Technical Note The estimates in this release were obtained from the Current Population Survey (CPS), a national sample survey of about 60,000 eligible households conducted monthly for the Bureau of Labor Statistics (BLS) by the U.S. Census Bureau. The data in this release relate to the employment status of youth (16- to 24-year-olds) during the months of April-July. This period was selected as being the most representative time frame in which to measure the full summertime transition from school to work. July is the peak summer month of youth employment. Beginning in January of each year, data reflect revised population controls used in the CPS. Additional information about population controls is available on the BLS website at www.bls.gov/cps/documentation.htm#pop. If you are deaf, hard of hearing, or have a speech disability, please dial 7-1-1 to access telecommunications relay services. Reliability of the estimates Statistics based on the CPS are subject to both sampling and nonsampling error. When a sample, rather than the entire population, is surveyed, there is a chance that the sample estimates may differ from the true population values they represent. The component of this difference that occurs because samples differ by chance is known as sampling error, and its variability is measured by the standard error of the estimate. There is about a 90-percent chance, or level of confidence, that an estimate based on a sample will differ by no more than 1.6 standard errors from the true population value because of sampling error. BLS analyses are generally conducted at the 90-percent level of confidence. The CPS data also are affected by nonsampling error. Nonsampling error can occur for many reasons, including the failure to sample a segment of the population, inability to obtain information for all respondents in the sample, inability or unwillingness of respondents to provide correct information, and errors made in the collection or processing of the data. More information on the reliability of data from the CPS and estimating standard errors is available online at www.bls.gov/cps/documentation.htm#reliability. Definitions The principal definitions used in this release are described briefly below. Employed. Employed persons are all those who, during the survey reference week (which is generally the week including the 12th day of the month), (a) did any work at all as paid employees; (b) worked in their own business, profession, or on their own farm; (c) worked 15 hours or more as unpaid workers in a family member's business. Persons who were temporarily absent from their jobs because of illness, bad weather, vacation, labor dispute, or another reason also are counted as employed. Unemployed. The unemployed are those who had no employment during the reference week, were available for work at that time, and had made specific efforts to find employment sometime during the 4-week period ending with the reference week. Persons who were waiting to be recalled to a job from which they had been laid off need not have been looking for work to be classified as unemployed. Looking for full-time work refers to 35 hours or more per week; part-time work refers to fewer than 35 hours per week. Civilian labor force. This group comprises all persons classified as employed or unemployed. Unemployment rate. The unemployment rate is the number of unemployed persons as a percent of the civilian labor force. Labor force participation rate. The labor force participation rate is the labor force as a percent of the population. Employment-population ratio. The employment-population ratio is the employed as a percent of the population. Not in the labor force. Included in this group are all persons in the civilian noninstitutional population who are neither employed nor unemployed. Industry and class of worker. This information applies to the job held during the reference week. Persons with two or more jobs are classified in the job at which they worked the greatest number of hours. Beginning with data for 2020, persons are classified using the 2017 Census industry classification system. The class-of-worker breakdown assigns workers to the following categories: Private and government wage and salary workers, unincorporated self-employed workers, and unpaid family workers. Wage and salary workers. Included in this group are persons who receive wages, salary, commissions, tips, or pay in kind from a private employer or from a government entity. Self-employed workers. Included in this group are those who work for profit or fees in their own unincorporated business, profession, trade, or farm. Only unincorporated self-employed are included in the self-employed category. Self-employed persons whose businesses are incorporated are included with private wage and salary workers. Unpaid family workers. Included in this group are persons working without pay for 15 hours a week or more on a farm or in a business operated by a family member in their household.
