I am replying to a message that was forwarded to the program office within the Bureau of Labor Statistics (BLS) that handles requests relating to the Current Population Survey (CPS). The CPS is a monthly survey of approximately 60,000 households and is a primary source of U.S labor force data.
To answer your question, I’ll explain how BLS measures employment. Employment data are published every month in the Employment Situation Summary news release and come from two surveys. One survey is conducted among U.S. households and measures the number of people with jobs. This is the household hold survey, or the CPS. In the CPS, employment is defined as:
Persons 16 years and over in the civilian noninstitutional population who, during the reference week, (a) did any work at all (at least 1 hour) as paid employees, worked in their own business, profession, or on their own farm, or worked 15 hours or more as unpaid workers in an enterprise operated by a member of the family, and (b) all those who were not working but who had jobs or businesses from which they were temporarily absent because of vacation, illness, bad weather, childcare problems, maternity or paternity leave, labor-management dispute, job training, or other family or personal reasons, whether or not they were paid for the time off or were seeking other jobs. Each employed person is counted only once, even if he or she holds more than one job. Excluded are persons whose only activity consisted of work around their own house (painting, repairing, or own home housework) or volunteer work for religious, charitable, and other organizations.
Respondents in the CPS are directly asked whether workers in the household have more than one job. Thus allowing multiple job holders to be counted.
The other survey, the Current Employment Statistics (CES) Survey is conducted among firms in the U.S. and is also known as the payroll or establishment survey. Employment in the CES is measured by the number of individuals on a company’s payroll.
An important difference between the surveys is that the household survey provides a count of employed persons; whereas, the CES, the establishment survey, provides a count of JOBS. This difference refers to how multiple jobholders are treated by each survey. The establishment survey counts jobs because, for example, if one person worked two jobs, that person would be counted twice in the establishment survey because he or she would appear on both establishments’ payroll records. However, in the household survey
(CPS) the person would be counted as one employed person because he or she did some work during the reference week.
Therefore, the unemployed person who finds a job with two employers, as you noted in your message, would be counted differently in each survey. In this case, the person would be counted twice in the CES for each job in the bank and the taxi. Yet, the individual would count as one employed person in the CPS regardless of the number of hours worked.
The following web site provides further information regarding the two surveys and their differences. http://www.bls.gov/cps/ces_cps_trends.pdf
On the topic of the number of jobs created during any time period, neither survey counts the number of jobs gained or lost each month. Rather, both measures give the overall level of employment. What is commonly referred as “job creation” is actually the net change in employment level over a given time period.
I hope this information is helpful and if you have other questions feel free to contact me.
