Birth rates are calculated as the number of live births divided by total population in the given year and then multiplied by 1,000. (For information about this formula see: http://sciencing.com/calculate-crude-birth-rate-4567314.html.)

This data is drawn from the joint Federal/State program by analyzing birth certificates that were issued in a given year.
