Summary File Documentation
The American Community Survey (ACS) Summary File is a set of comma-delimited text files that contain all of the Detailed Tables for the ACS 1-year, 3-year, and 5-year data releases. Summary File estimates, margins of error, and geography files for each release are available via the Summary File Data page.
The Detailed Tables are stored in a series of files with only the data from the tables and without such information as the table title, description of the rows, or geographic identifiers. That information is located in other files that the user must merge with the data files to reproduce full tables.
Starting with the 2009-2013 ACS 5-year data release, block groups, the lowest level of geography published by the ACS, are available in American FactFinder. For earlier years, block groups are available only in the ACS 5-year Summary File.
Appendices include the sequence number and restrictions for all tables, as well as summary levels available for each release
Contains table ID, line number, unique ID (table ID + Line Number), stub, and data release
Contains information on the relationship between the sequences and the tables
Contains SAS programs for each sequence per state, which can be used to convert each estimate and margin of error into SAS Datasets with table stubs
Detailed example SAS program containing SAS macros which access the geography, estimate and margin of error data. It creates one table for all geographies from the ACS Summary File. Segments of the SAS codes can be used to convert geography files into SAS datasets
