*U.S.** Census Bureau, June 2008*

The Census Bureau's latest projections show world population growing at a
slower pace during the first half of the 21st century than the latter half
of the 20th century. The world population doubled from 3 billion in 1959 to
6 billion in 1999, but is projected to increase by only 50 percent between
1999 and 2040.

 Global population growth, about 1.2 percent per year, is projected to
decline to 0.5 percent by 2050. However, this growth will be concentrated in
less-developed countries.

About 1.5 percent of the current global population is 80 or older, with more
than half living in developed countries. By 2050, about 5 percent of the
world's population is projected to be 80 or older, with about three in four
likely to be living in less-developed countries. For developed countries,
the percentage of the population 80 or older will grow to about 10 percent
in 2050.

World population estimates and projections include the impact of HIV and
AIDS. Of the 34 countries updated in this revision, nine are hard hit by
this pandemic (Benin, Côte d'Ivoire [Ivory Coast], Eritrea, Ethiopia,
Guinea, Nigeria, South Africa, Zimbabwe and the Central African Republic).
Data for other countries seriously affected by HIV and AIDS are also
available from the International Data Base.

    The International Data Base offers online users a choice of ways to
retrieve demographic data, including:

·         Country summary pages showing key population indicators

·         Tables of demographic indicators for countries and regions
