|Abstract:||This data collection provides detailed tabulations of 100-percent data items from the 1990 Census of Population and Housing. These tabulations are presented for states and their subareas in hierarchical sequence down to the census tract or block numbering area (BNA) level. Population items include age, race, sex, marital status, Hispanic origin, household type, and household relationship. Population items for Puerto Rico include persons, families, households, sex, age, marital status, household size and household type. Housing items include occupancy/vacancy status, tenure, units in structure, contract rent, meals included in rent, value, and number of rooms in housing unit. Crosstabulations include variables such as single year of age by sex, tenure by age of householder, age by group quarters, aggregate value by units in structure, and tenure by number of nonrelatives. The dataset contains both ''A'' and ''B'' records. ''A'' records are provided for each summary level in a geographic area, and are repeated for each geographic component. ''B'' records repeat the same data for each summary level/geographic component combination, but are tabulated for each of ten categories of race and Hispanic origin.|
