U.S. Projected to Remain World's Third Most Populous Country Through 2050, Census Bureau Reports

PR Newswire

WASHINGTON, June 27, 2011

WASHINGTON, June 27, 2011 /PRNewswire-USNewswire/ -- Through 2050, the United States is projected to remain in third place behind India and China among the world's most populous countries, according to the U.S. Census Bureau. These findings are derived from the population estimates and projections for 228 countries and areas released today through the Census Bureau's International Data Base. This release includes revisions for 19 countries and provides information on population size and growth, mortality, fertility and net migration.


"The Census Bureau has been preparing individual country population estimates and projections for more than 50 years," said Loraine West, a demographer in the Census Bureau's Population Division. "Current estimates and projections are provided through 2050 and are routinely updated as new data become available."

Although the United States will maintain its third place position, the ranking of the countries with the 10 largest populations in the world (see table) is expected to change over the next few decades.

The top 10 countries each currently have at least 125 million inhabitants. Russia and Japan are projected to soon fall out of this group because of persistent low fertility rates, which have already caused their populations to decline. Russia's decline is also due in part to relatively high mortality.

The countries expected to advance in the rankings are those with high fertility. Ethiopia, in particular, with an estimated fertility rate of 6.0 children per woman in 2011, is projected to vault from 13th to seventh on the list of most populous countries by 2050, tripling in total population from 91 million to 278 million. Nigeria also has a relatively high estimated fertility rate of 5.7 and is projected to more than double its population by 2050 from 166 million to 402 million.

Currently seventh on the list of most populous countries, by 2050, Nigeria is projected to climb to fourth.

Other developing countries, such as Bangladesh, Brazil and Indonesia, while continuing to grow, will drop slightly in the rankings given that their fertility already is lower than Ethiopia and Nigeria.

China and India, the only countries with more than a billion people, are expected to continue to occupy the top two positions, although their order is projected to switch by 2025 when India is expected to overtake China as the world's most populous country.

By 2050, the Philippines will round out the world's most populous countries, reaching 10th on the list with a projected population of 172 million.

The 19 countries included in this update are Afghanistan, Angola, Azerbaijan, Comoros, Curacao, French Polynesia, Japan, Kazakhstan, Kenya, Liechtenstein, Moldova, Netherlands, Nigeria, Qatar, Singapore, Sint Maarten, Suriname, United States and the British Virgin Islands.

The Census Bureau's International Data Base includes projections by sex and age for countries and other areas with populations of 5,000 or more. Population projections incorporate assumptions about future trends in fertility, mortality and migration. In general, fertility and mortality are projected based on recent trends and migration for each country typically reflects recent trends but also considers longer-term levels of migration. The level of uncertainty is greater for projections further in the future.

Unprecedented Int'l Meeting Releases Preliminary Vision for our Energy Future

WATERLOO, Ontario, June 9, 2011/PRNewswire/ --

- Global Energy Summit in Waterloo, Canada Offers Ideas for Action on Sustainable Low-Carbon Electricity

A unique, international summit of scientists, engineers, entrepreneurs and future leaders from around the world has concluded with the release of the Equinox Summit: Energy 2030 Communiqué. The event's preliminary report includes visionary proposals for transformative action to reduce the electricity-related emissions that drive global warming.

The full Equinox Communiqué is now available at:

The Communiqué identifies a group of technological approaches and implementation steps that have the potential over the coming decades to accelerate the transition of our energy systems toward electrification and, in the longer term, toward an energy future where our dependence on fossil fuels is greatly reduced.

"Given the right support, the six priority actions we have identified can catalyze change on a global scale, from the cities of the developed world, to the billions of people who live in towns and villages that lack adequate access to electricity to provide the central link to improvements in the quality of life," said summit advisor Professor Jatin Nathwani, Executive Director of the Waterloo Institute for Sustainable Energy at the University of Waterloo and Ontario Research Chair in Public Policy for Sustainable Energy.

Can we low-carbon power the planet in 20 years?

Equinox Summit: Energy 2030 participants came together to intensely explore, discuss and propose how science and technology can catalyze the urgent change required.

With representatives from countries including Canada, Brazil, China, Costa Rica, Indonesia, Nigeria, the USA, and more, the Equinox Summit embodied the realities, challenges, and hopes of the enormously diverse global community - from those living in the world's 21 mega-cities of more than 10-million inhabitants, to the one-third of humanity who survive without electricity.

An electricity roadmap for nations

The Equinox Communiqué is a brief snapshot of the ideas and visions developed by the Summit participants, who aimed to address the great complexity of transitioning to low-carbon electricity production. It provides a series of immediate, concrete opportunities for action by industry and governments, both locally and internationally. These ideas will be explored in more detail in a future document, the Equinox Blueprint: Energy 2030.

The pathways described in the Communiqué include: accelerating implementation of technologies to enable the integration of large-scale renewable sources of power, such as wind and solar, into existing electricity grids; new ways to develop low-carbon transportation; ways to build energy-smart cities; and means of providing sustainable electricity to those who currently live without it.

The Equinox Communiqué compliments a comprehensive online video resource of archived lectures and discussions by world-leading thinkers on achieving a low-carbon, sustainable electricity future.

That resource includes:

- Summit participants expanding on their closed-door discussions in public forums (

- The Summit's infographic-style benchmark clips (

- A photo-diary of the week's accomplishments (

What's next

The ideas outlined in this Communiqué will form the basis of a detailed document that will be produced in coming months - the Equinox Blueprint: Energy 2030.

Equinox Blueprint: Energy 2030 will paint a picture of the challenges faced by society in energy, detail forecasts from various global and national agencies for the likely state of affairs in 2030, and list the Equinox Summit's recommendations and proposals to address these.

Equinox Blueprint: Energy 2030 will be aimed at informing, advising and inspiring science and technology influencers, industry leaders and governments globally. It will focus on how science and technology can contribute to the challenges faced. It will offer practical, real-world solutions - based on the latest scientific thinking - and offer recommendations for investment and focus, and for the coordination of national and international scientific and engineering efforts which may, over the next 20 years, help address energy challenges in a meaningful way.
