2017 ACS 1-year and 2013-2017 ACS 5-year Data Releases: Technical Documentation
3. User References and Website Resources
3.1. Detailed Tables for the ACS Estimates
The 1-year Appendices and 5-year Appendices Excel files found on the Summary File Documentation page each contain a tab for Appendix A and Appendix B.
The table list in Appendix A for each data release contains information on all Detailed Tables included in the ACS Summary File. This appendix also includes information on geography restrictions for each table. For data quality and geographic reasons, some tables are published with specific geography restrictions. For example, the table B05001-PR, Citizenship Status in Puerto Rico, is produced for Puerto Rico only, and the table B08501, Means Of Transportation To Work By Age For Workplace Geography, is only produced for the work place geographies.
New additions to Appendix A this year include Topics in columns F and Universe in column G . The Topics column includes the ACS data topics covered, such as Age and Sex, Commuting, and School Enrollment, while the Universe column describes the total number of units (i.e., individuals, households, or businesses) in the population of interest, such as Total population, Housing units, or Workers 16 years and over.
