About this ranking

Jobs added at opening and expanding establishments during the year, as a percentage of average employment in the two years. United States: Census Bureau Business Dynamics Statistics.

A gross flow: jobs lost elsewhere are not subtracted, so the net change is this rate minus job_destruction_rate. Not the same as payroll job growth from the monthly employment surveys. 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.
