How to Calculate the Labor Force Participation Rate

To calculate the labor force participation rate, divide the labor force by the civilian noninstitutional population aged 16 and older, then multiply by 100. The labor force is everyone who is either employed or actively looking for work. The civilian noninstitutional population is everyone 16 or older living in the 50 states or D.C., minus active-duty military and people in institutions like prisons or nursing homes. In January 2026, that math produced a national rate of 62.5%.¹

The formula itself is simple. The work is in defining the two numbers correctly.

The Formula

The Bureau of Labor Statistics defines the participation rate as:

(Labor Force ÷ Civilian Noninstitutional Population) × 100²

The result is a percentage. Everything else is a question of who belongs in the top number and who belongs in the bottom.

The Denominator: Civilian Noninstitutional Population

The denominator is the civilian noninstitutional population. That means everyone aged 16 and older living in the 50 states and the District of Columbia, with two groups removed: active-duty members of the Armed Forces, and people living in institutions such as prisons, nursing homes, and residential care facilities.²

The number itself comes from the Current Population Survey, a monthly survey of roughly 60,000 households conducted by the Census Bureau for BLS.³ The survey does not count every person; it produces an estimate. For January 2026, that estimate put the civilian noninstitutional population at about 275.0 million.¹

The Numerator: The Labor Force

The numerator is the total labor force, which is the sum of two groups: employed people and unemployed people who are actively searching for work. Anyone who does not fit either definition is “not in the labor force” and does not appear in the top of the fraction at all.

Who Counts as Employed

The BLS definition of employment is broader than most people expect. You count as employed if you did any paid work at all during the survey reference week, even a single hour. You also count if you worked at least 15 hours without pay in a business run by a family member.² And if you had a job but missed the entire week because of vacation, illness, a labor dispute, or parental leave, you still count as employed. What matters is whether you have a job to return to, not whether you clocked in that particular week.⁴

Who Counts as Unemployed

“Unemployed” has a strict technical meaning in this calculation. To count, a person must meet all three conditions: no employment during the reference week, availability to work, and at least one active job-search effort in the prior four weeks.²

Active efforts include contacting employers, going on interviews, submitting applications, and reaching out to employment agencies or personal contacts for leads. Passive steps do not count. Scrolling through job listings without applying, or attending a training course, fails the test because neither activity could directly result in a job offer.⁵ This distinction is what pushes many non-working people out of the numerator entirely.

Who Falls Out of the Rate Entirely

Everyone who is neither employed nor meets the strict definition of unemployed is classified as “not in the labor force.” That group includes retirees, full-time students who are not job hunting, people caring for family members, and anyone else who is not working and not actively searching.⁶ They do not appear in the numerator, though they do appear in the denominator, which is what makes the participation rate move.

One subgroup within “not in the labor force” is worth naming because it is easy to overlook. BLS calls people “marginally attached” if they want a job, are available to work, and have searched at some point in the past 12 months, but have not actively looked in the last four weeks. Within that group, “discouraged workers” are the ones who stopped looking specifically because they believe no suitable jobs exist for them.² Neither the marginally attached nor discouraged workers appear in the standard participation rate. If you see the rate fall, some of the drop may be people giving up rather than people retiring comfortably.

A Worked Example

Plugging real numbers into the formula makes it concrete. For January 2026, BLS reported a civilian labor force of about 171.9 million and a civilian noninstitutional population of about 275.0 million.¹

Step 1. Divide the labor force by the eligible population:

171.9 million ÷ 275.0 million = 0.6251

Step 2. Multiply by 100 to convert to a percentage:

0.6251 × 100 = 62.5%

Read plainly, that means about 63 of every 100 working-age civilians outside institutions are either working or actively trying to find work.⁷ The remaining 37 are outside the labor market.

Small movements represent large numbers of people. A single tenth of a percentage point at these population levels corresponds to roughly 275,000 individuals entering or leaving the labor force, which is why analysts look for sustained trends rather than reacting to any one month.

Seasonally Adjusted or Unadjusted

The headline participation rate BLS publishes each month is seasonally adjusted. Predictable patterns such as summer teenage hiring, holiday retail staffing, and school-year enrollment swings would otherwise distort month-to-month comparisons. Seasonal adjustment removes those recurring fluctuations so the underlying trend is easier to read.⁸

BLS also publishes unadjusted data. If you are comparing the same month across different years, unadjusted figures work fine, because the seasonal effects are roughly the same each time. If you are comparing January to July within the same year, use the adjusted version. Most news coverage relies on seasonally adjusted numbers by default.

A Note on Related Metrics

The participation rate answers one specific question: what share of the working-age population is in the labor force. It does not tell you how many people are actually working (that is the employment-population ratio, which uses the same denominator but counts only the employed in the numerator).² It also does not capture underemployment or people who have drifted just outside the labor force; that is what the U-6 rate is for. If you need those measures, do not try to derive them from the participation rate. They come from separate calculations.

Where to Pull the Numbers

BLS releases the participation rate on the first Friday of every month as part of the Employment Situation report. Current figures and historical charts are on the BLS labor force participation page at bls.gov. Detailed breakdowns by age, gender, race, and education come from the Current Population Survey tables at bls.gov/cps. All of the underlying data is free to download, so if you want to redo the calculation for a specific month or a specific subgroup, the inputs are available directly from the source.
