Current Population Survey, 2005: Unemployment Insurance (UI) Non-Filers Supplement (ICPSR 4689)

Principal Investigator(s): United States Department of Commerce. Bureau of the Census; United States Department of Labor. Bureau of Labor Statistics


This data collection is comprised of data from the January, May, July, and November iterations of the 2005 Current Population Survey (CPS). In each of these months, two sets of questions were administered: the basic CPS questions, and a supplemental survey questionnaire on the topics of unemployment insurance and unemployment compensation. The supplement interviews were conducted in two rotations of four separate months (January, May, July, and November) in 2005 then merged into one dataset.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the survey.

The supplement was designed for proxy responses, meaning a single respondent could provide answers for all eligible household members, provided the respondent was a household member and met the sampling universe criteria. The supplement was asked of persons in the labor force aged 16 years and older, who met one of the following specific labor force conditions: (1) unemployed individual on layoff, (2) unemployed job seeker who worked in the last 12 months, (3) unemployed job seeker who last worked more than 12 months ago, (4) unemployed job seeker who worked before beginning to search for a job, but responded with "refuse," "don't know," or "blank" to the CPS labor force item of when last worked, and (5) individual not currently classified as unemployed but has not worked in the last 12 months. If any person in a household was eligible for the supplement, then the entire household was included in the dataset.

The supplement contained person-level questions structured to determine whether or not an individual had applied for unemployment compensation. Individuals who had applied for compensation were asked if they had received the compensation. If they had not received any compensation, then the individuals were asked why they had not received the compensation. Data are also provided on the number of unemployed persons. Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

Geographic Coverage:    United States

Time Period:   

  • 2005

Date of Collection:   

  • 2005 (January, May, July, and November)

Unit of Observation:    individuals within housing units

Universe:    The basic CPS universe consists of all households in the civilian noninstitutional population of the United States. The supplement universe was civilian non-institutional population, age 16 and older, who had completed the CPS labor force interview and met specific conditions related to being unemployed, and whose month-in-sample was four or eight. If the household had any person eligible for the supplement, then the entire household was included in the dataset.

Data Type(s):    survey data

Data Collection Notes:

Users are strongly encouraged to refer to the User Guide (produced by the Principal Investigators), which contains not only information about the basic CPS survey, but also detailed technical documentation specific to the supplement. In particular, Attachment 8 of the User Guide contains the supplement questionnaire.

The universe statements for each variable are defined in either the basic or supplement record layout, which are located in Attachments 6 and 7, respectively, of the User Guide.

ICPSR removed all FILLER and PADDING variables from the data. As a result, the column locations in any ICPSR-released data product (e.g., codebook and setup files) will have column locations that are not consistent with locations described in the User Guide.


Sample:    A multistage probability sample was selected to represent the universe of approximately 56,000 households per month. Approximately 73,000, 72,000, 71,000, and 71,000 housing units were selected for sample from the mixed sampling frame in January, May, July, and November 2005, respectively. Based on eligibility criteria, 11 percent of these housing units were sent directly to computer-assisted telephone interviewing (CATI). The remaining units were assigned to interviewers for computer-assisted personal interviewing (CAPI). Of all the housing units in the sample, about 61,000 were determined to be eligible for interview in January, and 60,000 in each of the other three months. Interviewers obtained interviews at about 56,000 of these units in January, and 55,000 in each of the other three months.

Weight:    The data contain one weight variable (PWSUPWGT) which is to be used for tallying records in the file. Users are strongly encouraged to refer to the User Guide for additional information on the weight was derived.

Mode of Data Collection:    computer-assisted personal interview (CAPI), computer-assisted telephone interview (CATI)
