Many human generations ago, most women worldwide began childbearing in their mid-teens. Today, a large proportion of women worldwide delay childbearing until their 20 s. Among college-educated women in developed nations, the trend in delaying reproduction has been taken even further; childbearing often is delayed until past age 30 due to education and career pressures. Suppose that most women worldwide were to delay childbearing until age 30 , and that women were to continue to make this choice for many human generations. Make a prediction about how human life span and fertility might evolve in response.
Having Children? The Pew Research Center recently reported that $18 \%$ of women $40-44$ years of age have never given birth. Suppose a random sample of 250 adult women $40-44$ years of age results in 52 indicating they have never given birth. Explain why this is not necessarily evidence that the proportion of women $40-44$ years of age who have not given birth has increased since the time of the Pew study.
