The Census is slowly releasing data from the 2007 Economic Census and they are presenting the data in a new report called Industry Snapshots . These reports give a graphic picture of industries at the 2 and 3- digit NAICS levels and include graphs of total shipments/sales, shipments/sales per employee, and a map of shipments/sales per capita. A table of industry ratios is included. Read more about these reports in this FAQ.
From any of the Snapshot reports, you can link to the Industry Sampler, the old familiar data page for an industry.
