“Demand for family planning satisfied with modern methods” has emerged as a key indicator of contraceptive availability and use. The indicator measures the proportion of women who want to delay or limit childbearing and who are using modern methods of contraception. Family planning experts have urged countries to strive for meeting at least 75 percent of demand with modern methods. Over the past two decades, a significant number of less developed countries have seen increases in the share of demand satisfied with modern methods, but many countries remain far below the proposed 75 percent benchmark. They will need to accelerate progress over the coming decade so that increased contraceptive use can translate into improved maternal and child health, slower population growth, increased economic well-being, and environmental sustainability.
