Description: The sample was taken from households in the AHS, 1977 SMSA files. The collection consists of 20 data files, one for each SMSA represented. There are 94,783 total records in the collection. The number of records ranges from 1,255 for Saginaw, Michigan to 13,340 for Los Angeles, California. Each file contains approximately 65 variables and has a logical record length of 372 characters.
Notes: The Annual Housing Surveys are comprised of two major data collections for each year: the first, a national sample of housing units, and the second, a sample of housing units in each of roughly 15-20 SMSAs per year. The national data is released by the Census Bureau in two forms: the National Core file and the National Core and Supplement. Also, in addition to the primary SMSA file, specific transportation data by SMSAs is available in the Travel-to-Work files. Complete descriptions of these four files follows. For all Annual Housing Surveys, data are collected on whether the housing units have kitchens, heating units, and electrical systems and, if so, how well these work. Information on the costs incurred for mortgage payments, real estate taxes, property insurance, utilities, and garbage collection allow comparisons of housing costs from one year to another or between geographic areas. Data collected on income can be used in conjunction with annual housing expenditures to estimate the average percentage of families' and primary individual's incomes which is spent on housing. Households which have moved in the 12 months prior to enumeration are asked to provide comparative information on the current and previous residences of household heads.

Information is collected on whether employment, family, or other factors such as changes in neighborhood or financial conditions influenced the decision to move. The National Core and the National Core and Supplement files contain a sample of households chosen each year for the AHS. Each household completes a set of core questions about housing expenditures, taxes, insurance, etc., and an additional set of supplement questions which vary from year to year. The National Core files are released from the Census Bureau first, and they only contain the core questions. The National Core and Supplement (here referred to as simply the ''National'' files) contains both core and supplement questions. The SMSA files contain annual housing characteristics for a sample of housing units in each of roughly 15-20 SMSAs per year. This sample of SMSAs changes yearly, thus, a total of 60 SMSAs is surveyed every 3 or 4 years. The Travel-to-Work supplement was designed to provide current information for the selected metropolitan areas concerning such subjects as place of work, means of transportation to work, carpooling and carpool occupancy, travel time to work, distance to work, time of departure for work, and other transportation-related subjects.

This collection contains transportation data from the supplement and selected demographic and household characteristics which are also available from the AHS Public Use Files. Questions on travel to work were asked of all household members 14 years of age and over who had a job during the week prior to the interview.
