Medical science's two major effects on the birth rate are contraception and reduced infant mortality. Contraception allows for greater control over family planning and reduces the number of unintended pregnancies. Reduced infant mortality means that fewer infants die during childbirth or in the first year of life, which in turn reduces the need for families to have more children to ensure survival.
