The historical maps below show the state leading indexes from each month’s release back to June 2010. With each new release, the state leading indexes for prior months are revised and are available in the Revised Data spreadsheet (376 KB). These maps do not reflect subsequent data revisions.
July 17, 2015
Prior to the release of the June 2015 state coincident and state leading indexes, we discovered a processing error, which was part of the retrending step of the state coincident indexes. The error underestimated the underlying long-term growth trend used by both indexes for most states and affected all releases back through October 2010. A more detailed explanation with an analysis of the impact on each individual state can be downloaded. We issued revised releases, data, and maps for the May 2015 state coincident and state leading indexes. However, our series of historical maps will not be revised.
Prior to release of the May 2013 state leading indexes, we discovered a programming error that affected the input data for all releases back through June 2010. Instead of using state permits data on one- to four-family housing units, we were using state permits data on only the two- to four-family housing units segment. Corrections were made and all historical maps have been updated to reflect the correct data at their original date of publication.
