Who is Included in Oregon’s Unemployment Rate Calculation?

by Tracy Morrissette

August 2, 2023

The unemployment rate is a general measure of labor market conditions in a geographical area. This article focuses on the specific components of the civilian noninstitutional population (CNP) included in and excluded from the definition of the unemployment rate. These segments of the population are defined by the Bureau of Labor Statistics (BLS).

Who’s Factored into the Unemployment Rate Calculation?

Simply stated, segments of the population in the table under the heading “included” are factored into the unemployment rate calculation while those under the heading “excluded” are not. Data on some of the groups listed in the table are published by BLS, while others (many of the groups in the “excluded” column) are not published. For this reason, the table is an oversimplification. In reality, the classification scheme is more complex and there are procedures in place to deal with gray areas.

Finding More Detailed Labor Force Data

The line drawn between included and excluded in the table has led some to argue that the unemployment rate is either too specific or too broad a measure and thus fails to capture the “true” state of the labor market. The version of the unemployment rate that shows up in press headlines is one general view of the labor market. More detailed labor market data are published by BLS that provide a closer look at labor market conditions. In addition to the headline unemployment rate, detailed data about the characteristics of the CNP are published for the United States each month. Among the details are data on those not in the labor force and demographic characteristics of the labor force.

Detailed labor market data for Oregon are only published annually on the BLS website. One source is the Geographic Profile of Employment and Unemployment (GP). GP data are based on annual averages from the Current Population Survey (CPS), most recently for 2022, and available on the BLS website at: https://www.bls.gov/opub/geographic-profile/. Although not as detailed as the GP reports, another source of detailed data are available for 2022 for states at: https://www.bls.gov/lau/table14full22.pdf. Oregon data are on page 49 of this report. These and other reports are located under the Annual Average section of the Local Area Unemployment Statistics (LAUS) home page at: https://www.bls.gov/lau/.

The Civilian Labor Force

The CNP is comprised of all persons 16 and older, excluding the institutional population (e.g., penal and mental facilities or homes for the aged) and those on active duty in the U.S. Armed Forces. The CNP is the population base for the derivation of the labor force data. Oregon’s 2022 annual average CNP was around 3.5 million.

The CNP consists of two groups: those in the labor force and those not in the labor force. Individuals in the labor force either have a job (i.e., are employed) or are actively seeking one (i.e., are unemployed). In 2022, close to 2.18 million Oregonians, or more precisely 62.8% of the CNP based on unrounded figures, were in the civilian labor force. Those not in the labor force are without employment and not engaged in an active job search. Around 1.3 million Oregonians were not in the labor force in 2022.

Among individuals not in the labor force are those generally described as having some “marginal attachment” to it. The marginally attached have indicated that they want a job, are available to work, and have looked for work sometime during the prior 12 months. These individuals are not considered unemployed, however, because they did not actively search for work during the four weeks preceding the CPS reference week (the week of each month containing the 12th day). “Discouraged workers” are a subset of the marginally attached. They are not looking for work because they believe there are no jobs available or there are none for which they qualify. For Oregon in 2022, of the 1.3 million who were not in the labor force, about 1.8% were marginally attached and 0.3% were discouraged workers. Nationally in 2022, 99,686,000 people were not in the labor force. Among these individuals, 1,484,000 (about 1.5%) were marginally attached and 407,000 (about 0.4%) were discouraged workers.

Total Employment

The employed consist of two main groups. The first group is all civilians who, during the survey week, did at least one hour of work as paid employees, worked in their own business, profession, or on their own farm, or who worked 15 hours or more as unpaid workers in an enterprise operated by a member of the family. The second group includes those who were not working but had jobs from which they were temporarily absent. Reasons for temporary absence from work include illness, inclement weather, vacation, childcare problems, maternity or paternity leave, labor-management disputes, job training, or other family or personal reasons, whether they were paid for the time off or seeking other jobs. In 2022, approximately 4.8% of Oregon’s 2.1 million employed were temporarily away from their jobs. Each employed person is counted only once each month, even if he or she holds more than one job.

A full-time worker is defined as an individual who usually works 35 or more hours per week. If the individual has more than one job, then the hours at all jobs are aggregated to determine the usual full- or part-time work status. A part-time worker is defined as an individual who usually works from one to 34 hours per week. Particular attention should be paid to the word “usually” in both the full- and part-time definitions. During the reference week, a worker who usually works 40 hours per week may actually work only 25 hours. This worker, however, would be classified as a full-time worker since he or she usually works 40 hours. In 2022, about 81% of Oregon’s employed were usually working full time, while about 19% were usually part-time workers.

Individuals working part time for economic reasons, also known as “involuntary part-time,” have indicated they are available for full-time work. However, for economic reasons such as slack work, unfavorable business conditions, inability to find full-time work, and seasonal declines in demand, these people are working part time. Those at work part time for economic reasons comprised about 2.4% of Oregon’s employed in 2022. Likewise, there are those who work part time for noneconomic reasons, such as illness or other medical limitation, childcare problems or other family or personal obligations, school or training, and retirement or social security limits on earnings. Those at work part time for noneconomic reasons comprised about 23.7% of employment in Oregon in 2022.

Individuals not considered employed are persons whose only activity consists of working in their own homes, doing activities such as painting, repairing, cleaning, or other home-related work. Also excluded from the total employment number are those only doing volunteer work for religious, charitable, or similar organizations. Those only caring for children or elderly are excluded as well.

Total Unemployment

Total unemployment is composed of all persons who were not employed during the CPS reference week but were available for work and had made specific efforts to find employment some time during the four-week period ending with the CPS reference week. Individuals waiting to be recalled to a job from which they had been laid off, known as “persons on layoff,” do not need to be looking for work to be classified as unemployed.

To be considered unemployed, one must make specific efforts to find employment. Depending on the job search method used, an individual without employment may be considered either unemployed or not in the labor force. Active job search methods are those that have the potential to result in a job offer without any further action on the part of the job seeker. Examples of active job search methods include going to an employer directly, going to a public or private employment agency, seeking assistance from friends or relatives, and placing or answering ads. Passive methods, which do not qualify as a job search, include reading (as opposed to answering or placing) help wanted ads and taking a job training course. Individuals using active job search methods are considered unemployed, while individuals using passive job search methods are classified as not in the labor force.

The five major categories of unemployed persons are grouped by their status at the time they became unemployed:

  • Job losers: This is a group composed of (a) those permanently laid off whose employment ended involuntarily and who immediately began looking for work, and (b) those temporarily laid off from a job to which they expect to be recalled.
  • Job leavers: Persons who have quit or otherwise terminated their employment voluntarily and have begun to look for work.
  • Persons who have completed temporary jobs, who began looking for work after their jobs ended.
  • Re-entrants: Persons who previously worked but were outside of the labor force before beginning their job search.
  • New entrants: Persons who never worked before and who are entering the labor force for the first time.

In 2022, 43% of Oregon’s approximately 92,000 unemployed were job losers and persons who completed temporary jobs, 18% were job leavers, 31% were re-entrants, and 8% were new entrants.

The Unemployment Rate

Now that the labor force concepts have been explained in some detail, those measured in the unemployment rate can be seen by looking at this equation:

unemployment rate = (unemployed / civilian labor force) * 100

The unemployment rate is a measure of those who are without employment and are taking active steps to find employment, shown as a ratio of all those who are in the labor force (either employed or unemployed). Being included in the unemployment rate calculation can be thought of as having an attachment to the labor market – either one has a job or has actively sought to obtain one in the past four weeks. In the 2022 detailed CPS reports for Oregon, the unemployment rate was 4.2%.

A Note on Using the Detailed State Labor Force Data

GP and CPS annual employment and unemployment data for states will not be identical to the annual average estimates based on the official labor force values published each month. The official annual averages for Oregon were developed using time series models of survey-based data, whereas the CPS annual tables reflect averages of survey-based data.

Which data series should be used for analysis? The answer depends on the purpose of the analysis. If an analyst is tracking Oregon’s unemployment rate over time, then the official data should be used. On the other hand, if an analyst is focusing on detailed labor force information within a given year, then GP and CPS annual data are the best option.

Annual average unemployment rates for 2022 from the two data sets did not differ in a statistically detectable way. Rounded to the customary nearest one-tenth, Oregon’s CPS annual average unemployment rate was 4.2%, where the official annual average unemployment rate was reported at 4.2% as well. The CPS annual average unemployment rate had a 90% confidence interval of 3.6% to 4.8%, where the official unemployment rate had a 90% confidence interval of 3.6% to 4.7%. This error range is based on unrounded data. Annual averages from both data sets are not always equal, but usually are close.


This article provides a general overview of the population segments included in Oregon’s unemployment rate calculation. The unemployment rate is a useful indicator of labor market conditions in a geographical area. However, it provides only one perspective of a complex and dynamic job market. For the nation, greater detailed data series provide more information about the labor market each month. This labor force detail, however, is not published each month for Oregon. The only labor force data published for Oregon by month are the civilian labor force, labor force participation rate, total employment, employment-to-population ratio, total unemployment, and the unemployment rate. More detailed information about Oregon’s CNP is published annually on the BLS-LAUS website.
