Scope of Study

Summary:This data collection supplies standard monthly labor force data as well as supplemental data on work experience, income, noncash benefits, and migration. Comprehensive information is given on the employment status, occupation, and industry of persons 15 years old and older. Additional data are available concerning weeks worked and hours per week worked, reason not working full-time, total income and income components, and residence on March 1, 2000. This file also contains data covering noncash income sources such as food stamps, school lunch programs, employer-provided group health insurance plans, employer-provided pension plans, personal health insurance, Medicaid, Medicare, CHAMPUS or military health care, and energy assistance. Information on demographic characteristics, such as age, sex, race, household relationships, and Hispanic origin, is available for each person in the household enumerated.
 
Subject Term(s):census data, demographic characteristics, employment, Hispanic origins, households, income, job history, labor force, Medicaid, Medicare, occupational mobility, population characteristics, population estimates, unemployment, working hours
 
Geographic Coverage:United States
 
Date(s) of Collection:March 2001
 
Universe:Civilian noninstitutional population of the United States living in housing units and members of the Armed Forces living in civilian housing units on a military base or in households not on a military base.
 
Data Type:survey data
 
Data Collection Notes:(1) In this hierarchical dataset, there are three record types. The first record type is Household, with 142 variables for 64,362 records. The Family record type has 76 variables for 56,480 records, and Person records have 471 variables for 128,821 records. There are a total of 249,663 records in the file. (2) The codebook is provided by the principal investigator as a Portable Document Format (PDF) file. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided on the ICPSR Web site.
 

Methodology

Sample:A national probability sample was used in selecting housing units. About 60,000 housing units were contacted, with an additional 3,500 Hispanic households added to the March survey sample. The sample was located in 792 sample areas comprising 2,007 counties and independent cities with coverage in every state and the District of Columbia.
 
Data Source:personal interviews
 

Access and Availability

Note:A list of the data formats available for this study can be found in the summary of holdings. Detailed file-level information (such as record length, case count, and variable count) is listed in the file manifest.

Version History:The last update of this study occurred on 2002-01-10.
 
  2002-01-10 - The data file and the codebook have been replaced by the Census Bureau due to a weighting error. The error resulted in the assignment of incorrect weights to records in the Annual Demographic file. National estimates of median and mean income, poverty rates, and health insurance coverage were only minimally affected (see Table in User Note 1 in the codebook). Weights for adults (age 16 years and older) were only minimally affected. The impact was primarily on the weights for children (under the age of 16) and varied by state. Thus, sub-national estimates of children's data are most likely to show a change when using corrected weights. However, since the weighting problem affected all records on a proportional basis, ratio estimates and percent distributions should show only minor changes, even those for children.
