Document Summary
Also refers to branch of demography that studies births. Natality: is a term also used for fertility. With root meaning to be born, natality implies emphasis on the newborn. Giving birth is a sociologically more interesting that being born because moms (and dads) engage in more decision making regarding birth than do babies. Virtually all births in the us are recorded. Crude birth rate (births/population)*1000= 12. 4 births / 1000 in us in 2013. General fertility rate (gfr) = (number of live births) / (women 15-44 years old) *1000. Tell the likelihood a woman of childbearing age will have a baby. Age-speci c fertility rate gives chances woman of a particular age will have a baby. Total fertility rate gives mean number of babies woman would have in her lifetime if age-speci c fertility rates do not change and she lives to 45. Replacement fertility: fertility rate that over long term will yield no population growth or shrinkage (ignoring migration)
