Fertility Rate
Live births per 1,000 females
'''Age-Specific Fertility Rate''': Live births to women in a certain age group, per 1,000 women in that age group. e.g., Live births to teen mothers aged 15-17 per 1,000 girls aged 15-17 in the population.
General Fertility Rate
Live births per 1,000 females aged 15-44.
Total Fertility Rate
Sum of the age-specific birth rates of women in five-year age groups multiplied by five. TFR estimates the number of children a cohort of 1,000 women would bear if they all went through their childbearing years exposed to the same age-specific birth rates in effect for a particular time.
