Data on non-employers is out from the 2007 Economic Censuses, conducted by the U.S. Census Bureau. I’ve briefly summarized a few findings for New York City as compared with the United States in the attached spreadsheet; one can download the spreadsheet if interested in particular industries. The data shows that (as expected based on other data) New Yorkers are more likely than other Americans to work for themselves while not employing anyone else. New York City accounted for 2.75% of U.S. private sector employment in 2007 according to Current Employment Survey data, but it accounted for 3.5% of non-employer establishments according to the Economic Censuses, some 765,857 that year.
The self-employed were not particularly well paid here, averaging just over $44,000 in receipts here, slightly less than the national average. For private sector wage and salary employees, in contrast, those working in Downstate New York typically earn about one-third more than the national average, and far more in Manhattan. Despite the discussion of “mom and pop” stores in New York, the city only accounts for 2.6% of all Retail Trade establishments without employees. By sector, non-employer establishments are particularly common in New York City in Wholesale Trade, Transportation, Information, Health Care and Social Assistance, Arts & Entertainment, and Accommodation & Food Services. However the Professional, Scientific and Technical Services sector account for most non-employers both in NYC and the U.S. as a whole. Although most of the city’s wage and salary jobs are located in Manhattan, moreover, the self-employed are as likely to be located in Brooklyn or Queens. More detailed background and discussion of these industries follows.
