Population Analysis, by Warren Munroe

what's happening?

The estimated number of people living on Earth has been revised upward. The world population will likely reach 7 billion in October 2011 rather than in 2013 (UN estimate, May 3, 2011)

By 2050, the number of people could reach approximately 8.1 billion (low fertility scenario) or 9.3 billion (medium fertility) or as high as 10.6 billion (high fertility).

If low fertility were to continue to 2100, the number of humans could decline after 2050 to 6.2 billion

Some areas are experiencing rapid growth while the population in other areas is declining.

Environmental conditions are changing. How will we manage?

Here you will find out how Population Geography can help provide insights.

Welcome

Population Analysis provides the foundation upon which to examine human to human interaction in relation to human interaction with the environment.

The number of people by age and sex, the number of births and deaths, and the number of migrants in and out of areas, by their age and sex, forms the basis upon which social and economic activity are examined.

Historical population estimates are referred to in relation to current estimates and short, medium, and long range forecasts for areas within Vancouver island, on the West Coast of British Columbia Canada, to total World population and places in between.

Main sources for population numbers used are the United Nations and Statistics Canada. The methods and models used are also examined in an effort to understand the strengths and weaknesses of the population estimates and forecasts.

Population analysis benefits from contributions from the disciplines of Population Geography and Demography.
