Current population survey (US)

The current population survey (CPS)[1] is a statistical survey conducted by the United States Census Bureau for the Bureau of Labor Statistics (BLS). The BLS uses the data to provide a monthly report on the Employment Situation.[2] This report provides estimates of the number of employed people and the number of unemployed people in the United States. The monthly unemployment rate is also computed from the data collected from the Current Population Survey. A readable Employment Situation Summary[3] is provided monthly. Available annual estimates include employment and unemployment in large metropolitan areas. In addition, private think tanks and other organizations use the CPS data for their own research.

The CPS began in 1940, and responsibility for conducting the CPS was given to the Census Bureau in 1942.[4] In 1994 the CPS was redesigned. CPS is a survey that is: employment-focused, enumerator-conducted, continuous, and cross-sectional. CPS is a monthly survey of about 60,000 households. The BLS increased the sample size by 10,000 as of July 2001.[5] The sample represents the civilian noninstitutional population. The survey asks about the employment status of each member of the household 15 years of age or older as of the calendar week containing the 12th day of the month.[6] Based on responses to a series of questions on work and job search activities, each person 16 years and over in a sample household is classified as employed, unemployed, or not in the labor force.

Methodology

Approximately 60,000 households are eligible for the CPS. Sample households are selected by a multistage stratified statistical sampling scheme.[7] A household is interviewed for 4 successive months, then not interviewed for 8 months, then returned to the sample for 4 months after that. An adult member of each household provides information for all members of the household.

As part of the demographic sample survey redesign,[8] the CPS is redesigned once a decade, after the decennial census. The most recent CPS sample redesign began in April 2014.[9]

Employment classification

Unemployment rate as a percentage of the civilian labor force in the United States according to the U.S. Bureau of Labor Statistics showing the variation across the states[10]

People are classified as employed if they did any work at all as paid employees during the reference week; worked in their own business, profession, or on their own farm; or worked without pay at least 15 hours in a family business or farm. People are also counted as employed if they were temporarily absent from their jobs because of illness, bad weather, vacation, labor-management disputes, or personal reasons.

People are classified as unemployed if they meet all of the following criteria:

The unemployment data derived from the household survey in no way depend upon the eligibility for or receipt of unemployment insurance benefits.

Those who are not classified as employed or unemployed are not counted as part of the labor force. These people —those who have no job and are not looking for one— are counted as "not in the labor force." Many who are not in the labor force are going to school or are retired. Family responsibilities keep others out of the labor force. “Discouraged workers" are a subset of those who are "not in the labor force".[11]

1994 revisions

As a result of research that started in 1986, a complete overhaul of how the CPS was administered and what type of questions were asked occurred.[12] Prior to 1994, the alternate measures of unemployment had different names because the BLS drastically revised the questions in the CPS and renamed the measures: U3 and U4 were eliminated; the official rate U5 remained the same measure but was renamed U3; U6 and U7 were revised and renamed U5 and U6.[13]

CPS alternate measures of unemployment before 1994:

CPS alternate measures of unemployment after 1994:

Marginally attached workers are persons who currently are neither working nor looking for work but indicate that they want and are available for a job and have looked for work in the recent past. In addition, marginally attached workers have actively sought work in the past 12 months (e.g. they replied to a "wanted" ad) but have not actively sought work in the past 4 weeks.

Discouraged workers, a subset of the marginally attached, have given a job-market related reason for not currently looking for a job (e.g. they believe that no work was available). This group is about 50 percent smaller than the marginally attached group."[14]

Persons employed part-time for economic reasons are those who want and are available for full-time work but have had to settle for a part-time schedule.

Data available

The CPS reports:

The survey also reports the labor force participation rate, which is the labor force as a percentage of the population, and the ratio of the employed to the total population of the United States.

Although the primary purpose of the CPS is to record employment information, the survey fulfills a secondary role in providing demographic information about the United States population. CPS microdata for the period since 1962 are freely available through the Integrated Public Use Microdata Series.

CPS Annual Social and Economic Supplement (ASEC)- the March Supplement

Since 1948, the CPS has included supplemental questions (at first, in April; later, in March) on income received in the previous calendar year, which are used to estimate the data on income and work experience. These data are the source of the annual Census Bureau report on income, poverty, and health insurance coverage.

Other supplement topics (some in different months) include after-tax money income, benefits that are not cash, displaced workers, job tenure, occupational mobility, temporary work, adult education,volunteering, tobacco use, food availability, fertility, veteran information, and other related topics.
