Shrinking shares of job-creating, high-growth firms across the country, the topic of SSTI’s Useful Stats column in last week’s Digest, is not being experienced within all sectors of the economy, according to analysis of the Business Dynamics Statistics of High Growth Firms (BDS-HG) experimental dataset from the Census Bureau. From 1978-2021, the number of high-growth firms, measured by change in employment, has increased in five sectors, stayed the same in one, and decreased in the remaining 13 classifications of U.S. business and industrial activity. Slower-growth firms expanded their dominance of the economy, as all sectors experienced a decrease in the number of high-growth firms as a percentage of their total respective firms.
