Among other findings, this report shows the following:
Research Assistant
In April 2020, the unemployment rate reached 14.8%—the highest rate observed
since data collection began in 1948. In March 2021, unemployment remained
higher (6.0%) than it had been in February 2020 (3.5%).
The labor force participation rate declined to 60.2% in April 2020—a level not seen since the
early 1970s—before partial y recovering in March 2021 (61.5%).
Nonfarm payrolls shed 22.1 mil ion jobs between January 2020 and April 2020, with employment
declining to 86% of its pre-recession level. In March 2021, aggregate employment remained 8.1
mil ion jobs below its pre-recession level.
The COVID-19 pandemic has impacted economic sectors disparately. The leisure and hospitality
sector lost the largest number of jobs since January 2020, and persons last employed in this sector
have consistently exhibited some of the highest unemployment rates throughout the pandemic.
Additional y, the education and services sector and the government sector have exhibited the
second and third-largest losses in jobs since January 2020, despite relatively low unemployment
rates among persons last employed in these sectors.
The COVID-19 pandemic has impacted demographic groups disparately. Although al
demographic groups were affected, persons identifying as Black or Hispanic and younger
workers general y experienced relatively high peaks in unemployment and relatively steep
declines in labor force participation over the course of the pandemic. Additional y, persons with
lower educational attainment have general y experienced relatively higher unemployment rates
and lower labor force participation throughout the pandemic.

Unemployment Rates During the COVID-19 Pandemic
Introduction
The National Bureau of Economic Research declared the start of the current economic downturn
in February 2020, marking the end of the longest period of expansion in U.S. history.1 This
expansion followed the Great Recession (December 2007 to June 2009), a downturn widely
considered to be the worst since the Great Depression (August 1929 to March 1933).2 The
unemployment rate rose quickly in March 2020, and by April 2020 it had greatly surpassed its
previous peaks observed during and just after the Great Recession. This rise in unemployment
was caused by an unprecedented loss of 22.1 mil ion jobs between January 2020 and April 2020.
Many individuals left the labor force over this period, and by April 2020 the labor force
participation rate3 declined to a level not seen since the early 1970s.
This deterioration in the U.S. labor market corresponded with various advisory or mandated stay-
at-home orders implemented in response to the Coronavirus Disease 2019 (COVID-19) pandemic
and other pandemic-related factors affecting U.S. demand.4 States and localities implemented
these orders5 to mitigate the risks of COVID-19 after it was declared a pandemic disease by the
World Health Organization on March 11, 2020.6
This report discusses the state of the U.S. labor market using data from the Bureau of Labor
Statistics (BLS). The three primary sources are the Current Population Survey (CPS), the Local
Area Unemployment Statistics (LAUS) program, and the Current Employment Statistics (CES)
program. In addition to the usual caveats about estimates (see the “General Data Caveats”
section), there were additional data chal enges caused by the COVID-19 pandemic (see the
“COVID-19 Pandemic-Related Data Issues” section). The pandemic led to lower survey response
rates by businesses and households, and BLS detected an error in their categorization procedures
that likely underestimated unemployment early in the recession.7 Labor force participation rates
were not affected by this categorization error and met BLS standards of accuracy, despite
depressed response rates.8 Recently, BLS identified an error in the nonfarm enrollment data

and unprecedented decreases in labor force participation. T he unemployment rates observed during the Great

Recession see CRS Report R45330, Labor Market Patterns Since 2007, by Sarah A. Donovan and Marc Labonte.

processing system wherein some businesses were improperly included in estimates, although the
impacts of this error are yet to be evaluated.9
This report general y finds the following:
The unemployment rate peaked10 in April 2020, at a level not seen since data
collection started in 1948, before declining to a level in March 2021 that stil
remained 2.5 percentage points above the rate observed in February 2020.
In April 2020, the labor force participation rate declined to levels not seen since
the early 1970s.
Nonfarm payrolls shed 22.1 mil ion jobs between January 2020 and April 2020.
In March 2021, aggregate employment remained 8.1 mil ion jobs below its pre-
recession level.
U.S. Unemployment Rate: Historical Trends
Prior recessions typical y developed with gradual y increasing economic distress. The current
recession was caused by the COVID-19 pandemic, which was an abrupt and exogenous shock to
the economy. The pandemic resulted in rapidly implemented efforts to limit contact among
individuals and many shutdown orders. Therefore, the trends in the unemployment rate in the
current recession differ from those in prior recessions (see Figure 1). Rates observed during prior
recessions rose relatively gradual y over the course of an economic downturn and then peaked.
The current recession exhibited an unprecedented sharp increase in the unemployment rate (10.3
percentage points) from February to April 2020.11 Following April, the rate declined rapidly (6.4
percentage points from April 2020 to August 2020) as temporarily furloughed workers returned to
work. Despite these rapid declines, the unemployment rate remains at an elevated level (6.0%)
compared to February 2020. The share of workers on furlough has declined since peaking in April
2020, while the share of permanently laid off workers has steadily increased.12 Although
economic projections have general y improved since early in the recession, the Congressional
Budget Office (CBO) has projected that unemployment rates over 5.0% wil persist over the next
two years.13

Notes: Shaded regions indicate recessionary periods as identified by the National Bureau of Economic Research.
The unemployment rate’s relatively rapid decline since April 2020 may have been aided by laws
passed in response to both the recession and the pandemic. Notably, Congress has passed three
rounds of stimulus checks for families,14 expanded nutrition assistance programs,15 and enacted
increases in refundable tax credits.16 These provisions increased families’ disposable income and
may have increased consumer spending, enabling businesses to better endure the recession; a
2020 study from NBER found that higher replacement rates of lost wages led to higher consumer
spending.17 Congress also enacted the Paycheck Protection Program, which provides loans that
can be fully forgiven if the majority of funds are used to maintain payrolls.18
Additional y, Congress expanded Unemployment Insurance (UI) program benefits and extended
length of coverage.19 This policy could directly increase the unemployment rate because past
research has shown UI extensions can increase the duration of unemployment for a relatively

smal segment of unemployed workers.20 A recent paper examining data from April to July of
2020 found that while UI benefit increases reduced employment by 0.2% to 0.4%, overal
spending by recipients increased by 2.0% to 2.6%.21 The authors note that while these expansions
directly decreased employment among recipients, that increased spending among recipients may
have insulated the labor market from further deterioration.
These (and other) policies may have affected unemployment rate trends in several ways; however,
the causal impact of policy choices on the unemployment rate is beyond the scope of this report.
Comparing the Great Recession and the COVID-19 Recession
During the Great Recession, the unemployment rate increased from 5.0% in December 2007 (the
start of the recession) to 9.5% in June 2009 (the end of the recession) (see Figure 2). The
unemployment rate peaked at 10.0% in October 2009, four months after the recession official y
concluded. In the current recession, the unemployment rate increased from 3.5% in February
2020, to 4.4% in March 2020, and then peaked at a high of 14.8% in April 2020. Since then, the
unemployment rate fel to 6.0% in March 2021. The peak represents the quickest month-over-
month increase in the unemployment rate and the highest overal unemployment rate since the
CPS data started being collected in 1948.22

COVID-19 Recession: Unemployment Trends
The COVID-19 pandemic has affected the unemployment rates for every state, economic sector,
and major demographic group. In the early stages of the current recession, unemployment rates
disproportionately increased among economic sectors delivering in-person services. Some
demographic groups are overrepresented in such sectors, contributing to higher unemployment
rates for those workers.23
Unemployment Rates by State
Figure 3 displays state-level monthly unemployment rates from January 2020 to February 2021
(the data for March and April 2021 have not been released as of the cover date of this report). The
figure shows that no state was immune from economic damage early in the pandemic.24 Since the
onset of the current recession, the unemployment rate for every state and the District of Columbia
surpassed levels seen during the Great Recession. The variation in economic damage was due to a
number of factors, including the proportion of jobs in sectors that provide non-essential services
to in-person customers,25 individual concerns of contracting COVID-19 causing declines in
personal consumption,26 and the implementation of stay-at-home orders and business closure
policies.27

Notes: The National Bureau of Economic Research identified February of 2020 as the first month of the current
recession. The month-over-month changes are point estimates and have not been tested for significance. The
data for March and April 2021 have not been released as of the cover date of this report.
The unemployment rate in most states peaked in April 2020 and has since declined. In February
2021, the states with the highest unemployment rates were Hawai (9.2%), New York (8.9%),
California (8.5%), Connecticut (8.5%), and Nevada and New Mexico (both at 8.3%). The states
with the lowest unemployment rates in February 2021 were South Dakota (2.9%), Utah (3.0%),
Nebraska (3.1%), Vermont (3.1%), and Kansas (3.2%).
Unemployment Rates by Sector
Figure 4 displays the change in sector unemployment rates from January 2020, before the start of
the recession, to March 2021. Sector unemployment rates define the unemployment rate among
individuals whose last job was in a particular sector. The figure shows that some sectors were
disparately impacted by the recession, although the data are not seasonal y adjusted. Without
seasonal adjustments, it is difficult to determine the extent to which unemployment trends are
related to the recession or to seasonal trends. Readers should interpret trends shown in Figure 4
with some caution as this report does not test for statistical significance of these differences.
Workers whose last job was in the leisure and hospitality sector experienced a higher peak in
unemployment (39.3% in April 2020) than did workers who were previously employed in any
other sector; they also had the second highest unemployment rate in March 2021 (13.0%).
However, elevated unemployment rates are not constrained to sectors providing in-person

services. Workers whose last job was in the mining or extraction sector have experienced steadily
increasing unemployment since the onset of the recession; in March 2021 they exhibited the
highest rate (15.0%) among al workers across sectors. The lowest March 2021 rates were among
workers whose last job was in the government (2.7%), financial activities (3.4%), or education
and health services (3.8%) sectors. These sectors have had unemployment rates below 15% from
February 2020 through March 2021.28 Within sectors, some workers were more likely to lose
their jobs than others early in the recession. For example, some studies from early in the
pandemic suggest that low-wage workers in the leisure and hospitality sector and other services
sectors experienced disproportionately large employment losses.29

Unemployment Rates During the COVID-19 Pandemic
Unemployment Rates for Full- and Part-Time Workers
As shown in Figure 5, part-time workers experienced a higher peak unemployment rate (24.5%
in April 2020) than full-time workers (12.8% in April 2020). This disparity has closed as the
recession has progressed, as the unemployment rate for part-time workers in March 2021 (5.8%)
is less than the unemployment rate for full-time workers (6.1%).
There are a few reasons why part-time workers’ apparent economic recovery since April may not
reflect the realities they face. First, some workers who last worked part-time jobs may have left
the labor force, and hence are not counted in the official unemployment statistics used in this
report. It is unclear whether that is the case. Additional y, there was a considerable increase in the
number of part-time workers who reported that they would have preferred to work full-time but
work part-time because their hours were reduced or they could only find part-time jobs.30 This
could be reflected as a reduced unemployment rate among part-time workers. Further, BLS has
observed that labor underutilization has remained elevated for workers, including those who have
been working part-time for economic reasons.31

Notes: Both groups experienced their peak unemployment rate in April 2020.
Unemployment Rates by Sex and Age
As seen in Figure 6, unemployment rates tended to increase more for younger workers and were
higher for women early in the recession. Between February and April 2020, the rate for women
ages 16-19 increased by 25.3 percentage points to 36.3%; in contrast, the rates for men of the
same age increased by 16.2 percentage points to 28.2%. Since then, the gap between younger
30 T he number of workers working part-time for economic reasons increased from 4.4 million in February 2020 to 5.8
million in March 2021 on a seasonally adjusted basis. See https://www.bls.gov/web/empsit/cpseea07.htm.
31 See https://www.bls.gov/news.release/empsit.t15.htm for U-6 unemployment rates. U-6 is a measure of the total
unemployed, plus all persons marginally attached to the labor force, plus total employed part time for economic
reasons, as a percentage of the civilian labor force plus all persons marginally attached to the labor force. For more on
this measure, see CRS In Focus IF10443, Introduction to U.S. Econom y: Unem ployment, by Lida R. Weinstock.

men and women has reversed. The unemployment rate for teenaged men (15.4%) was higher than
the rate for teenaged women (10.7%) in March 2021. Although unemployment rates for younger
workers remain relatively high compared to older workers, the March 2021 rates for men and
women across the remaining age groups have declined to similar levels. The rate for men ages
20-24 (10.9%) was slightly higher than the rate for women of the same age (9.5%). The large
disparities observed in April 2020 between younger men and women were not observed in older
age groups, although women ages 25-54 and 55 and over had rates 1-3 percentage points higher
than their male counterparts. This relatively modest gap has since closed; the rate in March 2021
for women ages 25 to 54 (5.5%) was the same as the rate for men (5.5%), and the rate for women
ages 55 and over (4.6%) was nearly the same as that of men ages 55 and over (4.5%).

Unemployment Rates by Racial Group and Hispanic Ethnicity
As seen in Figure 7, the unemployment rates for Black, Asian, and White32 workers increased
sharply in early 2020. But whereas the unemployment rate for White workers peaked in April
2020, the rate for Black and Asian workers continued to rise through May 2020. The March 2021
rates for Black (9.6%), Asian (6.0%), and White (5.4%) workers were al higher than their

respective rates in January 2020. The rate for Black workers has declined 7.1 percentage points
since peaking in May 2020, compared to a decline of 8.9 percentage points for Asian workers and
8.7 percentage points for White workers across the same period.

People of any race can identify as being either Hispanic or non-Hispanic in the CPS. As seen in
Figure 8, Hispanic workers, like Black and Asian workers, continue to experience elevated
unemployment rates. In March 2021, non-seasonal y adjusted unemployment rates experienced
by Hispanic (8.2%) and non-Hispanic (5.7%) workers were higher than those experienced prior to
the recession. While unemployment remains elevated compared to January 2020, these rates are
much lower than the peak exhibited in April 2020. The unemployment rate for Hispanic workers
rapidly increased by 13.7 percentage points to 18.5% from February to April 2020. For non-
Hispanic workers the unemployment rate increased by 10 points to 13.6%.

Unemployment Rates by Education
In general, workers with lower levels of educational attainment have higher rates of
unemployment. This pattern has been amplified during the current recession, as seen in Figure 9.
The unemployment rate for workers with less than a high school diploma peaked in April 2020
(21.0%), which was higher than the peak for those at al other education levels. The March 2021
rate for workers with less than a high school diploma (8.2%) was also higher than the rate for al
other education levels. Workers with a Bachelor’s degree or higher, the highest educational level
classified here, had the lowest peak unemployment rate (8.4% in April 2020) and the lowest
March 2021 rate (3.7%) among al education levels.

U.S. Labor Force Participation Rate: Historical
Trends
While the unemployment rate measures the prevalence of unemployment in the labor force, it
does not consider the state of the labor force itself. When persons stop looking for work, they exit
the labor force, decreasing the number of persons who are either working or actively looking for
work. Such persons are not counted in the unemployment rate, by definition, but are an important
group to examine when evaluating unemployment. CRS therefore uses the labor force
participation rate to further contextualize unemployment rates observed during the COVID-19
pandemic. The labor force participation rate measures the percentage of noninstitutionalized
people ages 16 and older who are either looking for work, or working.33
Over much of the past two decades, the labor force participation rate has general y declined.
Following several years of modest growth through the early and mid-90s, labor force
participation rates started to plateau, hit a historical peak in April 2000 (67.3%), and then
declined. Labor force participation declined further following the Great Recession, before

stabilizing and steadily increasing starting in October 2015. This decline can be attributed to
several factors, although one prominent reason is the ongoing retirement of the baby boomer
generation.34 Despite the increase exhibited following the Great Recession, the labor force
participation rate in January 2020 (63.4%) prior to both the COVID-19 pandemic and economic
recession remained below its historical peak.
Between February 2020 and April 2020, the labor force participation rate exhibited an
unprecedented decline of 3.1 percentage points as 8.3 mil ion people left the labor force. The
participation rate partial y recovered between May 2020 and August of 2020 before stagnating. It
remains below the pre-recession rate (63.4%) in March 2021 (61.5%).

Participation
The COVID-19 pandemic affected the labor force participation rates in every major demographic
group. The analysis in this section compares the pre-recession (January 2020) labor force
participation rate to the current labor force participation rate, calculating the difference between
the two for each month between January 2020 and March 2021. Figure 11 shows the sharp
decline in the labor force participation rate for individuals ages 16 years and older between
February 2020 and April 2020. During this period, 8.3 mil ion individuals left the labor force. The
overal rate recovered between May 2020 and August 2020 before stagnating. The labor force
participation rate in March 2021 remains 1.9 percentage points below its pre-recession level.

The number of nonfarm workers on payroll further contextualizes the relatively high
unemployment rates observed during the COVID-19 pandemic. Unemployment rates and labor
force participation rates do not measure the extent of job disruption occurring during the
pandemic. By comparing the number of jobs before the recession to recent data, CRS can
evaluate the extent of job loss and put unemployment rates into a broader economic context.

Data Limitations and Caveats
National level data presented in this report are from the Current Population Survey (CPS) or
Current Employment Statistics (CES) survey and state level data are from the Local Area
Unemployment Statistics (LAUS) program. The CPS is a sample survey of about 60,000
households conducted by the Census Bureau for BLS. The CES is a sample survey of about
144,000 business and government agencies conducted by BLS. LAUS is a BLS program that
calculates state-level unemployment rates using multiple data sources, including the CPS and
CES.39
Estimates from al three sources are subject to sampling and non-sampling error.40 Sampling error
occurs when the survey sample is not representative of the underlying population, while non-
sampling error describes errors often associated with data collection.41 Sampling error is a result
of statistical theory that underlies any estimate generated through surveys. While the CPS and
CES samples are selected to be representative of the nation, the possibility remains that it does
not accurately estimate certain nationwide statistics.42 Non-sampling error refers to al sources of
39 In addition to the CPS, LAUS uses the Current Employment Statistics survey, state Unemployment Insurance claims
counts, the Quarterly Census of Employment and Wages program, and data from the Census Bureau’ s American
Community Survey and Population Estimates Program; https://www.bls.gov/lau/laumthd.htm.
40 For further discussion of error, see the “Reliability of the Estimates” section of the Employment Situation report’s
T echnical Note at https://www.bls.gov/news.release/empsit.tn.htm. For a description of LAUS estimation procedures,

Unemployment Rates During the COVID-19 Pandemic
error that are not due to sampling. They can result from incorrect or biased collection and
processing of the data. For example, non-sampling error can occur if a surveyor incorrectly
records responses or a respondent incorrectly responds to a question.
COVID 19 Pandemic-Related Data Issues
The COVID-19 pandemic increased non-sampling error in the CPS and CES due to a number of
factors. For example, BLS reported that both surveys experienced lower response rates.43 BLS
additional y noted that business closures initial y interfered with the ability for businesses to
respond to CES inquiries. (The bureau has since made statements affirming the robustness of its
CPS and CES estimates despite these lower response rates.44) Furthermore, BLS detected an error
in its CPS categorization procedures that likely underestimated unemployment early in the
recession.45 Specifical y, large numbers of workers were classified as employed but not at work
when they should have been recorded as unemployed on temporary layoff.
Per agency policy, BLS did not adjust CPS records, but it did provide adjusted estimates of the
unemployment rate. This report does not use these adjusted estimates as they are not official BLS
estimates. BLS estimated that its categorization error underestimated seasonal y adjusted
unemployment by roughly 0.9 percentage points in March 2020, 4.8 points in April, 3.1 in May,
1.2 in June, 0.9 in July, 0.7 in August, 0.4 in September, 0.3 in October, 0.4 in November, 0.6 in
December, and 0.6 in January 2021. In February 2021, the error underestimated seasonal y
adjusted unemployment by an estimated 0.5 percentage points. These estimates evaluate what the
impact would be in the worst-case scenario, as the true impact is uncertain. BLS released a
statement regarding the underestimate, noting that, “these assumptions probably overstate the size
of the misclassification error.”46 In later months, BLS made efforts to correct this classification
error during data collection and processing.47
Additional y, BLS recently identified a data processing error in the CES, which began in July
2020 but remained undetected. The error unintentional y caused some businesses to be
inappropriately included in the sample and used for estimates. BLS is resolving the issue and has
not yet released guidance on the impact of the issue on employment estimates.48
LAUS was impacted by both the low response rate and the categorization error due to its
connection with the CPS and CES. Considering that LAUS is dependent on a number of other
data sources that were impacted by COVID-19 in their own right, the net effect of the pandemic
on LAUS estimates is unknown.49

Unemployment Rates During the COVID-19 Pandemic
General Data Caveats
Other data considerations include the following:
Lack of seasonally adjusted data: Seasonal y adjusted data are published by BLS
for selected labor force indicators to better account for seasonality in the trends.50
Without seasonal adjustments, it is difficult to distinguish between trends related
to the recession and seasonal trends. Where adjusted data are not available, this
report presents unadjusted data that do not account for underlying seasonal
variation.
Reference week: In general, CPS data are collected for the calendar week
containing the 12th of the month. CES data are collected for the pay period
including the 12th of the month. This could lead to incongruity between actual
labor force conditions over the course of a month and the conditions observed, as
wel as inconsistencies between CES-reported data and CPS-reported data.
CPS and LAUS unemployment rate comparability: While the LAUS program
uses the same unemployment concepts as the CPS and uses the CPS as an input,
LAUS estimates are based on multiple sources (including administrative data).
Consequently, CPS and LAUS estimates are not directly comparable.
