We are pleased to announce the first release of documentation in support of the 2017 American Community Survey 1-year estimates scheduled for release on Thursday, September 13, 2018. 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 2017 Data Release page.

Highlights include links to the following:

• The Table & Geography Changes page explains new, modified, and removed tables, as well as information on changes to geography.

• The Code Lists, Definitions, and Accuracy page includes code lists, subject definitions, group quarters definitions and instructions for applying statistical testing.

• The Summary File Documentation page includes the technical document, table shells, and sequence/table number lookup files.  New this year: the 1-year appendices include the topics and universe for each table number.
  

• Table Shells display the layout of the tables without the estimates or margins of error filled in.

• The Geography Boundaries by Year page shows which vintage of geography the 2017 ACS 1-year estimates are based on.

• The Areas Published page lists the total number of geographic areas that receive 2076 ACS 1-year estimates. An excel file also details the specific geographies that have published data.
