Note(s):

Award data drawn from SBIR.gov for 1983–2022. Mean values are given for the number of awards to each unique firm in the category for Women-Owned Small Businesses (WOSB); Historically Under-utilized Business Zones (HUBZones); and socially disadvantaged businesses (SDBs). T-tests are used to test the equality of means, and increasing p-values indicate statistical equivalence
