The data from the 2009 American Housing Survey and the documentation about the survey are available on this page. We have the instrument items booklets, which are human-readable documents listing all of the items in the survey instruments, and we have a runnable copy of the 2009 computerized interviewing instrument itself. If you download and install this on your Windows-capable computer, you can step through an AHS interview just as a Census Field Representative would conduct it.

Download the SAS "file flattener" program for the 2009 AHS dataset (Download *.sas, 19 KB)
The file flattener program is a SAS routine that extracts the eight individual SAS files from the transport dataset and produces a single SAS file, with one record per housing unit. Observations on persons, commuting, recent mover groups, and alterations & repair projects are transformed into numbered groups of variables in the housing unit record. While this file structure requires about twice as much disk space as the individual files, some users find it easier to use.

2009 national survey topcode file (*.xls, 48 KB, Updated on 12/16/2011)
Topcodes and bottom codes are used in the AHS public use file in order to maintain confidentiality. Unusually high (and, in a few cases, low) values in the AHS dataset are replaced with maximum (or minimum) values, called top (or bottom) codes. This MS-Excel spreadsheet documents these values for the affected variables.

2009 Instrument Items Booklet (2009 Questionnaire) (*.pdf, 790 KB): The instrument items booklet is a PDF document that lists all the questions and responses in the AHS survey instrument. It was prepared for the Office of Management and Budget as part of the survey clearance process. This is the closest equivalent to a paper version of the AHS questionnaire.

2009 Table Specifications (*zip, 150 KB): This zip archive contains the SAS code files used by the U.S. Census Bureau in producing its tabulations of the 2009 national American Housing Survey (AHS), which can be found at http://www.census.gov/hhes/www/housing/ahs/ahs09/ahs09.html. These files are provided so that experienced data users can match the Census specifications when producing their own tabulations using the AHS public use file (PUF).

AHS 2009 Value Label Package (*zip, 32 KB)
The value labels package is a set of files that attach SAS formats to many variables in the 2009 AHS public use file. This will allow you to format your SAS output to display meaningful labels for AHS values. For example, a tabulation of TENURE will display as "Owned," "Rented for cash," "No-cash rent," etc., instead of "1," "2," "3," etc. Users of other analytic software may find the files in this package handy for copying and pasting value labels, saving the effort of typing.

Replicate Weights For AHS 2009 National Last updated on 11/14/2012 (*pdf, 190 KB)
The American Housing Survey - National Sample (AHS-N) is a probability sample of housing units. Several methods can be used to estimate sampling variance for complex sample designs like the design used in the AHS-N. One computationally efficient method for calculating sampling variance is the method of replication, where replicate weights are used to estimate the variance. For the first time, the Census Bureau is releasing a replicate weight file that can be used with the AHS-N public use data file so that data users can generate variance estimates themselves with ease.

Metropolitan Supplement Comparer Files (*zip, 787 KB): The 2009 national American Housing Survey (AHS) included special supplementary samples of housing units in five metropolitan areas: Chicago, Detroit, Philadelphia, New York, and Northern New Jersey. The data collected in these supplementary samples are included in the national AHS public use file (PUF). As part of the quality control process, Econometrica, Inc., under contract with the Department of Housing and Urban Development (HUD), produced a set of spreadsheets to compare standard tabulations of the 2009 data with the 2003 AHS (the previous survey in which supplementary samples were included). This zip archive contains the comparison files, to help data analysts understand the major changes between these data files.

 

Changes to the 2009 National American Housing Survey

 

ITEMS ADDED

Households with Disabled Persons. Questions were added to determine the disability status of household members.


OTHER

Public Use File. The Ratio Verification (RATIOV) file returns for 2009. The file contains data on the verification of income to cost when the ratio of income to cost is outside of certain tolerances. (Note: This file was present from the 1998 AHS metro sample to the 2005 national sample. This file is not present in 1997 or in 2007.)

Supplemental Sample Size for Each of the Five AHS-National-Based Metropolitan Areas. A supplemental sample of housing units was selected in five large metropolitan areas (Chicago, Detroit, New York, Northern New Jersey, and Philadelphia). This sample was combined with the existing sample in these areas in order to produce metropolitan level estimates. Most of this sample was interviewed for the first time in 2009. The sample size for each area is shown below.
