NOTES: Firms with less than 5 employees include those reporting no employees on their payroll. A firm is an entity that is either a single location with no subsidiary or branches or the topmost parent of a group of subsidiaries or branches. HT industries are defined by the Bureau of Labor Statistics (BLS) by the basis of employment intensity of the technology-oriented occupations based on BLS’s 2011 Occupation Employment Survey. HT small business employment is a lower-bound estimate because employment data are not available for a few industries due to data suppression.
