American Housing Survey, 1995: National Core File

<p>The American Housing Survey (AHS) collects data on the Nation's housing, including apartments, single-family homes, mobile homes, vacant homes, family composition, income, housing and neighborhood quality, housing costs, equipment, fuels, size of housing unit, and recent movers. National data are collected every other year, from a fixed sample of about 50,000 homes, plus new construction each year. In some metropolitan areas there are additional samples every 4-6 years, to measure local conditions. The 1995 National File includes extra cases to allow separate analyses of 6 Metropolitan Areas: Chicago, Detroit, Los Angeles, New York, Northern NJ, and Philadelphia. The weights have been set to give good data for both National and local studies.</p>
