About this ranking

Establishments that opened during the year (employees in March of the year and none a year earlier), as a percentage of the average number of establishments in the two years. United States: Census Bureau Business Dynamics Statistics.

An establishment is a single physical location, so a new branch of an existing firm counts as an entry: this is not the rate of new firms. Not comparable with enterprise_birth_rate, which counts new enterprises in Europe. 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.
