Since May 18, the “beta” or testing release of our Q2 2010 dataset has been available to Analyst users. This release represents a major update to EMSI data. We expect to finalize this release in the next couple weeks.
NAICS 2007 Conversion
In this release, EMSI has converted all industry data to the 2007 version of the North American Industry Classification System (NAICS). To do this we have reconstructed our source and final datasets using NAICS 2007, including historical data that was originally coded in NAICS 2002. The new version of NAICS has a few dozen changes, most of which are concentrated in the manufacturing and telecommunications sectors (see below for full list of changes). If you have saved industry groups that contain defunct 2002 codes, you will be notified when you attempt to run a report on those groups in EMSI Analyst.
Due to the complexity of the reconstruction, as well as the tendency of establishments to reclassify themselves in unexpected ways following the NAICS conversion, EMSI advises caution when interpreting employment changes in affected industries from 2006 to 2007. Some changes may be the result of classification issues that do not accurately reflect the underlying labor market.

NAICS 2007 Conversion Details
The following table shows NAICS 2002 codes that no longer exist in NAICS 2007. Jobs in these industries have been redistributed to various other NAICS 2007 classification codes.
The following table shows new codes added in NAICS 2007:
The following table shows industry categories whose codes are the same in NAICS 2002 and 2007, but which gained or lost jobs due to a change in the category’s definition (e.g., jobs in a defunct 2002 code are now classified under one of these codes).
