Download the SAS "file flattener" program for the 2009 AHS dataset (Download *.sas, 20 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 New Orleans survey topcode file (*.xls, 49 KB) 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.

Download the 2009 AHS New Orleans Symmetrical Tables (Download as *.zip, 70 KB updated 04/11/11)

The 2009 AHS New Orleans Symmetrical Tables show differences in housing and household characteristics of the same housing units interviewed in both 2004 and 2009, before and after the struck of Hurricane Katrina. Since the AHS is a longitudinal survey, these forward-looking tables present the 2009 characteristics of the 2004 New Orleans housing stock. For example, table 1 shows that 94,900 renter-occupied units in 2004 remained to be occupied by tenants in 2009 and only 17,200 renter-occupied units in 2004 became owner-occupied. Table 2 suggests that 63,100 households who were not below poverty line in 2004 were below poverty line in 2009. Table 9 indicates that the households who had a monthly housing cost between $400 and $499 incurred a median monthly housing cost of $732 in 2009.

Changes to the 2009 National American Housing Survey – New Orleans Metropolitan Area

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

Impact of Hurricane Katrina. Questions were added to assess the impact of Hurricane Katrina on housing and households in the New Orleans metropolitan area, including questions on the types of repair and remodeling work completed on Katrina-damaged units. A complete list of the new questions can be found here [HUD will insert document link].

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.)

Sample Adjustment for New Orleans. In order to comply with Census disclosure and confidentiality policies, the cases found in the New Orleans central city were dropped from the public use data file (PUF). For this reason, all the cases found in central city for the 2009 New Orleans PUF are new to the sample. The weight released on the PUF, however, adjusts for the cases that were dropped, so that accurate estimates for the New Orleans metropolitan area can be generated from the PUF.

Zone Adjustment for New Orleans. The 2004 central city zones 001-005 were collapsed to zones 006 and 007 to ensure that each zone had the minimum requirement of 100,000 people to comply with Census disclosure and confidentiality policies.

Uninhabited Units in New Orleans. There are still a number of homes in the New Orleans metro area that remain uninhabited. These cases can be found on the PUF by looking at cases where STATUS equals 4 (4=Noninterview) and NOINT equals 17 (17= “Not classified above, specify”). Units that are uninhabited due to damage caused by Hurricane Katrina can be further identified by selecting for HKDAMG=1.
