NOTE: Notes on total sample: Estimating the total number of NIH award winners is not an exact science. Data are maintained by firm names, which not only change, but are often recorded in nonstandard ways—a firm can be recorded separately as “Inc” “Inc,” Inc.” “Incorporated” or the “Inc” excluded altogether. Typos are frequently found in addition. The method used here for addressing this problem is to take the raw data from SBA, eliminate all suffixes, commas, and periods, and then review each individual record by hand. This was a three-step process. Initial review eliminated most of the duplicate entries. A second review generated a list of 1,567 firms. Final review, which took a more aggressive approach by eliminating duplicate names for firms in the same state and region, generated a final list of 1,536 firms.
