In the United States today, there is a trend toward women having their first child in their late 30s or early 40s. In contrast, a few decades ago, most women started having children in their early 20s
What effect would you expect this change to have on population growth in the United States? Would it have any effect if the number of children per woman remains the same? Explain.
Population growth would be expected to slow even if the number of offspring per woman remains the same because the effective generation time has increased. The growth curve would be extended over a slightly longer time scale.
