AHS 2011 National and Metropolitan Public Use File (PUF)

Microdata are files containing individual responses to survey questions. They are used to create custom tabulations, allowing users to delve further into the rich detail collected in the American Housing Survey. In the AHS microdata, the basic unit is an individual housing unit. Each record shows most of the information associated with a specific housing unit or individual, except for data items that could be used to personally identify that housing unit or individual.

SAS "Flat File"

The flat file is a SAS dataset where the individual Public Use File datasets have been combined into a single SAS dataset, with one record per housing unit.

Topcodes and bottom codes are in the AHS PUF. 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.
