WORLD POPULATION Bureau: Factors help slow growth
Family planning and AIDS education could change the trend.
WASHINGTON (AP) -- Fewer births and more deaths from complications from AIDS are helping slow world population growth, the Census Bureau says.
In a report Monday, the bureau forecast a world population of about 9.1 billion people by 2050, a nearly 50-percent increase from the 6.2 billion in 2002. However, the growth rate is slowing significantly.
The global population grew 1.2 percent from 2001 to 2002, or about 74 million people, but growth will slow to 0.42 percent by 2050. That's far below the peak growth of 2.2 percent between 1963 and 1964.
The projections are generally in line with separate forecasts from the United Nations and private researchers. The 2050 world projection is slightly lower than the 9.3 billion forecast in a previous bureau report on the topic in 1998.
Factors could change
Officials warned that such forecasts are based on two factors that could change: fertility rates in developing countries and the AIDS epidemic.
Generally, in the United States and Europe, women are having fewer children, while fertility rates remain high in India, parts of Africa and some other developing countries, said Carl Haub, a demographer with the Population Reference Bureau, a private research group.
The wild card is how prevalent contraceptive use and family planning becomes in these countries, Haub said. As an example, he cited India, where the population is expected to rise more than 50 percent to 1.6 billion in 2050, surpassing China as the most populous country.
According to the bureau, there are at least 100 million women in the world's developing countries who would like to space or limit their pregnancies but are not using contraception.
Family planning education in India and Africa is difficult because of the large numbers of rural villages that cannot easily be reached, Haub said.
In 2002, the world's women gave birth to an average of 2.6 children over their lifetime. The bureau projections assume that the fertility rate will drop below two children per woman by 2050.
Meanwhile, AIDS has led to the deaths of more than 20 million people since the epidemic began two decades ago. Twice that many people now live with HIV, the virus that leads to AIDS, and barring major medical breakthroughs most of these people are expected to die within the next 10 years, the bureau said.
AIDS continues to have its greatest impact in developing countries of Asia, Latin America and especially sub-Saharan Africa. Botswana and South Africa are among countries that may see population decline because of AIDS-related deaths.
