How to Calculate the Actual Rate of Unemployment

The unemployment rate stands as a widely referenced economic indicator, offering insights into the health of the economy and job availability. Understanding how this metric is determined provides valuable context for interpreting economic news and assessing labor market conditions. This rate influences policy decisions and reflects the utilization of labor resources.

Defining Labor Market Status

The Bureau of Labor Statistics (BLS) categorizes the adult civilian noninstitutional population into three groups. Individuals are “Employed” if, during the survey reference week, they worked at least one hour for pay or profit, or 15 or more hours as an unpaid worker in a family business. This category also includes those temporarily absent from their jobs due to reasons like illness, vacation, or bad weather, but who still had a job to which they would return.

Individuals are classified as “Unemployed” if they did not have a job during the survey reference week, were available for work, and actively sought employment within the past four weeks. Active job-seeking includes submitting applications, attending interviews, or other direct efforts to find work.

The third category, “Not in the Labor Force,” includes people who are retired, full-time students not seeking work, homemakers, or those unable to work due to disability.

The Official Unemployment Rate Calculation

The official unemployment rate is derived from these labor market classifications. It represents the percentage of the labor force that is unemployed. The formula divides the total number of unemployed individuals by the civilian labor force, then multiplies by 100 to express it as a percentage.

The civilian labor force represents the sum of all employed and unemployed individuals aged 16 and older who are not institutionalized or on active military duty. For instance, if a nation has 5 million unemployed individuals and a civilian labor force of 150 million, the unemployment rate would be approximately 3.3 percent.

The Bureau of Labor Statistics (BLS) uses this definition of unemployment, known as U-3, as its official measure. This consistent methodology allows for monthly comparisons and analysis of labor market trends. The official rate aims to capture the current unmet demand for jobs within the active labor pool.

Data Collection for Unemployment Statistics

The raw data necessary for calculating the official unemployment rate is meticulously collected each month through the Current Population Survey (CPS). This extensive household survey is jointly conducted by the U.S. Census Bureau and the Bureau of Labor Statistics (BLS). The CPS is not based on unemployment insurance claims, which only cover a subset of the unemployed, but rather on a direct survey of households.

The survey targets a scientifically selected, multi-stage probability sample of approximately 60,000 to 74,000 assigned housing units across the United States. From these, interviews are typically completed for about 54,000 to 62,000 eligible households each month, gathering information from around 105,000 individuals aged 16 and older. This large sample size ensures the data is representative of the civilian noninstitutional population.

Interviews are conducted through a combination of live telephone and in-person interactions. Households remain in the sample for four consecutive months, then rotate out for eight months, and return for another four consecutive months. This rotation system helps to maintain continuity in the data while reducing the burden on participating households, providing a consistent stream of information on employment status and other labor force characteristics.

Broader Measures of Unemployment

While the official unemployment rate (U-3) is a widely reported statistic, it does not encompass all forms of labor underutilization. The Bureau of Labor Statistics publishes several alternative measures, designated U-1 through U-6, to provide a more comprehensive view of the labor market. These broader measures account for individuals who face employment challenges but are not captured by the strict definition of official unemployment.

The U-6 measure is considered the most expansive of these alternatives, offering a more complete picture of underemployment. It includes all individuals counted in the official unemployment rate (U-3). Additionally, U-6 incorporates “marginally attached workers,” who want a job, have looked for work in the past 12 months, and are available for employment, but have not actively searched in the last four weeks. This group includes “discouraged workers,” who specifically stopped looking due to the belief that no jobs are available.

Finally, the U-6 measure also adds persons employed part-time for economic reasons. These are individuals who would prefer and are available for full-time work but are working reduced hours due to business conditions or the inability to find full-time employment. By including these various categories of underutilized labor, the U-6 rate offers a more detailed and often higher estimate of job market challenges than the official U-3 rate.
