|Title:||Census of Population and Housing, 1990 [United States]: Public Use Microdata Sample: Puerto Rico: 5% Sample|
|Abstract:||The Public Use Microdata Sample (PUMS) 5-Percent Sample contains household and person records for a sample of housing units that received the "long form" of the 1990 Census questionnaire. Data items cover the full range of population and housing information collected in the 1990 Census, including 500 occupation categories, age by single years up to 90, and wages in dollars up to $140,000. Each person identified in the sample has an associated household record, containing information on household characteristics such as type of household and family income. Unlike previous years, the 1990 PUMS 1-Percent and 5-Percent Samples have not been released in separate geographic series (known as "A," "B," etc. records). Instead, each sample has its own set of geographies, known as "Public Use Microdata Areas" (PUMAs), established by the Census Bureau with assistance from each State Data Center. The PUMAs in the 5-Percent Sample are based on counties and places within states. Each PUMA is a county or place, or groups thereof, except when the county or place contains more than 200,000 inhabitants. In that case, the county or place is divided into several PUMAs. PUMAs in this 5-Percent Sample do not cross state lines.|
