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

description: This dataset, prepared by the Inter-university Consortium
for Political and Social Research, comprises 2 percent of the cases in
the second release of CENSUS OF POPULATION AND HOUSING, 1990 [UNITED
STATES]: PUBLIC USE MICRODATA SAMPLE: 5-PERCENT SAMPLE (ICPSR 9952). As
2 percent of the 5-percent Public Use Microdata Sample (PUMS), it
constitutes a 1-in-1,000 sample, and contains all housing and
population variables in the original 5-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 housing unit, type of
household/family, type of group quarters, household language, 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 cost of electricity, water, heating fuel, and
flood/fire/hazard insurance. Person variables cover age, sex,
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 limitation, work

occupation, industry, class of worker, hours worked last week, weeks
worked in 1989, usual hours worked per week, temporary absence 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 salary income,
farm and nonfarm self-employment income, Social Security income, public

description: This dataset was extracted by ICPSR from the 5-percent PUMS 
 using a systematic selection procedure. It contains all housing records 
 in the 5-percent PUMS coded 37 or 87 on the subsample variable, 
 SUBSAMPL, plus all person records associated with these housing 
 records. The number 37 was obtained by randomly selecting a number 
 between 0 and 99 (i.e., one of the 100 possible codes for SUBSAMPL), 
 and the number 87 was obtained by adding 50 to 37. (See Chapter 4 of 
 the codebook for an explanation of how SUBSAMPL may be used to select 
 PUMS subsamples.) The 5-percent PUMS, derived from responses to the 
 Census long-form questionnaire, is a 5-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 1990 Census.

description: To approximate weighted frequencies given by the
original 5-percent PUMS, users should multiply the weight variables,
HOUSWGT and PWGT1, by 50.This dataset has the same hierarchical
structure as the 5-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. Each vacant
housing unit is represented by a solitary housing record, which is not
followed by any person records. Every person residing in group quarters
is represented by a single housing record followed by a person record.
In all, this dataset contains 361,185 records.Appendix G of the
codebook (PUMS maps) is available only in hardcopy form upon request
from ICPSR.Code 6, which denotes this 1-in-1,000 sample, has been
added to the variable SAMPLE.
