We use our local ES-202 data. Then enhance the heck out of it, over a 2 year period. We usually know where most of the holes are. Address matching the correct locations takes a long time. Hence, we never use the LEHD because it still has too many HQ addresses and less disaggregated business locations.

Cambridge Systematics, Inc. (CS) is working on a NCHRP task to improve employment data for transportation planning. The purpose of the task is to understand and describe both the Quarterly Census of Employment and Wages (QCEW) [or ES-202] and the Longitudinal Employer Household Dynamics (LEHD) data in a manner that enhances their utility and accessibility to transportation planning agencies. More details about the project can be found here: http://144.171.11.40/cmsfeed/TRBNetProjectDisplay.asp?ProjectID=2823 So where do you come in? I am interested in talking to MPOs and DOTs who are very confident about the quality of their employment data and have enhanced their employment data (assuming that the QCEW data is their main source) through either primary data collection/verification or via other secondary sources such as Dun & Bradstreet or InfoUSA (to name a few) or a combination of the two. If you are willing to share your employment data, CS will compare your employment data to the QCEW data by NAICS industry categories and will document the findings. BLS is also interested in making the QCEW data useful to more groups so if you agree, the results of our analysis will be shared with BLS so that any lessons learnt from MPOs and DOTs can be used to improve the quality of the QCEW data. Hopefully we can have a positive feedback cycle that benefits all parties and gets us better data. Please get in touch with me offline (contact details below) so as to avoid cluttering this mailing list. If there is interest i will share the findings with this list (after getting all the appropriate permissions to share). Thanks in Advance.
