"PAI Releases First High-Resolution World Map of Future Population Growth and Decline
New Mapping Technology Projects Human Population Changes for Year 2025

Washington,
DC… Pockets of rural Africa, Latin America and Asia are likely to
lose population in the next two decades despite generally increasing
density in these regions, a new map of projected future population
increase and decline suggests.
Population Action International (PAI)
will release on Earth Day a first-of-its-kind, high-resolution map of
projected population change for the year 2025, showing a world with
large areas of population loss but overwhelmingly still increasingly
filled with people. The map, a collaboration with researchers at the
Center for Climate Systems Research at Columbia University, is being
released in conjunction with a 2006 update of PAI’s Web data feature,
People in the Balance, on the relationships of human population with
fresh water, cropland and other critical natural resources.
“The
technology for mapping population density keeps improving, and we’re
pushing it a bit further with this map,” notes Robert Engelman,
PAI’s Vice President for Research. “We can’t really ‘map the
future.’ But we can use detailed maps of current population density
and the latest country population projections to calculate the most
likely locations for population gains and losses worldwide.”
Mapped
population projections will be of particular interest to
conservationists, climate specialists and others who need to know where
people will live, and in what numbers, in the decades ahead. The
technology may also provide “best guesses” of where and how many
people in the future are likely to be vulnerable to natural disasters.
PAI’s
partners at Columbia University were Dr. Stuart Gaffin and Lee
Hachadoorian, now of City University of New York Graduate Center and
Hunter College. To produce the map, the researchers extrapolated out to
2025 changes in population from 1990 to 1995 that occurred in grid
cells that are about three miles wide at the equator and decrease in
size toward the poles. The researchers selected from two alternative
mathematical approaches to arrive at the best and most likely fit with
the United Nations’ “medium variant” projection for each
country’s population.
The Map of the Future indicates that the
greatest increases in population density through 2025 are likely to
occur in areas of developing countries that are already quite densely
populated. The map also projects areas — much of southern and eastern
Europe and Japan — of fairly dramatic depopulation. More
surprisingly, the map indicates small areas of projected population
decline in many regions in which they might be least expected:
sub-Saharan Africa, Central and South America, the Philippines, Nepal,
Turkey, Cambodia, Burma and Indonesia. Currently, all of these regions
have overall populations growing at a modest-to-rapid clip.
“We
believe these are mostly rural areas that are experiencing rapid
out-migration to urban centers,” explains Engelman. “Land
degradation in these areas may be making subsistence farming
uneconomical even for stable populations.”
Despite concerns about
population decline in the industrialized world, much more of its land
area is projected to experience population growth than decline in the
next 20 years. There’s little projected decline in North America and
almost none in Australia and New Zealand. Modest growth is projected
for Northwestern Europe despite projected decline elsewhere on that
continent. The vast majority of the world’s land will have many
millions more people in 2025 than today.
“This map is a
projection, and Population Action International would be happy if the
reality of 2025 is far rosier than what we see here,” comments Amy
Coen, PAI’s President and CEO. “The issue of population is more
complex than it was a few decades ago. Where people move and where they
settle affect every aspect of their lives, as well as the health of the
countries in which they live. This map gives us a glimpse into the
future, and the opportunity to create a healthier one while there is
still time.”
The map is being made available on both [url="http://"http://www.populationaction.org/mappingthefuture"]PAI's website[/url] and at [url="http://"http://www.ccsr.columbia.edu/population/map"]Columbia's Center for Climate Systems Research[/url].

Population
Action International (PAI) informs U.S. and international policy by
using research and strategic advocacy that firmly links population,
reproductive health, the environment and development – working to
strengthen political and financial support worldwide for population
programs grounded in individual rights. These strategies promise to
improve the lives of individual women and their families, while also
slowing the world’s population growth and thus helping preserve the
environment. Founded in 1965, PAI is a private, nonprofit group and
accepts no government funds.
