Birth Data Background

• Age-specific central birth rates

• Births during the year to mothers at the specified age divided by the midyear 

female population at that age.

• Births from National Center for Health Statistics

• Resident population from Census Bureau.

• Total fertility rate (TFR)

• Sum of the age-specific central birth rates during the year.

• Can be interpreted as the average number of children that would be born to a 

woman if she were to experience, at each age of her life, the birth rate 

observed in, or assumed for, a specified year, and if she were to survive the 

entire childbearing period.
