We use the National Establishment Time Series (NETS) to revisit the debate about the role of small businesses in job creation (Birch, 1987; Davis, Haltiwanger, & Schuh, 1996a).

The results indicate that small firms and small establishments create more jobs, on net, although the difference is much smaller than Birch's methods suggest. Moreover, in the recent period we study, a negative relationship between establishment size and net job creation holds for both the manufacturing and services sectors.
