title: Census of Population and Housing, 1990 [United States]: Public Use Microdata Sample: 1/10,000 Sample
title: Version 1

description: This dataset, prepared by the Inter-university Consortium 
 for Political and Social Research, comprises 1 percent of the cases in 
 the second release of CENSUS OF POPULATION AND HOUSING, 1990 [UNITED 
 STATES]: PUBLIC USE MICRODATA SAMPLE: 1-PERCENT SAMPLE (ICPSR 9951). As 
 1 percent of the 1-Percent Public Use Microdata Sample (PUMS), the file 
 constitutes a 1-in-10,000 sample, and contains all housing and 
 population variables in the original 1-Percent PUMS. Housing variables 
 include area type, state and area of residence, farm/nonfarm status, 
 type of structure, year structure was built, vacancy and boarded-up 
 status, number of rooms and bedrooms, presence or absence of a 
 telephone, presence or absence of complete kitchen and plumbing 
 facilities, type of sewage, water source and heating fuel used, 
 property value, tenure, year moved into house/apartment, type of 
 household/family, type of group quarters, language spoken in household, 
 number of persons, related children, own/adopted children, and 
 stepchildren in the household, number of persons and workers in the 
 family, status of mortgage, second mortgage, and home equity loan, 
 number of vehicles available, household income, sales of agricultural 
 products, payments for rent, mortgage, and property tax, condominium 
 fees, mobile home costs, and costs for electricity, water, heating 
 fuel, and flood/fire/hazard insurance. Person variables cover age, sex, 
 and relationship to householder, educational attainment, school 
 enrollment, race, Hispanic origin, ancestry, language spoken at home, 
 citizenship, place of birth, year of immigration, place of residence in 
 1985, marital status, number of children ever born, presence and age of 
 own children, military service, mobility and personal care limitations, 
 work limitation status, employment status, employment status of 
 parents, occupation, industry, and class of worker, hours worked last 
 week, weeks worked in 1989, usual hours worked per week, temporary 
 absences from work, place of work, time of departure for work, travel 
 time to work, means of transportation to work, number of occupants in 
 vehicle during ride to work, total earnings, total income, wages, and

description: The 1-in-10,000 sample, extracted from the 1-Percent PUMS 
 by ICPSR using a systematic selection procedure, contains all housing 
 records in the 1-Percent PUMS coded 16 for the subsample variable, 
 SUBSAMPL, plus all person records associated with these housing 
 records. The number 16 was randomly chosen among the 100 possible codes 
 for SUBSAMPL, 00 to 99. (See Chapter 4 of the codebook for an 
 explanation of how SUBSAMPL may be used to select PUMS subsamples.) The 
 1-Percent PUMS, derived from responses to the 1990 Census long-form 
 questionnaire, is a 1-percent stratified sample of persons and housing 
 units enumerated in the 1990 Census (housing units and their occupants, 
 vacant housing units, and persons in group quarters). The long-form 
 questionnaire was administered to approximately 15.9 percent of 
households counted by the Census.

description: (1) To approximate weighted frequencies given by the 
 original 1-Percent PUMS, users should multiply the weight variables, 
 HOUSWGT and PWGT1, by 100. (2) This dataset has the same hierarchical 
 structure as the original 1-Percent PUMS. There is a separate record 
 type for each of the two levels in the hierarchy: the housing level is 
 represented by a housing record comprising 112 housing variables, the 
 person level by a person record comprising 123 person variables. (These 
 variable counts do not include the housing serial number, SERIALNO, and 
 the variable denoting the record type, RECTYPE. These two variables 
 appear on both the housing and person records.) Each occupied housing 
 unit is represented by a single housing record followed by one or more 
 person records, one for each person in the household. Housing records 
 representing vacant housing units are not followed by any person 
 records. Each person residing in group quarters is represented by a 
 housing record followed by a person record. In all, this dataset 
 contains 36,179 records: 11,074 housing records and 25,105 person 
 records. Every housing and person record has a logical record length of 
 231. (3) Appendix G of the codebook (PUMS maps) is available only in 
 hard copy form upon request from ICPSR. (4) Code 5, which denotes this 
1/10,000 sample, has been added to the variable SAMPLE.
