About this ranking

Estimated births minus deaths of residents from July 1 of the previous year through June 30 of the reported year. A negative value means more deaths than births.

Equals births_july_june minus deaths_july_june for the same place and year. Not a calendar-year figure.

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.
