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.

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.

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.

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.

2002-01-10 The data file and the codebook have been replaced by the Census Bureau due to a weighting error.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.
