Trends in Discretionary Spending

Summary
Discretionary spending is provided and controlled through appropriations acts, which 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.
Federal spending in 2010 is estimated at just under a quarter (24.5%) of the U.S. economy, as
measured by gross domestic product (GDP). Federal spending since 1962 has averaged about a
fifth of GDP. (Years denote federal fiscal years unless noted otherwise.) Discretionary spending
accounted for 37.8% of total outlays in 2010, as extraordinary federal responses to financial
turmoil sharply increased mandatory spending (56.15% of outlays in 2010), reducing
discretionary spending’s share of total spending. Net interest accounted for 6.1% of federal
outlays in 2010.
In 1962, discretionary spending accounted for 47.2% of total outlays and was the largest
component of federal spending until the mid-1970s. Since then, discretionary spending as a share
of federal outlays and as a percentage of GDP has fallen. The long-term fall in discretionary
spending as a share of total federal spending is largely due to rapid growth of entitlement outlays
and slower growth in defense spending relative to other federal spending in past decades.
Discretionary spending is often divided into defense, domestic discretionary, and international
outlays. Trends in those categories may indicate broad national priorities as reflected in federal
spending decisions. Defense and domestic discretionary spending compose nearly all of
discretionary spending. In 1962, discretionary spending equaled 12.3% of GDP, with defense
spending making up 9.0% of GDP. In 2010, total discretionary spending is estimated to fall to
9.3% of GDP with defense spending totaling 4.7% of GDP. Military spending has increased
sharply over the last decade. On average, from 2000 to 2010, defense outlays grew 6.8% per year
in real terms, whereas non-defense discretionary outlays grew 5.6% per year in real terms.
The G. W. Bush and Obama Administrations each created their own division of security and non-
security spending. Dividing spending into security and non-security components, however,
presents many conceptual and practical difficulties. Some federal activities, such as Coast Guard
patrols, advance non-security and security interests. Furthermore, federal programs tasked with
non-security aims in normal times may respond to specific homeland security challenges. Non-
defense security discretionary budget authority increased sharply after Hurricane Katrina,
although changes in outlays were less dramatic. Non-defense non-security outlays, which have
ranged between 3% and 3.5% of GDP since the mid-1980s, are estimated to reach about 4% of
GDP in 2010, largely due to economic stimulus measures and other recession-related spending.
The Obama Administration in its recent budget submission called for a three-year freeze on non-
security discretionary spending. Weak economic conditions have depressed federal revenues and
may continue to increase government social safety-net expenditures. Some contend that
additional stimulus measures are needed to reduce high unemployment levels, while others have
called for imposing greater budgetary stringency. Over the long term, projected future growth in
entitlement program outlays may put severe pressure on discretionary spending unless policy
changes are enacted or federal revenues are increased.
This report will be updated as events warrant.

Trends in Discretionary Spending

What Does Discretionary Spending Include?
Discretionary spending is provided in, and controlled by, annual appropriations acts, which fund
many of the routine activities commonly associated with such federal government functions as
running executive branch agencies, congressional offices and agencies, and international
operations of the government.1 Essentially all spending on federal wages and salaries is
discretionary.2
Discretionary spending is often contrasted with mandatory, or direct, spending. Mandatory
spending includes federal spending on entitlement programs, the Supplemental Nutrition
Assistance Program (formerly known as the Food Stamps program), and other spending
controlled by laws other than appropriation acts.3 Spending levels for mandatory programs are
generally controlled by eligibility criteria and size of the eligible population.
Budget Authority and Outlays
The distinction between outlays and budget authority is important to understanding the federal
budget and, particularly, discretionary spending. Appropriations legislation, which controls
discretionary spending, grants budget authority to accomplish specific ends. Budget authority is
what federal agencies can legally spend. Budget authority has been compared to funds deposited
into a checking account, which then can be used for specified federal purposes. Outlays are
disbursed federal funds. Therefore, an outlay is not recorded until the federal government
disburses appropriated funds to purchase goods and services.
Table 1 illustrates the different categories of federal spending (i.e., mandatory and discretionary
spending) by contrasting the type of budget authority needed for specific purposes.
Outlay data are used to assess the macroeconomic effects of the federal budgets, whereas budget
analysis of specific federal programs is typically based on budget authority, because that is what
Congress controls directly. Congressional appropriations, which grant budget authority for
specific purposes, are not always tightly linked to changes in outlays in the following year. While
budget authority can be granted for a single year, some appropriations (such as for many military
construction projects) provide budget authority for multiple years, or indefinitely. Thus outlays
that flow from an appropriated sum might be spread over several fiscal years, implying that
budget authority totals will differ from outlay totals for a single fiscal year.4

1 Annual appropriations acts fall within the jurisdiction of the House and Senate Appropriations Committees.
2 Exceptions exist. For example, salaries for Members of Congress, the President, and federal judges are classified as
mandatory spending, as are essentially all federal retirement and disability costs. Direct spending is controlled by
committees with legislative jurisdiction.
3 For details, see CRS Report RL33074, Mandatory Spending Since 1962, by D. Andrew Austin and Mindy R. Levit.
4 While federal officials often have some discretion to choose how quickly appropriated funds are spent, they face
constraints imposed by legislation designed to protect Congress’s power of the purse. According to the Anti-Deficiency
Act, a federal official cannot spend government money beyond what is available through appropriations or a fund by
law. See Government Accountability Office, Antideficiency Act Background, available at http://www.gao.gov/ada/
antideficiency.htm for code citations and explanations. The Congressional Budget Act and Impoundment Control Act
of 1974 (P.L. 93-344) limits the ability of federal officials to withhold or delay spending of appropriated funds without
Congressional approval.

Trends in Discretionary Spending
The composition of the federal budget has changed dramatically since the early 1960s. Over time,
the share of total discretionary spending in federal spending has fallen, whereas the share of
mandatory spending has increased. Discretionary spending accounted for 67.5% of total outlays
in 1962, but only 37.8% of total outlays in 2010.5 Mandatory spending, by contrast, rose from
26.1% of total outlays in 1962 to 56.1% in 2010. Net interest accounted for 6.1% of federal
outlays in 2010.
In contrast to the longer term trends, between 2000 and 2010, discretionary spending grew more
quickly than mandatory spending. After falling for three decades between the late 1960s and the
late 1990s as a share of the economy, discretionary spending increased 6.2% a year in real terms
on average from 2000 to 2010. Over the same period, the share of discretionary spending as a
proportion of federal outlays grew from 34.4% in 2000 to 37.8% in 2010.
The economic recession that began in late 2007 reduced incomes and increased unemployment,
which in turn increased the number of people eligible for income support programs and outlays
on some discretionary programs. Extraordinary federal responses to financial turmoil in 2008 and
2009, however, increased mandatory spending even more sharply, which reduced the share of
discretionary spending in federal outlays. More normal financial conditions and renewed
economic growth in the second half of calendar year 2009 helped moderate spending on some
mandatory programs and stem decreases in Medicare and Social Security payroll tax revenues.
While the economy began growing again in calendar year 2009, growth in 2010 has been weaker
than expected. Estimates put real annualized growth in the first quarter of 2010 at 3.7% and only
1.6% for the second quarter.6 Several sectors show signs of recovery, but the national

unemployment rate, which was 9.6% in August 2010, is projected to fall slowly.7 CBO estimates
that the unemployment rate will not recede to the 5% level until 2014.8 Some economists have
become more worried about the possibility of a “double-dip” recession, which would complicate
existing budgetary challenges, although many forecasters do not predict a “double-dip.”
How Has the Composition of Discretionary Spending Changed?
In 1962, discretionary spending comprised 67.5% of total outlays, with mandatory spending and
net interest accounting for 26.1% and 6.5%, respectively. Discretionary spending as a share of
total outlays peaked in 1963. By 2009, discretionary spending fell to 35.2% of total outlays,
though it increased to 37.8% in 2010. Mandatory spending accounted for 56.1% of total outlays,
with net interest at 6.1% in 2010.9 Figure 1 shows discretionary and mandatory spending, and net
interest payments—categories defined in the Budget Enforcement Act (P.L. 101-508)—since
1962 as a share of total outlays.
The peak estimated in mandatory spending in 2009 is largely attributable to the state of the
economy and enacted federal financial interventions, leading to an analogous spike in overall
spending. This also led to a decline in discretionary spending’s share of total outlays (from 38.0%
in 2008 to 35.2% in 2009), though discretionary spending is estimated to rise in nominal terms.
Over the longer term, discretionary spending’s share of total outlays is projected to decline
further. By 2020, according to CBO baseline projections that assume projected discretionary
outlays hold steady in real terms, discretionary spending will fall to a historical low of 29.3% of
total outlays.10

Trends in discretionary spending as a share of gross domestic product (GDP) provides another
perspective on how the composition of federal outlays has changed. Measuring budget
components as a share of GDP compares their size to the economy as a whole, and implicitly
incorporates inflation and population growth. Figure 2 shows components of federal spending as
a percentage of GDP since 1962.

While discretionary spending was the largest component of federal spending until the mid-1970s,
mandatory spending in 2009 accounted for nearly three-fifths of total federal spending. In 2009,
mandatory spending accounted for about 6% more of GDP than discretionary spending, although
that gap is expected to narrow to 3.9% in 2010.
Medicare and Medicaid have continued to grow faster than overall federal spending, contributing
to the majority of the increase in mandatory spending over this period. Social Security spending,
the other large component of mandatory spending, has been relatively stable in the last decade
when measured as a share of GDP.
Total federal spending as a share of GDP is estimated to have peaked in 2009 as a result of the
current economic situation and enacted federal financial interventions. While discretionary
spending declined as a percentage of total outlays in 2009, it rose as a percentage of GDP because
the economy shrank in 2008 and early 2009. Over the longer term, discretionary spending’s share
of GDP is projected to decline further. By 2020, discretionary spending is projected to fall to
6.7% of GDP, similar to the levels it reached in the late 1990s and early 2000s.
Because of the decline in discretionary spending as a percentage of total outlays and as a
percentage of GDP and the resulting increase in the share of mandatory spending over time,
controlling the federal budget may have become more difficult for Congress. In other words,
because net interest payments and mandatory spending are set automatically, less money is

available to allocate to other government agencies and programs unless revenues rise or Congress
modifies eligibility requirements and benefits of mandatory spending programs.
Discretionary Spending and National Priorities
Discretionary spending can be subdivided into defense, domestic, and international categories.
Such divisions may provide a rough indicator of national priorities as reflected in federal
spending decisions. Figure 3 shows these categories of discretionary spending as a share of GDP
over the period 1969-2009. Discretionary defense spending as a percentage of GDP fell from
8.7% in 1969 to 3.0% in 2000, and then rose to an estimated 4.7% of GDP in 2010. Over the
same period, domestic and international discretionary spending have changed less dramatically as
a percentage of GDP. Domestic discretionary spending increased in the late 1970s but fell in
subsequent decades as a share of the economy, remaining closer to its post-1969 average.
Although discretionary spending has increased rapidly in the past half decade, spending in some
government departments and agencies has grown very slowly or has been cut, while spending in
other areas has expanded rapidly. Funding for defense and emergency and disaster management
increased after the events of September 11, 2001, and even more sharply in the wake of Hurricane
Katrina. In recent years, disaster funding has receded, allowing non-defense discretionary
spending as a share of GDP to fall until federal responses to the economic recession pushed
spending back up.
Discretionary Defense Spending
Defense spending increased sharply in the mid-1960s as the United States’ involvement in
Vietnam deepened. After large-scale withdrawals of American troops from Vietnam began in
1969, defense spending as a share of GDP fell for the next decade. The Soviet invasion of
Afghanistan prompted the Carter Administration, and then the Reagan Administration, to boost
military expenditures resulting in an increase in defense spending during the early 1980s. After
the Berlin Wall was opened in November 1989 and communist governments in central and
eastern Europe collapsed, defense spending as a share of GDP dropped to historically low levels,
providing what some called a “peace dividend.” Defense spending again rose after the attacks of
September 11, 2001, and wars in Afghanistan and Iraq began.

request for a $33 billion supplemental for the Afghan surge. FY2010 reflects DOD’s request for its base budget
and an additional $159 billion for war costs.
Increased defense spending accounted for 53% of the increase in discretionary spending in real
terms over the past decade. Discretionary defense spending increased 6.8% per year on average in
real terms between 2000 and 2010.11 Discretionary defense spending, which had fallen to 3.0% of
GDP by the late 1990s, rose sharply to 4.0% of GDP in 2005, and is estimated to reach 4.7% of
GDP in 2010. The trajectory of defense discretionary spending depends in large part on the scale
of future operations in Iraq and Afghanistan, as well as on decisions about major procurement
programs.
The appropriate size of the defense budget has long been a lively topic of debate. In 2007,
General Mike Mullen, Chairman of the Joint Chiefs of Staff, had said that he considered 4% of
GDP “an absolute floor” for future defense spending.12 Some analysts have expressed some

doubts about the sustainability of current defense budget plans.13 Others contend that defense
expenditures as a proportion of GDP should be expected to fall over the long term because the
cost of defending the nation depends on factors that are largely independent of economic growth.
Secretary of Defense Robert Gates has called for cost-cutting measures within the Department of
Defense, although the stated aim is not to reduce the Department’s top-line budget number.14
Discretionary Domestic Spending
Trends in domestic discretionary spending are less dramatic. Domestic spending supports the
largest number of federal agencies and programs, including science and technology research,
natural resources, energy, education, and numerous others. None of the individual programs
within the domestic discretionary category have approached 1% of GDP since 1962. Most of
these programs spent less than 0.5% of GDP during that period.
Domestic discretionary spending, 3.2% of GDP in 1969, rose to a peak of 4.8% in 1978.
Domestic non-defense discretionary spending’s share of GDP fell during the Reagan
Administration, reaching 3.1% of GDP in 1987.15 Since then it has fluctuated between 3.0% and
3.6% of GDP. Domestic discretionary spending in 2009 accounted for 4.1% of GDP.
Discretionary International Spending
Discretionary spending for international programs since 1969 has averaged 0.3% of GDP,
reaching its peak of 0.5% of GDP in 1975. Since that time, international spending has generally
trended downward. Between 2001 and 2010, spending on international programs rose from 0.2%
of GDP to 0.3% of GDP. The majority of the funding in this category in recent times has been
devoted to diplomatic missions, foreign aid, and international finance.
Discretionary Security and Non-Security Spending
The G. W. Bush and Obama Administrations have each created their own division of security and
non-security discretionary spending as a way of communicating their budgetary priorities. The
Obama and Bush Administration budgets have presented summaries of discretionary funding that
split out security spending from non-security spending.16 Unlike the division of discretionary

spending into the categories of domestic, international, and defense, which has become routine in
budget analyses, no standard method of dividing security spending from non-security spending
has been universally accepted. In particular, the G. W. Bush and Obama Administration
definitions vary in significant ways.
What is “Homeland Security” or “Security” Spending?
Any division of spending into security and non-security components would likely present
conceptual and practical difficulties.17 Moreover, the widely used term “homeland security,”
which comprises some but not all non-defense security spending, does not already readily
translate in budgetary categories. Figure 4 provides a schematic view of Department of Defense
and security spending as defined by the Obama Administration.
The Obama Administration defines security spending as funding for:
• Department of Defense-Military;
• Department of Energy’s National Nuclear Security Administration;
• International Affairs (function 150; includes State Department and some other
agencies);
• Department of Homeland Security; and
• Department of Veterans Affairs.18
Activities within budget subfunction 053 (Atomic Energy Defense Activities) outside of the
National Nuclear Security Administration by this definition are classed as non-security. While the
G. W. Bush Administration defined certain parts of the Department of Homeland Security within
its “security” classification, the Obama Administration includes all of that department’s funding.

Trends in Discretionary Spending

The G. W. Bush Administration defined security funding as spending on the “Department of
Defense, Homeland Security activities Government-wide; and International Affairs.”19 The
Obama Administration includes funding for the Department of Veterans Affairs and excludes
Justice Department agencies such as the Federal Bureau of Investigation (FBI) under its security
rubric, while the Bush Administration’s definition included the FBI and other law enforcement
bureaus and excluded the Department of Veterans Affairs.
Most homeland security spending, by either definition, takes place in the Department of Defense,
the Department of Homeland Security, and the Department of Energy. Many other federal
agencies spend at least some portion of their budget on what are arguably homeland security
tasks, so that a significant amount of homeland security spending takes place in agencies and
programs whose primary focus is not security oriented. Some federal activities, such as Coast
Guard patrols and research at the Centers for Disease Control and Prevention, advance interests
clearly linked to security objectives as well as those which are not. Moreover, some federal
programs tasked with non-security aims in normal times may respond to specific homeland
security challenges. These issues complicate budgetary analyses of homeland security spending.
The President’s budget submission must report homeland security spending.20 This definition,
drawn more narrowly than “security,” can exclude some activities not closely tied to security
concerns, such as military bands. OMB’s security spending estimates are based on reports from
32 agencies with homeland security responsibilities. Those agencies provide OMB with budget
reports that provide a level of detail unavailable in publicly available data.
Trends in “Security” and “Non-Security” Discretionary Spending
Figure 5 shows trends in discretionary spending, divided into defense, non-defense security, and
non-security categories in terms of budget authority, while Figure 6 shows the same categories in
terms of outlays. Because budget authority can translate into outlays that stretch over several
years, changes in outlays tend to be more gradual.
Non-security discretionary spending (according to an approximation of the Bush Administration
security spending definition), which had been about 6% of GDP in the late 1970s, dropped
sharply in the early 1980s before stabilizing around 3% of GDP after 1986.21 Changes in non-
defense security discretionary spending have been less dramatic. Table 2 shows average real
growth rates for security and non-security components of discretionary spending.

Trends in Discretionary Spending

The Obama Administration in its first budget submission contended that many domestic priorities
had been underfunded and proposed several cuts in defense spending, many of which Congress
adopted.22 The Obama Administration in its FY2011 submission, however, called for a three-year
freeze on discretionary non-security spending.23 Previously, the Bush Administration had said that
holding down growth in “non-security” discretionary spending was a major fiscal priority.24 Non-
security discretionary outlays (using the Bush Administration definition) rose from 3.1% of GDP
in 2007 to 4.2% of GDP in 2010, after having increased earlier in the decade. Non-defense
security discretionary budget authority increased sharply after Hurricane Katrina hit in 2005,
while changes in outlays, shown in Figure 6, were less dramatic, in large part because the Gulf
Coast recovery lasted longer than expected.25
Fiscal Stimulus and the Budget
Congress in early 2009 responded to weak economic conditions and dramatic job losses that
sharply increased unemployment rates by passing a major fiscal stimulus package.26 The resulting
measure, the American Recovery and Reinvestment Act of 2009 (ARRA; H.R. 1, P.L. 111-5),
enacted on February 17, 2009, included stimulus spending and tax cuts estimated at the time to
total $787.2 billion. ARRA includes funds for discretionary spending on education initiatives,
support for state governments, public housing, infrastructure, and health care. CBO more recently
estimated the total budgetary effect of ARRA at $814 billion between 2009 and 2019.27 Certain
Supplemental Nutrition Assistance Program (SNAP) benefits were cut by P.L. 111-226 (H.R.
1546), which is projected to reduce ARRA spending in future years.28
Debate continues on whether additional economic stimulus would be appropriate. Some
economists argue that weak economic growth and persistently high unemployment rates require
additional fiscal stimulus.29 Other economists are skeptical that Keynesian demand management
would ameliorate deeper problems caused by high personal and federal debt levels.30 On

22 For example, the Administration states that “now is precisely the time for the country to make the long overdue
investments that will fundamentally transform our economy so that we can compete and thrive in the decades ahead.”

Trends in Discretionary Spending

September 7, 2010, President Obama proposed a $50 billion package of infrastructure
investments along with proposals to extend permanently certain R&D tax credits and other
measures to stimulate business investment.31
The FY2011 Budget and Beyond
Budgetary priorities may change as the Obama Administration and Congress confront ongoing
financial and economic challenges. In response to economic downturn, federal spending has
automatically increased as more people have become eligible for income support programs and
revenues have decreased as incomes of households and profits of many firms have fallen. These
“automatic stabilizers” have a countercyclical effect, although most macroeconomists doubt that
they would be themselves sufficient to stave off slow growth for the next few years.
In addition to “automatic stabilizers,” the federal government has responded to this financial
turmoil with an extraordinary set of measures aimed at housing and credit markets. In February
2008, Congress enacted a $152 billion package (P.L. 110-185, Economic Stimulus Act of 2008) to
stimulate consumption that sent refunds to taxpayers and let firms depreciate their capital more
quickly. Later in the year, the Federal Reserve created a panoply of lending facilities to provide
financial institutions with loans in exchange for various types of collateral. On October 3,
Congress passed the Emergency Economic Stabilization Act of 2008 (EESA; P.L. 110-343),
which authorized the Treasury Secretary to use $700 billion (subject to certain Congressional
restrictions and notifications) to intervene in financial markets or to inject capital into key
financial institutions as part of a Troubled Asset Relief Program (TARP).
The ultimate costs of these responses and their budgetary impact will depend on how the
economy performs, how well firms with federal credit guarantees weather future financial shocks,
and whether the government receives positive returns on its asset purchases. Several major
financial institutions have repaid TARP funds to Treasury.
New shocks to the financial system and the economy could present Congress with new demands
for federal responses. Many state governments continue to face significant budget challenges,
residential and commercial real estate markets remain depressed in many parts of the country, and
many households are struggling with high debt levels and an uncertain labor market. Mandatory
spending tied to means-tested social programs has been increasing due to persistent
unemployment, while federal revenues will likely fall as individuals’ incomes drop and corporate
profits sink. Funding requests for military operations in Iraq and Afghanistan will likely continue.
New policies and requests, if implemented, could affect discretionary spending levels in FY2011
and beyond.
Discretionary Spending in the Long Term
Congress can change, continue, or reverse trends in discretionary spending directly through
annual appropriations decisions, or indirectly by modifying certain federal budget procedures,

Trends in Discretionary Spending

such as reinstating statutory limits on discretionary spending. If discretionary spending were held
constant in real terms, as the CBO baseline presumes, then discretionary spending per capita
would decrease as population grows and it would shrink as a share of GDP as the economy
grows. On average the U.S. population grew 1% a year and per capita GDP grew 2.25% per year
from 1962 to 2005.32 If those trends were to persist, then holding discretionary spending constant
in real terms implies per capita discretionary spending would shrink by 1% a year and
discretionary spending as a share of the economy would shrink by 3.25% per year.
Over the long run, growth in entitlement spending will present severe fiscal challenges. Recent
research on long-term fiscal challenges has focused on continued increases in the per beneficiary
cost of health care, as well as the more predictable demographic changes that will occur as the
baby boom generation retires. Projections from a variety of sources predict that spending on
Medicare and Social Security will increase sharply as a share of GDP in coming decades.33 CBO
projects that Medicare will expand from 4.0% of GDP in 2020 to 9.0% in 2050 and to 13.5% in
2080. Social Security outlays are projected to grow from 5.3% of GDP in 2020 to 6.0% of GDP
by 2035. Federal Medicaid outlays, 1.8% of GDP in 2008, are projected to reach 3.2% of GDP in
2050.34
Social Security, Medicare, and Medicaid outlays as a proportion of GDP are projected to equal or
exceed the present share of federal revenues as a proportion of GDP (17.7% in 2008) sometime
before the middle of the 21st century. Maintaining current levels of discretionary spending would
then require either substantial tax increases or major changes in those entitlement programs.

Appendix. Approximating the Definition of
“Security” Spending Used in the G. W. Bush
Administration

Table A-1 lists parts of the federal government whose funding is used to approximate the G..W.
Bush Administration’s definition of security spending. This approximation of security spending
categories is defined using federal subfunction- and account-level data from the OMB Public
Budget Database. Table A-1 specifies which items are included in this definition of security
spending. This definition of security spending has the advantage that it can be applied over a
longer period of time, providing historical context for current spending decisions.35
This listing uses OMB function and subfunction codes along with specific account codes to
identify agencies and programs that match, at least in large part, the definition of security
spending put forth in the President’s FY2009 budget submission.36 As noted in the text, some
activities such as U.S. Coast Guard harbor patrols may serve security and non-security ends.
Some agencies, such as the Centers for Disease Control and Prevention, perform some tasks that
are closely associated with security concerns as well as other tasks that are not. Finally, some
grant programs designed to support non-security aims have been used to address security
concerns such as recovery from the events of September 11, 2001.
Figure A-1 shows trends in discretionary spending in terms of budget authority, divided by
security and non-security categories using the approach described above. Figure A-2 presents
those trends in terms of outlays.

35 OMB historical data from different years are not necessarily fully comparable due to changes in accounting
treatment, redefinition of activity areas, changes in the structure of federal agencies, and for other technical reasons.
