The labor force participation rate (LFPR) is the share of the civilian, noninstitutional working-age population that is in the labor force, meaning people who either have a job or are actively looking for one. In the United States, the Bureau of Labor Statistics (BLS) defines working age as 16 and older. The labor force formula is the number of employed plus unemployed people. The participation rate divides that total by the eligible population and multiplies by 100.

Participation measures how much of the potential workforce is engaged with the job market at all. The unemployment rate measures only how many of the engaged lack work, so the two figures can move in opposite directions.

What Is the Labor Force Participation Rate?

Three groups make up the population that matters for the calculation.

1. Employed: people who did any work for pay or profit during the survey reference week, including part-time and temporary work. Self-employed people and business owners who work in their business count as employed, so they are part of the labor force. Unpaid work in a family business also counts as employment in the U.S. survey if it is done for at least 15 hours in the reference week. People with a job who were temporarily absent (vacation, illness, a labor dispute) also count as employed.
2. Unemployed: people who had no job, were available for work, and had made a specific effort to find work during the prior four weeks. People on temporary layoff who expect to be recalled are also counted as unemployed even if they are not searching.
3. Not in the labor force: everyone else in the eligible population. This group includes retirees, students who are not working or job hunting, people caring for family full time, people unable to work because of a disability, and discouraged workers who want a job but have stopped searching.

The denominator, the civilian noninstitutional population, excludes two groups entirely: active-duty members of the armed forces, and people living in institutions such as prisons, nursing homes and long-term mental health facilities. Those people are not counted as “not in the labor force.” They are left out of the calculation altogether.

How the Labor Force Participation Rate Works

Calculating Labor Force Participation Rate

The labor force participation rate formula is:

LFPR = (Employed + Unemployed) ÷ Civilian noninstitutional population × 100

Example of Labor Force Participation Rate

This is a hypothetical economy, built only to show the mechanics.

• Labor force = 118,000 + 6,000 = 124,000
• LFPR = 124,000 ÷ 200,000 × 100 = 62.0%
• Unemployment rate = 6,000 ÷ 124,000 × 100 = 4.84%
• Employment-population ratio = 118,000 ÷ 200,000 × 100 = 59.0%

Now assume 3,000 of the unemployed become discouraged and stop searching. Nobody gains or loses a job, and the population does not change.

• Labor force = 118,000 + 3,000 = 121,000
• LFPR = 121,000 ÷ 200,000 × 100 = 60.5%
• Unemployment rate = 3,000 ÷ 121,000 × 100 = 2.48%
• Employment-population ratio stays at 59.0%

The unemployment rate nearly halved, which looks like a strong improvement. But employment did not change at all. The drop in participation shows that people left the market rather than found work. This is the main reason analysts read participation alongside unemployment.

Interpreting Labor Force Participation Rate

• A rising rate can mean improving job prospects that pull people back into searching. It can also reflect social change, such as more women entering paid work, or economic pressure that pushes second earners or older people back into jobs.
• A falling rate can signal discouraged workers leaving during a downturn. It can also come from structural shifts that say little about labor demand, such as a large generation retiring or more young people staying in school.

For this reason, economists often look at participation by age group. The prime-age labor force participation rate covers people 25 to 54, an age range where retirement and schooling matter less. It filters out much of the aging effect and gives a cleaner read on whether people of normal working age are engaged with the job market.

Why Is Labor Force Participation Rate Important?

Participation shapes the economy’s capacity to produce. Labor is one of the factors of production, and output growth comes broadly from more workers, more hours, or more output per hour. A shrinking share of the population in the labor force means that, all else equal, GDP growth must lean harder on productivity.

The rate also matters for public finances. Fewer workers relative to the population means a smaller base paying payroll and income taxes while the number of people drawing retirement benefits grows. For monetary policy, participation helps gauge how much slack exists in the labor market: a low unemployment rate paired with depressed participation suggests there may be people on the sidelines who could be drawn back in, which can ease wage pressure.

Labor force participation vs. unemployment rate

These two measures use different denominators, and that difference causes most confusion.

The three are linked by an identity: employment-population ratio = LFPR × (1 − unemployment rate), with rates expressed as decimals. In the first scenario of the example, 0.62 × (1 − 0.0484) ≈ 0.59.

Discouraged workers are not part of the labor force, so they appear in neither the numerator nor the denominator of the unemployment rate. The participation rate does not “include” them either. It reflects their exit by falling. BLS also publishes broader underutilization measures, such as U-6, that add discouraged and other marginally attached workers and people working part time who want full-time work.

How the Labor Force Participation Rate Is Measured

In the U.S., the figures come from the Current Population Survey (CPS), a monthly survey of roughly 60,000 households conducted by the Census Bureau for BLS. Respondents answer questions about each household member’s age and activities during a specific reference week: whether they worked, whether they had a job they were absent from, and whether they looked for work in the past four weeks. BLS classifies each person from those answers. Respondents are not asked to label themselves “unemployed.”

BLS releases the national participation rate each month in the Employment Situation report, alongside the unemployment rate, with seasonally adjusted figures that smooth out regular patterns such as summer youth hiring. It also publishes breakdowns by sex, age, race and education. Because the CPS is a sample, monthly changes of a tenth of a percentage point or so can fall within normal sampling variation. Population controls are also updated each year, which can shift the level of the series.

Factors That Affect the Participation Rate

Economic factors

In the short run, the business cycle matters most. During recessions, the rate tends to fall as laid-off workers give up searching when jobs are scarce. During strong expansions, some of them return.

Over longer periods, industrialization tends to raise participation by creating wage jobs. Accumulated wealth can pull the other way, because households with more savings or assets have less need for every adult to work. Policy also plays a role: heavy labor market regulation and generous benefit programs may reduce participation by changing the payoff to working. Rising education levels involve an opportunity cost too: a year spent in school is a year of earnings forgone.

Social factors

Expectations about who should work have a large effect. Where married women are expected to stay home after marriage or childbirth, participation is lower. Where both parents are expected to be able to work, more people of either sex stay in the workforce. The broad entry of women into paid work in the second half of the 20th century is the clearest U.S. example.

Educational norms also matter. In groups where young people learn a trade or join a family business, workers enter the labor force in their late teens. Where a college degree is seen as necessary, many young adults stay out of the labor force, or work only part time, until their early or mid-twenties.

Demographic factors

The age structure of the population shifts the overall rate even if behavior within each age group stays the same. When a large generation reaches retirement age, the share of the 16-and-older population that is working falls mechanically. The baby boom generation is the main example in the U.S. Later generations are smaller relative to the population they replace, so retirements are not fully offset by new entrants.

Trends in the U.S. Participation Rate

The U.S. rate rose through the second half of the 20th century, driven largely by women’s growing participation, and peaked at 67.3% in April 2000. Women’s participation nearly doubled over the 50 years from 1948 to 1998, from about 32% to about 60%.

The Great Recession of 2007 to 2009 began several years of steep decline, and the rate settled around 63% by 2013. It stayed near that level until the COVID-19 pandemic, when it dropped from 63.3% to a low of 60.1% in April 2020, the sharpest fall in the series. Women’s participation fell from 58% in February 2020 to 54.6% in April 2020. The overall rate recovered gradually afterward but did not return to its pre-pandemic level.

The prime-age picture differs. According to Federal Reserve data, participation among people ages 25 to 54 peaked at 84.6% in January 1999.

Why the Labor Participation Rate Has Declined

Several forces explain the long slide since 2000:

• Population aging: The Council of Economic Advisers estimated that up to half of the drop in participation from 2007 to 2014 came from the aging of the workforce. Boomers have since been outnumbered by millennials but remain a large group moving through retirement.
• The Great Recession: Unemployment rose from about 5% to 10%. The overall jobless rate later returned to pre-recession levels, but long-term unemployment rose, and many workers who left the labor force never returned to full-time work.
• COVID-19: Shutdowns ended many in-person jobs, some people were unwilling or unable to keep face-to-face work, and others left to care for family. Women left at higher rates than men, in part because of caregiving expectations.
• College enrollment: Students participate less while enrolled. U.S. undergraduate enrollment climbed to 16.63 million in 2011, then fell to 13.28 million in 2021, so this factor has varied over time rather than pushing in one direction.

Global Labor Force Participation

The World Bank publishes participation rates using ages 15 and older, based on International Labour Organization (ILO) modeled estimates, rather than the BLS cutoff of 16. By that measure, global participation has drifted down over time: about 65% in 1991, 63% in 2010, and a pandemic low of 59% in 2020 before recovering to about 61%, its 2019 level.

Rates vary widely across countries. Some Gulf states with large migrant workforces, and many low-income economies where most adults work in agriculture or informal jobs, report very high participation. Rates are much lower in countries affected by conflict and in places where few women take part in paid work. In the World Bank’s data, the U.S. sits near the middle, slightly above the world average.

When comparing countries, use one source with one definition. Mixing a BLS figure (16+, CPS-based) with a World Bank figure (15+, modeled) can create gaps that come from method rather than economic differences.

Limitations of Labor Force Participation Rate

• It does not show job quality. A part-time worker who wants full-time hours and a full-time professional both count as one employed person.
• It mixes structural and cyclical change. A falling rate driven by retirement and one driven by discouraged workers look the same in the headline number. Age-specific and prime-age rates help separate them.
• It depends on survey answers. Classification relies on what respondents report about a single reference week, and sample estimates carry error.
• It excludes some people entirely. Active-duty military and institutionalized people are outside the denominator, so changes in those populations do not show up.
• Higher is not automatically better. A rise driven by older people returning to work because savings fell short, or a fall caused by more people choosing education, carries a different meaning than the number alone suggests.
• Informal work is hard to capture. In economies with large informal sectors, measured participation depends heavily on how surveys treat unpaid family work and subsistence activity.

FAQs

The Bottom Line

Anyone reading jobs reports or judging labor market slack should read participation alongside the unemployment rate, since a falling jobless rate can reflect people leaving the market. Prime-age and age-specific rates help separate retirement and schooling from cyclical weakness. For cross-country comparisons, stick to one source, because BLS and World Bank figures use different age cutoffs and methods.
