In 2011, the world’s population will surpass 7 billion. While the rate of population growth has slowed in most parts of the world, we still increase by nearly 80 million people every year—the equivalent of adding another U.S. to the world every four years. The number of people on the planet has doubled since 1960, and if current growth rates continue, the world’s population would hit 11 billion by 2050. Common estimates of a 9 billion plateau for world population rest of questionable assumptions about falling fertility rates and the availability of contraception. Currently, 215 million women around the world want to avoid pregnancy but need contraception.
Most countries in the developing world have high fertility rates and are getting younger; some developed countries have low fertility rates and are aging. Research has shown that demographics can have a significant impact on countries’ stability, governance, economic development and the well-being of its people. PAI believes that the future of population growth will be shaped by actions we take today, including providing access to family planning.
