title: American Housing Survey, 2001: National Microdata
title: Version 1

description: This data collection provides information on the
 characteristics of a national sample of housing units including
 apartments, single-family homes, mobile homes, and vacant housing
 units. Unlike previous years, the data are presented in eight separate
 parts: Part 1, Work Done Record (Replacement or Additions to the
 House), Part 2, Worker Record, Part 3, Mortgages (Owners Only), Part
 4, Housing Unit Record (Main Record), Recodes (One Record per Housing
 Unit), and Weights, Part 5, Manager and Owner Record (Renters Only),
 Part 6, Person Record, Part 7, Ratio Verification, and Part 8, Mover
 Group Record. Data include year the structure was built, type and
 number of living quarters, occupancy status, access, number of rooms,
 presence of commercial establishments on the property, and property
 value. Additional data focus on kitchen and plumbing facilities, types
 of heating fuel used, source of water, sewage disposal, heating and
 air-conditioning equipment, and major additions, alterations, or
 repairs to the property. Information provided on housing expenses
 includes monthly mortgage or rent payments, cost of services such as
 utilities, garbage collection, and property insurance, and amount of
 real estate taxes paid in the previous year. Also included is
 information on whether the household received government assistance to
 help pay heating or cooling costs or for other energy-related
 services. Similar data are provided for housing units previously
 occupied by respondents who had recently moved. Indicators of housing
 and neighborhood quality are also supplied. Housing quality variables
 include privacy of bedrooms, condition of kitchen facilities, basement
 or roof leakage, breakdowns of plumbing facilities and equipment, and
 overall opinion of the structure. For quality of neighborhood,
 variables include use of exterminator services, existence of
 boarded-up buildings, and overall quality of the neighborhood. In
 addition to housing characteristics, some demographic data are
 provided on household members such as age, sex, race, marital status,
 income, and relationship to householder. Additional data provided on
 the householder include years of school completed, Spanish origin,
length of residence, and length of occupancy.

this collection.
description: The 2001 national data are from a sample of housing units
 interviewed between August and November 2001. The same basic sample of
 housing units is interviewed every two years until a new sample is
 selected. The United States Census Bureau updated the sample by adding
 newly constructed housing units and units discovered through coverage
 improvement efforts every enumeration. For the 2001 American Housing
 Survey-National (AHS-N), approximately 55,700 sample housing units
 were selected for interview. About 2,100 of these units were found to
 be ineligible because the unit no longer existed or because the units
 did not meet the AHS-N definition of a housing unit. Of the 53,600
 eligible sample units, about 5,400 were classified (both occupied and
 vacant housing units), as "Type A" noninterviews because (a) no one
 was at home after repeated visits, (b) the respondent refused to be
 interviewed, or (c) the interviewer was unable to find the unit. This
 classification produced a 90 percent overall response rate. The AHS
 sample consists of the following types of units in the sampled primary
 sampling units: housing units selected from the 1980 Census, new
 construction in areas requiring building permits, housing units missed
 in the 1980 Census, and other housing units added since the 1980
 Census. For more information about Sample Design, please see Appendix
B in CURRENT HOUSING REPORTS, 2001, included with this collection.

description: computer-assisted personal interview (CAPI)(1) Beginning in 1997, the methods of collecting and
 processing American Housing Survey (AHS) data were redesigned. All
 interviews are conducted using computer-assisted personal interviewing
 (CAPI) software, allowing new responses to some questions. Rather than
 existing as a single file, this collection consists of eight parts
 each containing data pertaining to a specific subject matter. In
 addition, data for building and neighborhood questions ceased to be
 collected through interviewer observation. Rather, these questions
 have been reworded for the respondents. Due to these changes, users
 are asked to use caution when comparing data prior to 1997 with data
 from 1997 forward. For further information about the redesign, please
 refer to DOCUMENTATION OF CHANGES IN THE 1997 AMERICAN HOUSING SURVEY
 included with AMERICAN HOUSING SURVEY, 1997: NATIONAL MICRODATA (ICPSR
 2912). (2) Beginning in 2001, three datasets: Part 2, Housing Unit
 Record (Main Record), Part 9, Recodes (One Record per Housing Unit),
 and Part 10, Weights, have been combined into one dataset, Part 4,
 Housing Unit Record (Main Record), Recodes (One Record per Housing
 Unit), and Weights. (3) The interview dates in the data file are not
 consistent with the dates listed under Sample Size in Appendix B of
 CURRENT HOUSING REPORTS, 2001, included with this collection. (4)
