U.S. Census Bureau Releases Documentation Supporting the 2016 American Community Survey (ACS) 1-Year Estimates


We are please to announce the first release of documentation in support of the 2016 American Community Survey 1-year estimates scheduled for release on Thursday, Sept. 14, 2017. This documentation offers ACS data users the opportunity to prepare for next week's data release.

New and updated information related to this release is available now on the 2016 Data Release page.

Highlights include links to the following:


The ACS provides reliable statistics that are used to make informed decisions about the future. These statistics are required by all levels of government to manage or evaluate a wide range of programs, but are also useful for research, business, education, journalism, and advocacy. If you have questions about this survey, please call our Customer Services Center on 1 (800) 923-8282. 

To request a free data workshop, training, or presentation from the U.S. Census Bureau, please contact the Data Dissemination Office at census.askdata@census.gov or 1-844-ASK-DATA (1-844-275-3282).

  • I just downloaded the Excel version of the Sequence Number Table Number lookup table from here www.census.gov/.../summary-file-documentation.html, and it appears to be missing half of the records. (The last record in the file is row 16385 - partway through the B18135 table.)

    Could you please re-post a corrected file?
  • Thank you for bringing this to our attention. We are looking into it and will let you know when a resolution is reached.
  • Hello, I made the following suggestion for the 2011-2015 ACS release:

    Would it be possible to make the full ACS geography files available in advance of the release? [...] Normally these geo files arrive along with the summary file release on embargo day, but I can't think of any reason why the geos need to be embargoed. It would be really helpful to have this data ahead of time.

    Justin Keller responded:

    Hello and thank you for the feedback. While it is obviously too late to implement for DY2015, I have passed along this information to our ACS data products area and they have it under consideration for the DY2016. It sounds like they will be able to accommodate this request.

    Any news on this? Can the ACS data products group release the geography files in advance of the full data release next week?

  • In reply to Glenn Rice:

    To add to Glenn's request, it would also be incredibly useful to have the Summary File Templates (files that look like Seq1.xls) and Table Shells (ACS2015_Table_Shells.xlsx) in advance. I can't express how helpful it would be to have these already when the actual data is released.
  • In reply to Beth Jarosz:

    Beth, I made a corrected CSV version from the SAS file -- but I can't post it here (too big). If the bureau is slow to fix, I can email it to you
  • In reply to Bernie:

    Bernie, the table shells file is already available at the link above
  • In reply to Glenn Rice:

    Excellent suggestion - I'll do the same (either from the text file or SAS file).
  • Beth- thanks again for bringing this to our attention. The full Excel version of the Sequence Number Table Number lookup table has been reposted to www.census.gov/.../summary-file-documentation.html
