a. Women in the rural town of Sinnuris, Egypt,
learn about family planning and birth control.

b. Developing countries around the world have experienced declines
in their fertility rates (TFRs) as women there have increased their use
of contraceptives. Solid lines represent fertility rates; broken lines
represent percentages of contraceptive use by women 15–49.

Based on data from U.S. Census Bureau.

a. Teen mothers gather at the
Auckland Girls' Grammar School
Eden Campus in Auckland, Australia,
a teen parenting facility that allows
young mothers to remain enrolled in
school. A demographer looking at
this scene would see the possibility
of lower TFRs for the women in this
photograph because they are
continuing their education.

b. Demographers know that the total number of children a
woman has during her life (TFR) is affected by the amount of
education she has received. The bar graph shows TFRs for 35- to
44-year-old women in the United States by level of education. A similar
trend—in which more education leads to lower TFRs—also occurs
among women in developing countries.
