Uganda has one of the highest fertility rates in the world at seven children per woman, and has the youngest population on the planet with a median age of less than fifteen. Large families trap people in poverty with not enough money for food, schooling and health care for their children. High fertility rates are dangerous for women, and make it hard for them to escape traditional childbearing roles. A 3% annual population growth rate is unsustainable for the environment, and leaves younger generations without enough water or land for cultivation.
