Unemployment Rates During the COVID-19 
December 7, 2020 
Pandemic: In Brief 
Gene Falk, Coordinator 
The Coronavirus Disease 2019 (COVID-19)  pandemic has had a significant effect on 
Specialist in Social Policy 
unemployment in every state, industry, and major demographic group in the United States. This 
  
report provides information on which groups have experienced the largest increases in 
Jameson A. Carter 
unemployment rates since the onset of the pandemic in 2020. Young workers, women, workers 
Research Assistant 
with low educational attainment, part-time workers, and racial and ethnic minorities had 
  
relatively high unemployment rates in April. Many, but not all, of these groups had relatively 
high rates in November as well. The report also compares the overall unemployment rate during 
Isaac  A. Nicchitta 
the current recession with the unemployment rate experienced during the Great Recession. This 
Research Assistant 
report shows the following: 
  
Emma  C. Nyhof 
  The unemployment rate peaked at an unprecedented level, not seen since data collection  Research Assistant 
started in 1948, in April 2020 (14.7%) before declining to a still-elevated level in 
  
November (6.7%). 
Paul D. Romero 
  In April, every state and the District of Columbia reached unemployment rates greater 
Research Assistant 
than their highest unemployment rates during the Great Recession. 
  
  In the early months of the recession, unemployment was concentrated in industries that 
 
provide in-person services. Notably, the leisure and hospitality industry experienced an 
unemployment rate of 39.3% in April, before declining to 15.0% in November. While rates for service 
industries remain elevated, other industries with loose attachment to in -person services are now 
experiencing high rates. For example, the mining industry exhibited an unemployment rate of 19.2% in 
November, the highest observed among all industries. 
  Part-time workers experienced an unemployment rate almost twice that of their full-time counterparts in 
April (24.5% vs. 12.9%), but this gap has since effectively closed. 
  Workers without a college degree experienced worse unemployment rates in April (e.g., 21.2% for workers 
with no high school degree) than workers with a Bachelor’s degree or higher (8.4%). The gap between 
educated and less-educated workers remained in November. 
  Teenaged women experienced an unemployment rate of 36.6% in April, and teenaged men, 28.6%; 
compared with 13.7% for women and 12.1% for men ages 25-54. The gap between men and women has 
since narrowed overall, but young workers are still experiencing relatively high rates of unemployment. 
  Racial and ethnic minorities had relatively high unemployment rates in April (16.7% for Black workers 
compared to 14.2% for White workers, and 18.9% for Hispanic workers compared to 13.6% for non-
Hispanic workers), and these gaps persisted in November.

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 spike in unemployment 
coincided with various 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.3 Although unemployment rates have declined since April, the November rate 
(6.7%) remains almost twice as high as the rate observed during February (3.5%).  
This report discusses recent unemployment rate patterns at the national and state levels using 
Bureau of Labor Statistics (BLS) data. The two primary sources are the Current Population 
Survey (CPS) and the Local Area Unemployment Statistics (LAUS) program. In addition to the 
usual caveats about estimates (see “General Data Caveats”), there were additional data chal enges 
caused by the COVID-19 pandemic (see “COVID-19 Related Data Issues”). 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.4 This 
report general y finds the following: 
  The unemployment rate peaked at a level not seen since data collection started in 
1948, in April  2020 before declining to a stil -high level in November. 
  In April, every state and the District of Columbia reached unemployment rates 
greater than their highest unemployment rates during the Great Recession.  
  Unemployment during the current recession is concentrated among workers who 
were last employed in industries that provide in-person services and among 
young workers, women, workers with low educational attainment, part-time 
workers, and racial and ethnic minorities. 
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 limiting contact among individuals and in 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 rate (10.3 percentage points) from February to

April 2020.5 Following April, the rate declined rapidly (8 percentage points from April to 
November 2020) as temporarily furloughed workers returned to work. Despite these rapid 
declines, the November unemployment rate persisted at a high level (6.7%). The share of workers 
on furlough has declined since peaking in April, while the share of permanently laid off workers 
has steadily increased and has now passed the number furloughed for the first time since March 
2020.6 The Congressional Budget Office (CBO) and the Federal Reserve have projected that 
elevated unemployment rates over 6% wil  persist over the next three years.7

Comparing the Great Recession and the COVID-19 Recession 
During the Great Recession, the unemployment rate increased from 5% 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% 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, peaked8 at 14.7% in April, and then fel  to 6.7% in November. The

COVID-19 Recession: Unemployment Trends 
The COVID-19 pandemic has affected the unemployment rates for every state, industry, and 
major demographic group. In the early stages of the current recession, unemployment rates 
disproportionately increased in industries delivering in-person services. Some demographic 
groups are overrepresented in such industries, contributing to higher rates for those workers.10

state was immune from economic damage early in the pandemic.11 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,12 individual fears of contracting COVID-19 causing declines in personal 
consumption,13 and the implementation of stay-at-home orders and business closure policies.14

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 November 2020 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 September, 
the five states with the highest unemployment rates were Hawai  (14.3%), Nevada (12.3%), New 
York (9.6%), Louisiana (9.4%), and California (9.3%). The states with the lowest unemployment 
rates in October were Nebraska (3.0%), Vermont (3.2%), South Dakota (3.6%), Iowa (3.6%), and 
Utah (4.1%). 
Unemployment Rates by Industry  
Workers whose last job was in the leisure and hospitality industry experienced a higher peak in 
unemployment (39.3% in April 2020) than did workers who were previously employed in any 
other industry; they also had the second highest unemployment rate in November 2020 (15.0%). 
However, elevated unemployment rates are not constrained to industries providing in-person 
services. Workers whose last job was in the mining or extraction industry have experienced 
steadily increasing unemployment since the onset of the recession; in November they exhibited 
the highest rate among al   workers across industries (19.2%). The lowest November rates were 
among workers whose last job was in the government (3.4%) or financial activities (3.5%) 
industries. These two industries have had unemployment rates below 15% from January through 
November.15 Within industries, some workers were more likely to lose their jobs than others. For 
example, recent studies suggest that low-wage workers in the leisure and hospitality industry and 
other services industries experienced disproportionately large employment losses.16 
Figure 4 displays the unemployment rate data for industries while indicating whether the change 
from 2019 to 2020 in a given month is statistical y significant.17 CRS chose to compare 2019 and 
2020 because of a lack of seasonal y adjusted data. Without seasonal adjustments, it is difficult to 
determine whether unemployment trends are related to the recession or to seasonal trends. This 
report attempts to minimize seasonal influences (for non-adjusted data) by comparing year-over-
year estimates for each month. For example, the figure shows that over the course of the current 
recession, the unemployment rate steadily declined for agricultural workers (before increasing as 
winter approached) and steadily increased for mining and extraction workers. However, the 
changes in unemployment rates for agricultural workers are not considered statistical y significant 
when tested against the prior year of data, while increases for mining and extraction workers are 
statistical y significant. 
                                              
15 T he third lowest November 2020 unemployment rate was in the education and health services sector (3.7%). T hese 
data are not seasonally adjusted  and do not account for the likely seasonal variation in employment within the 
education and health services sector.

17 BLS  publishes  a series  of formulas used  to produce standard errors for unemployment rates, f rom which they can 
calculate confidence intervals to determine whether a year -over-year difference is statistically significant. CRS  used 
these formulas to calculate significance at the 95% confidence level. Bureau  of Labor Statistics, “Calculating 
Approximate Standard Errors and Confidence Intervals for Current Population Survey Estimates,” Washington, DC,

Unemployment Rates During the COVID-19 Pandemic: In Brief 
 
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 (12.9% in April). For the first time since the onset of the 
pandemic, the unemployment rate for part-time workers in November 2020 (5.9%) was less than 
the unemployment rate for full-time workers (6.8%). Although part-time workers experienced 
worse impacts early in the recession than full-time workers, this gap has effectively closed. 
There are a few reasons why part-time workers’ apparent recovery since April may not reflect the 
economic realities they face. First, the gap between full- and part-time workers may have 
narrowed because workers with part-time jobs are leaving the labor force. It is unclear whether 
that is the case, though labor force participation rates have declined since March. Additional y, 
workers who normal y would be working full-time may be working part-time for economic 
reasons. This could reduce the unemployment rate among part-time workers. BLS has observed 
that during the current recession, measures of labor underutilization, including workers who are 
part-time due to economic reasons, have remained elevated.18

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 25.8 percentage points to 36.6%; in contrast, the rates for men of the 
same age increased by 16.4 percentage points to 27.6%. Since then, the gap between men and 
women has narrowed. Although unemployment rates for younger workers remain relatively high 
                                              
18 See  https://www.bls.gov/news.release/empsit.t15.htm for U-6 unemployment rates, 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 percent age 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.

compared to older workers, the November rates for men and women across age groups have 
declined to somewhat similar levels. The unemployment rate for teenaged men (15.2%) was 
higher than the rate for teenaged women (12.8%) in November. The rate for men ages 20-24 
(11.7%) was slightly higher than the rate for women of the same age (9.3%). The large disparities 
observed in April  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 high than their male 
counterparts. This relatively modest gap has since narrowed; the rate in November for women 
ages 25 to 54 (5.8%) was similar to that of men (6.3%), as was the rate for women ages 55 and 
over (5.8%) compared to men (5.8%).

Unemployment Rates by Racial Group and Hispanic Ethnicity 
As seen in Figure 7, the unemployment rates for Black, Asian, and White19 workers increased 
sharply in early 2020. But whereas the unemployment rate for White workers peaked in April, the 
rate for Black and Asian workers continued to rise through May. The November rates for Black 
(10.3%), Asian (6.7%), and White (5.9%) workers were al  higher than their respective rates in 
February 2020. The rate for Black workers has declined 6.5 percentage points since peaking in 
May, compared to a decline of 8.3 percentage points for Asian workers and 6.5 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, have experienced strong negative 
outcomes during the current recession. For Hispanic workers, unemployment increased by 13.7 
percentage points to 18.9% from February to April 2020. For non-Hispanic workers the 
unemployment rate increased by 10 points to 13.6%. These conditions have partial y improved, as 
Hispanic workers experienced an unemployment rate of 8.3% in November, compared to 6% for 
non-Hispanics.

Notes: Due to the lack of seasonal adjustment for these data, the 2020 unemployment rates for the Hispanic 
and non-Hispanic groups are compared to their non-seasonal y adjusted values from 2019. Statistical significance 
is not calculated because BLS does not provide formula  parameters for non-Hispanic workers. 
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 
(21.2%), which was higher than the peak for al  other education levels. The November rate for 
workers with less than a high school diploma (9%) 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) and the lowest November 
rate (4.2%) among al  education levels.

Data Limitations and Caveats 
National level data presented in this report are from the CPS and state level data are from the 
LAUS program. The CPS is a sample survey of about 60,000 households conducted by the 
Congressional Research Service 
10 
Unemployment Rates During the COVID-19 Pandemic: In Brief 
 
Census Bureau for BLS. LAUS is a BLS program that calculates state-level unemployment rates 
using multiple  data sources, including the CPS.20 
Both the CPS and LAUS estimates are subject to sampling and non-sampling error.21 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.22 Sampling error is a 
result of statistical theory that underlies any estimate generated through surveys. While the CPS 
sample is selected to be representative of the nation, the possibility remains that it does not 
accurately estimate certain nationwide statistics.23 Non-sampling error refers to al  sources of 
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 Related Data Issues 
The COVID-19 pandemic increased non-sampling error in the CPS due to a number of factors. 
For example, BLS reported that the survey experienced lower household response rates.24 (The 
bureau has made statements affirming the robustness of its estimates despite these lower response 
rates.25) Furthermore, BLS detected an error in its categorization procedures that likely 
underestimated unemployment early in the recession.26 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. 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, and 0.4 in 
November. 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.”27 In later months, BLS 
made efforts to correct this classification error during data collection and processing.28 
LAUS was impacted by both the low response rate and the categorization error due to its 
connection with the CPS. Considering that LAUS is dependent on a number of other data sources 
                                              
20 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.

T echnical Note at https://www.bls.gov/news.release/empsit.tn.htm. For a description of LAUS  estimation procedures,

28 Among other protocols, the Census Bureau  monitored survey resp onses in August  and marked those they felt could 
be misclassified.  T hese responses were  then re-evaluated. For more on BLS  and Census  efforts to reduce the 
misclassification, see https://www.bls.gov/covid19/employment -situation-covid19-faq-august-2020.htm#ques9.

Unemployment Rates During the COVID-19 Pandemic: In Brief 
 
that were impacted by COVID-19 in their own right, the net effect of the pandemic on LAUS 
estimates is unknown.29 
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.30 
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 compares year-over-year estimates to minimize seasonal influences.  
  Reference week: In general, CPS data are collected for the calendar week 
containing 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. 
  CPS and LAUS 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. 
  Statistical significance: CRS used BLS formulas to calculate year-over-year 
statistical significance in changes in monthly data. As a tool, statistical 
significance does not guarantee that year-over-year changes were meaningful.
