Data in the 9/21/2010 Survey of Business Owners (SBO) release will be revised on 12/7/2010. This is a planned data revision coincident with the release of new data for women-, men-, and equally-owned firms. The continuing review of ownership characteristics for each new publication from the 2007 SBO will result in revisions to data previously released until final estimates are released in June 2011. Contact the SBO staff at 301-763-3316 for more information.
