About the numbers
Business counts: U.S. Census Bureau, County Business Patterns 2023. They count establishments (single physical locations) with paid employees, so firms with several locations count more than once and businesses with no employees are not included. Occupation and pay figures: U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics, May 2024. BLS counts employees only, so self-employed owners are not included in occupation figures. These are public statistics, not the size of the Evascrape database: list cost figures on these pages are upper bounds, because not every location has a matching contact, and you pay only for rows that are delivered. Evascrape prices are from the pricing page: $9 per 1,000 delivered contact records, smallest top-up $10 (about 1,100 records), optional email verification $5 per 1,000, no subscription.
