About this ranking

New employer firms: firms of age zero in March of the year, meaning that every establishment of the firm had its first employees during the previous twelve months. United States: Census Bureau Business Dynamics Statistics, which calls these firms startups.

A firm counts only when it has employees, so a business without staff is not a birth, and a new branch, merger or change of ownership of an existing firm is not a birth either. Not the same as business_applications (requests for an employer number) or enterprise_births (European business demography). The year is the twelve months to March: 2023 compares March 2022 with March 2023.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
