Changes to the Data

Superseding tables

Tables released earliest, like the Industry Series, may be superseded by data in later releases, like the Geographic Area Series (GAS).

Some tables from the Industry Series will still be available in American FactFinder, but the GAS and Subject/Summary Series tables will have the latest data.

Revisions (Corrections)

After analysis and processing, data values are occasionally revised and updated.

  • If a number changes and differs greater than a certain percentage of the initial value, then a new value will be released with an '(r)' after it to signify the revision.
  • If a number changes and differs less than a certain percentage of the initial value, then there is no notice of revision.
  • The threshold varies on the sector or program that produced the data.

Note: Revisions are only applied when data in a particular table are reissued due to the identification of an error. Preliminary data that are released in one table and then released later in another table do not get an '(r)' flag, even if they have changed.
