Why do company counts differ?
The U.S. Economic Census counts establishments with paid employees that operated during the census year, including businesses that may have since closed. Its industry classifications draw on business-reported information and government records. SICCODE.com's counts reflect verified business records currently available for purchase, with classifications based on documented business activities. Differences in reporting periods, database coverage, classification methods and verification criteria mean the totals may differ.
