Chapter 3. User Tools
3.1. Summary File Excel Retrieval Tool
For 2005-2009 ACS 5-year data, there are 295 Detailed Tables and all block group data not available on AFF. If only a few tables are needed, a useful tool is the Summary File Excel Retrieval Tool. If users have Excel 2007 or later, the tool is able to get tables from an entire sequence and from a summary level and component. Information on how to use Summary File Excel Retrieval Tool is located on the ACS Summary File page, at www.census.gov/acs/www/data_documentation/summary_file.

Hardware and Software requirements for the application include:

  • Microsoft Windows XP Professional Service Pack 3 or newer (a Mac version is being developed)
  • Winzip version 14.5 or compatible
  • Office 2007 or newer
  • DSL connection at 1.0 Mbps or greater is recommended

3.2. Summary File SAS Tool
For users with SAS software, please visit the User Tools folder www2.census.gov/acs2009_5yr/summaryfile/UserTools/ to download SAS programs. These programs allow users to load the Summary File data into SAS Datasets. The SAS programs serve as a reference for the users, and include variable labels, however modifications may be necessary before users can get the data. After the needed Summary File data have been downloaded, users should specify the locations in the library references and the infile statements.

  1. SF20095YR_SAS.zip - Contains SAS programs, which can be used to convert each estimate and margin of error into SAS Datasets. The SAS datasets include table stubs. There is one individual SAS program for each sequence per state.
  2. SF_All_Macro.sas - This is a detailed example SAS program containing SAS macros which access the ACS Summary File geography, estimate and margin of error data. It creates one table for all geographies from the ACS Summary File.

3.3. Summary File Excel Import Tool
This tool requires that users first download the Summary File data and Excel Templates SummaryFileXLS.zip from www2.census.gov/acs2009_5yr/summaryfile/UserTools/.
