
example, rapid growth in national defense and other security spending in the past decade has
played an important role in fiscal discussions. The sharp increases in federal spending on
education, energy, and other areas funded by the American Recovery and Reinvestment Act of
2009 (P.L. 111-5; ARRA) have also played a significant role in recent budget debates.
Discretionary spending caps and budget enforcement mechanisms established in the Budget
Control Act of 2011 (P.L. 112-25; BCA) framed policy discussions during the FY2014 budget
cycle.6 The BCA was signed into law on August 2, 2011, after months of intense negotiations
over alternative plans to reduce the deficit and raise the debt limit. In December 2013, the
Bipartisan Budget Act (BBA; H.J.Res. 59; P.L. 113-67) modified BCA limits for FY2014 and
FY2015. The Consolidated Appropriations Act, 2014 (H.R. 3547; P.L. 113-76), enacted on
January 17, 2014, provides funding within those limits for the remainder of FY2014. The BBA
also provides top-line defense and non-defense discretionary spending limits for FY2015.
Office of Management and Budget and Federal Budget Data
Figures in this report are based on the Office of Management and Budget (OMB) Public Budget
Database accompanying the FY2014 budget release.7 Table 5.1 in the Historical Tables volume of
the FY2014 budget reports budget authority by function and subfunction, but does not provide a
breakdown by discretionary and mandatory subcomponents.8
OMB is the official custodian of historical federal budget data. While OMB has attempted to
make these data consistent, changes in government accounting standards and agency
reorganizations, among other changes, may raise difficulties in comparing data from different
fiscal years. For example, the Department of Homeland Security (DHS) was created in 2002 from
22 existing federal agencies or entities.9 OMB used historical budget data for those agencies or
entities to calculate retrospective estimates for DHS.
Budget data in OMB documents may differ from other budget data for various reasons, although
differences in historical data are typically small. For example, appropriations budget documents
often reflect scorekeeping adjustments. Budget data issued at a later date may include revisions
absent from earlier data. In some cases, detailed appropriations data may differ from OMB data,
which sometimes do not reflect certain relatively small zero-balance transfers among funds.

Discretionary Budget Authority by Subfunction: An Overview

Differences may also reflect technical differences or different interpretations of federal budget
concepts.
Background on Functional Categories
Functional categories provide a means to compare federal funding for activities within broad
policy areas that often cut across several federal agencies.10 Because various federal agencies may
have closely related or overlapping responsibilities, and because some agencies have
responsibilities in diverse policy areas, budget data divided along functional categories can
provide a useful view of federal activities in support of specific national purposes. Superfunction
categories, which provide a higher level division of federal activities, are
• National defense,
• Human resources,
• Physical resources, and
• Other functions.
Net interest, Allowances, and Undistributed offsetting receipts could also be considered as
separate categories. Superfunction categories for national defense, net interest, allowances, and
undistributed offsetting receipts coincide with function categories. Trends in net interest are
excluded as federal interest expenditures have been automatically appropriated since 1847.
Allowances, which contain items reflecting technical budget adjustments, and undistributed
offsetting receipts, are also excluded. Allowances in FY2014 include unspecified cuts to comply
with BCA spending caps, future disaster funding costs, and war funding (Overseas Contingency
Operations/OCO; Global War on Terror/GWOT) for years after FY2014.11
Budget function categories, grouped by superfunctions, are shown in Table 1.
Subfunction categories provide a finer division of funding levels within narrower policy
areas. Subsequent figures follow the ordering of functions in Table 1.

10 For further background on functional categories, see CRS Report 98-280, Functional Categories of the Federal
Budget
, by Bill Heniff Jr.
11 The allowance for future disaster costs is not included in calculations underlying graphs in order to conform with
published data aggregates. Allowances that reflect enforcement of BCA discretionary spending limits are not included,
as they are not disaggregated by function.

Discretionary Spending in the FY2014 Budget
Budget discussions for FY2014 in large part were framed by the BCA.12 Spending limitations on
discretionary spending imposed by the BCA had been slated to make sharp reductions in defense
and non-defense spending in FY2013 and FY2014.13 Congress has modified provisions of the
BCA, however, to lessen the stringency of those reductions. Those modifications are discussed in
more detail below, after a short explanation of relevant BCA caps.
Caps Lowered in Absence of Super Committee Plan
When the Joint Select Committee on Deficit Reduction (JSC), known as the “Super Committee,”
did not present a plan to achieve at least $1.2 trillion in deficit reduction over FY2013-FY2021,
the original BCA caps were then superseded by revised caps, which imposed separate limits on
base defense (budget function 050) and non-defense spending. Base defense funding covers
normal costs of national defense, while war costs are not subject to BCA caps.14 The sum of total
discretionary spending under the original and revised caps was the same. Further reductions of
$109 billion for each year from the revised cap levels, split between defense and non-defense,
were slated to occur in each year from FY2013 through FY2021. In FY2013 savings were to be
made through sequestration, and in years FY2014-FY2021 savings are slated to occur through a
lowering of the discretionary spending caps. Those lowered caps, along with interest savings and
an ongoing sequester of non-exempt mandatory spending, were designed to capture the $1.2
trillion in budget savings in the absence of a Super Committee plan.

12 Budget Control Act of 2011 (P.L. 112-25; BCA).
13 For a more complete description of recent budget legislation, see CRS Report RL34424, Trends in Discretionary
Spending

14 War costs, however, are not exempt from sequestration. Those costs are described as Overseas Contingency
Operations (OCO) in budget documents.

Discretionary Budget Authority by Subfunction: An Overview

Fiscal Cliff Deal and the American Taxpayer Relief Act
The American Taxpayer Relief Act (H.R. 8; P.L. 112-240; ATRA) delayed the Super Committee
sequester by two months, from January 2, 2013, to March 1, 2013.15 In addition, the size of the
FY2013 sequestration cuts was reduced from $109 billion to $85 billion.16 Discretionary caps on
FY2014 defense and non-defense funding, as part of an offset for that reduction, were reduced by
$4 billion each. Thus, the revised cap on FY2014 defense funding was reduced from $556 billion
to $552 billion. The revised cap on FY2014 non-defense funding was reduced from $510 billion
to $506 billion. Defense and non-defense spending are slated for reductions of $54.7 billion each,
allocated between discretionary and mandatory spending. Because non-exempt defense
mandatory spending is relatively small, most of the defense reduction would be borne by base
defense discretionary spending via a lowered cap. According to preliminary OMB estimates, the
lowered FY2014 cap for base defense discretionary BA will be $468.8 billion.17
On the non-defense side for FY2014, Medicare patient care expenses and other non-exempt
mandatory spending were estimated to bear $18.1 billion of the $54.7 billion reduction through a
sequester, according to OMB. The remaining $36.6 billion would be borne by non-defense
discretionary spending via a lowering of its revised cap ($506 billion) to $469.4 billion.18
The FY2013 Super Committee sequester, implemented on March 1, 2013, reduced Medicare
mandatory patient care spending by $11.3 billion and other non-defense mandatory spending by
$5.4 billion, while non-defense discretionary BA was reduced by $25.8 billion.19 The reduction
that had been slated for non-defense in FY2014 was larger than the FY2013 reductions for two
reasons. First, the non-defense sequester was half of $85 billion, rather than the half of $109
billion sequester slated for FY2014. Second, the reduction of Medicare patient care spending is
limited to 2%, which implies that changes in the size of non-defense reductions will be chiefly
reflected in changes in funding of discretionary programs and non-exempt non-Medicare
mandatory programs.20
FY2014 Administration Proposals Regarding Caps
The Administration in its FY2014 budget, submitted on April 10, 2013, proposed a set of
modifications of BCA caps on discretionary spending. The Administration proposed that FY2014

15 For details, see CRS Report R42949, The American Taxpayer Relief Act of 2012: Modifications to the Budget
Enforcement Procedures in the Budget Control Act
, by Bill Heniff Jr. ATRA was sent to the President on January 1,
2013, and enacted the following day.
16 Thus the size of the FY2013 sequester was reduced by $24 billion.

18 Ibid., Table 3, p. 15.
19 The BCA specifies sequester reductions in mandatory spending in terms of outlays. For discretionary spending, the
Super Committee sequester canceled budget authority for FY2013. Discretionary spending reductions are slated to be
implemented through lowered caps on budget authority from FY2014 through FY2021. See OMB, Report to the
Congress on the Joint Committee Sequestration for Fiscal Year 2013
, March 1, 2013; available at

considered payment in full.

Discretionary Budget Authority by Subfunction: An Overview

spending limits be set at revised cap levels (i.e., $552 billion for defense and $506 billion for non-
defense) rather than lowered cap levels (i.e., $498.1 billion for defense and $469.4 billion for
non-defense), which would have allowed higher levels of discretionary spending while the
economy is still recovering from a major recession. Spending limits for the second half of the
FY2013-FY2021 budget window, in the Administration’s proposals, would have been lowered by
$60 billion apiece for defense and non-defense. In addition, discretionary caps would have been
extended to FY2022 and FY2023.
The Administration estimated that those spending cap modifications would reduce discretionary
spending by $202 billion over the FY2014-FY2023.21 Thus, projected discretionary spending for
FY2014-FY2018 shown in the figures below, which presume the President’s budgetary proposals
are adopted, reflects an assumption that BCA constraints on discretionary spending would be
loosened in FY2014 and tightened later on starting in FY2017. The Administration’s FY2014
budget plan also includes $260 billion in unspecified reductions in discretionary spending, mostly
slated for FY2015 through FY2023.22 If those reductions were carried out, discretionary spending
levels would have been less than that shown in figures below.
The Bipartisan Budget Act of 2013
During the FY2014 budget cycle, the House and Senate responded to the budgetary challenges
presented by BCA caps in different ways. Just before the August 2013 recess, the gap between
House and Senate totals for FY2014 discretionary spending stood at about $90 billion. The House
Appropriations Committee set suballocations for its subcommittees that totaled $973.1 billion,
slightly above total discretionary spending at BCA lowered caps levels ($967.5 billion) for
FY2014.23 Senate Appropriations Committee guidance for its subcommittees, however, indicated
a total for FY2014 consistent with BCA revised caps (i.e., a total of $1,058 billion split between a
base defense subtotal of $552 billion and a non-defense total of $506 billion).24
Differences between House and Senate discretionary spending levels were not resolved before the
start of FY2014 on October 1, 2013, which resulted in a shutdown of most federal operations.25
Funding for federal operations was restored by passage of a continuing resolution (H.R. 2775) on
October 16, 2013, which was signed by the President the following morning (Continuing

21 OMB, FY2014 Budget of the U.S. Government, p. 45. See Table 6 of memorandum cited below for $800 billion
estimate for difference between BCA revised caps and lowered caps.
22 According to the FY2014 Mid Session Review, “(t)he 2014 Budget includes allowances, similar to the Function 920
allowances used in Budget Resolutions, to represent amounts to be allocated among the respective agencies to reach the
proposed defense and non-defense caps for 2015 and beyond. These levels are determined for illustrative purposes but
do not reflect specific policy decisions.” See fn. 5, to Table S-10, p. 58; available at http://www.whitehouse.gov/sites/
default/files/omb/budget/fy2014/assets/14msr.pdf.
23 See CBO, “FY 2014 House Current Status of Discretionary Appropriations as of August 1, 2013,” available at
http://www.cbo.gov/sites/default/files/cbofiles/attachments/44333_BY2014House_8-1.pdf and OMB Sequestration
Preview Report (cited above). CBO estimated that the Homeland Security bill would include a $5.6 billion disaster
funding adjustment.

$986.3 billion before adjustments.26
The Bipartisan Budget Act of 2013 (H.J.Res. 59; P.L. 113-67) provided a reconciliation of House
and Senate discretionary spending levels for the remainder of FY2014 and for FY2015 as well.
The discretionary defense spending caps were set at $520.464 billion for FY2014 and $521.272
billion for FY2015. Non-defense caps were set at $491.773 billion for FY2014 and $492.356
billion for FY2015.27 The mechanism for reducing the revised BCA caps to lowered caps levels in
order to capture savings not attained by the Joint Select Committee on Deficit Reduction was
turned off for both FY2014 and FY2015.28 Both modified defense and non-defense spending
limits for FY2014 were $22.4 billion above the lowered caps levels that would have applied in
the absence of the Bipartisan Budget Act, while FY2015 levels were about $9 billion higher.29
Final Appropriations for FY2014
On January 13, 2013, the House and Senate Appropriations Committees announced agreement on
an appropriations measure that would provide funding for the remainder of FY2014 within the
limits set by the Bipartisan Budget Act. The agreement was incorporated into a Senate
amendment to H.R. 3547, retitled as the Consolidated Appropriations Act, 2014 (P.L. 113-76).
The House approved the measure on January 14, 2014, on a 359-67 vote and the Senate passed it
on a 72-26 vote the following day. The President then signed the act on January 17, 2014.
Discretionary Caps and Spending Trends
Discretionary spending as a share of GDP, if modified BCA caps remain in place, will decline to
levels well below that seen in recent decades. In real dollar terms (i.e., adjusting for inflation but
not for growth in population or the economy), discretionary base defense spending would revert
to a level slightly above its FY2007 level, while non-defense discretionary spending would revert
a level near its 2002 level.30 In later years, BCA caps would allow for modest growth in nominal
(i.e., not adjusted for inflation) terms. By contrast, mandatory spending and net interest costs are

26 That total excludes adjustments for war funding (OCO), disaster funding, program integrity, and emergency items.
Annualized funding reflecting those adjustments totaled $1,087.7 billion. See CBO, “CBO Estimate of the Continuing
Appropriations Act, 2014, as Introduced in the Senate on October 16, 2013, as an Amendment to H.R. 2775,” October
16, 2013; available at http://www.cbo.gov/sites/default/files/cbofiles/attachments/
ContinuingAppropriationsAct2014.pdf.
27 The defense category (i.e., the National Defense budget function (050)) is called the “revised security category” in
the BCA and the Bipartisan Budget Act of 2013. The non-defense category is called the “revised nonsecurity
category.”
28 BBEDCA Section 251A (2 U.S.C. 901a) directs OMB to lower the revised spending caps for FY2014-FY2021.
Section 101 of the Bipartisan Budget Act of 2013 requires that the lowering of caps “shall not be implemented for
fiscal years 2014 and 2015.”

FY2021,” by Amy Belasco and Andrew Austin, November 16, 2012, available from authors. This comparison is made
in terms of budget authority. Before passage of ATRA, BCA provisions were slated to bring discretionary base defense
spending to its FY2007 level and non-defense spending to near its level in FY2003 or FY2004. Inflation adjustments

projected to rise, implying that discretionary spending’s share of total federal spending would
continue to fall.
Actual discretionary budget authority totals will differ from BCA discretionary caps because
some types of spending are not subject to caps, such as war spending, certain amounts of disaster
relief assistance, and program integrity initiatives.31 In addition, scorekeeping adjustments
typically lead to differences between scored totals of budget authority used to check conformity
to BCA spending limits and other budget totals that do not include those adjustments.
Negative Budget Authority
Within the federal budget concepts, certain inflows, such as offsetting receipts, offsetting
collections, some user fees, and “profits” from federal loan programs, are treated as negative
budget authority.32 The federal government uses a modified form of accrual accounting for loan
and loan guarantee programs since passage of the Federal Credit Reform Act (FCRA) as well as
for certain federal retirement programs.33 OMB calculates net subsidy rates according to FCRA
rules for loan and loan guarantee programs. In some cases, FCRA calculations yield negative net
subsidy levels, implying that the federal government appears to make a profit on those loans.34
FCRA subsidy calculations, however, omit risk adjustments.35 The true economic cost of federal
credit guarantees can be substantially underestimated when risk adjustments are omitted.36
Historical Spending Trends
Federal spending trends in functional areas are affected by changing assessments of national
priorities, evolving international challenges, and economic conditions, as well as changing social
characteristics and demographics of the U.S. population. Some of the trends and events that have
had dramatic effects on federal spending are outlined below. Other CRS products provide
background on more specific policy areas.

31 Those caps are adjusted upwards to reflect those spending categories, within specified limits.
32 See OMB, FY2014 Budget, Analytic Perspectives, ch. 11, “Budget Concepts.” In particular, pp. 117-122 cover these
topics.
33 See out-of-print CRS Report RL30346, Federal Credit Reform: Implementation of the Changed Budgetary
Treatment of Direct Loans and Loan Guarantees
, by James M. Bickley, available upon request.
34 For example, some Federal Housing Administration mortgage programs and some federal student loan programs
have been estimated to yield negative net subsidies.
35 While the FCRA calculations include estimates of default costs, they do not discount more volatile income flows, as
a private firm would.

Discretionary Budget Authority by Subfunction: An Overview

Cold War, Peace Dividend, and the Global War on Terror
The allocation of discretionary spending between defense and non-defense programs is one
reflection of changing federal priorities over time. Figure 1 shows defense and non-defense
discretionary funding as a percentage of GDP. Figure 2 shows subfunctions within the National
Defense (050) budget function. The Department of Defense (DOD)-Military subfunction
accounts for over 95% of funding within that budget function.

Notes: Defense is defined as funding for the National Defense (050) budget function; non-defense is the
remainder. FY1976-FY2012 are historical data; FY2013 is estimated; FY2014-FY2018 reflect the President’s
FY2014 budget proposals. This figure assumes unspecified cuts to meet BCA caps are borne by non-defense
programs. See text for other important caveats.
Relations between the United States and its allies on one hand, and the Union of Soviet Socialist
Republics (USSR) and its allies on the other were the dominant security concern in the half
century following the Second World War. In the early 1970s, U.S. involvement in the Vietnam
War wound down, while the United States and the USSR moved towards detente, permitting a

Following intervention by the USSR in Afghanistan in 1979, military spending increased
sharply.38 Defense spending continued to increase until 1986, as concern shifted to domestic
priorities and the need to reduce large budget deficits. The collapse in 1989 of most of the
Warsaw Pact governments in Central and Eastern Europe and the 1990-1991 disintegration of the
Soviet Union was followed by a reduction in federal defense spending, allowing a “peace
dividend” that relaxed fiscal pressures.39

Discretionary Budget Authority by Subfunction: An Overview

The attacks on the World Trade Center towers in New York City and on the Pentagon on
September 11, 2001, were followed by sharp increases in homeland security spending. Defense
spending also increased dramatically with the start of the Afghanistan war in October 2001 and
the Iraq war in March 2003.40 U.S. combat troops were withdrawn from Iraq in December 2011,
and President Obama has announced that most U.S. troops would be withdrawn from Afghanistan
by the end of 2014.41
Spending on non-defense security spending also rose after the attacks of September 11, 2001, as
the federal government overhauled airport security procedures, and then established the
Department of Homeland Security. In 2005, hurricanes Katrina and Rita led to a spike in disaster
relief spending.42 Non-security spending also rose to fund new initiatives in education and in
other areas.43
In 2007, a severe credit crunch affected global financial markets, which led to a fully fledged
financial crisis in 2008 and a severe economic recession. The American Recovery and
Reinvestment Act of 2009 (P.L. 111-5; ARRA), designed to stimulate the economy and prevent
further slowing of economic activity, sharply increased federal spending on education, energy,
and support for state and local governments. ARRA also included broad tax cuts through a
Making Work Pay credit and other provisions. The decline in federal revenues and the increase in
spending caused the deficit to treble from $459 billion in FY2008 to $1.4 trillion in FY2009.
Since FY2010, base defense discretionary spending has been held flat and non-defense
discretionary spending has been reduced significantly.44 The BCA, as noted above, reimposed
discretionary spending limits that are slated to remain in place until FY2021.
The Recovery Act
After the financial crisis of 2007-2008 plunged the United States in the deepest economic
recession in decades, Congress passed the American Recovery and Reinvestment Act of 2009
(P.L. 111-5; ARRA), often known as the Recovery Act. ARRA includes support for state and
local governments in the form of increased infrastructure, Medicaid, school funding, funding for
health care IT, extended unemployment benefits, as well as tax cuts and rebates among other
provisions.45 According to initial CBO estimates, ARRA provisions were expected to total $787.2

(GWOT).

42 See CRS Report R40708, Disaster Relief Funding and Supplemental Appropriations for Disaster Relief, by Bruce R.
Lindsay and Justin Murray.
43 The Obama Administration defined security spending in its FY2012 budget as funding for Department of Defense-
Military (subfunction 051); the Department of Energy’s National Nuclear Security Administration; International
Affairs (function 150, which includes State Department and related agencies); the Department of Homeland Security;
and the Department of Veterans Affairs. The BCA defined security similarly, except that it included all military
activities within the Department of Defense excluding war funding (i.e., defined by department rather than by
subfunction), and also included the Intelligence Community Management Account.
44 The base defense budget excludes war funding (Overseas Contingency Operations).

Discretionary Budget Authority by Subfunction: An Overview

Federal Health Programs
Costs of federal health programs continue to play a central role in budgetary discussions. The
costs of the largest federal health programs, Medicare and the federal portion of Medicaid costs,
are nearly all mandatory. Administrative costs, which account for a small portion of those costs,
are nearly all funded as discretionary spending. Federal health research and veterans’ health care
is mostly funded through discretionary spending, as are certain public health clinics. Trends in
funding of health subfunctions are shown in two separate figures. Larger programs (health care
services/subfunction 551 and Medicare/function 570/subfunction 571) are shown in Figure 4, and
smaller programs (health research and training/subfunction 552 and consumer and occupational
health and safety/subfunction 554) are shown in Figure 5. The National Institutes of Health
(NIH) are the largest part of the health research and training subfunction. Veterans’ health
programs, which fall under the veterans benefits and services function, are also shown in Figure
8
to make comparisons among those programs easier.
