I. Quick overview of global patterns

In class, I handed out copies of the World Population Data Sheet. The data sheet gives information based on mid-2013 statistics for the entire world, and broken down by subregions of the world and individual nations.

The address for ordering it, should you wish a poster-format version, is on the supplementary reading list for this unit (click here on study guide to move there now). The fact sheet is produced by the Population Reference Bureau, which is a standard reference for data on population. You can access the web site for the PRB by clicking on "PRB." The site includes sample portions of the fact sheet, a population "Jeopardy" game, and addresses and links for many other population-related sites, including the US Census Bureau, the United Nations, and others. (If you visit this site from here, and then want to return to these notes, just click the box labeled "BACK" in the tool bar near the top of your screen.) You can access the United Nations population web site by clicking on UN.

Data on US population from the US Census Bureau are available at the Census Bureau's home page. Click on "census" to jump there now (and remember about using "BACK" to return to here from there!)

Another site with useful population-related information, including addresses for other sources is produced by the organization Population Connection (formerly called Zero Population Growth). This site can be accessed by clicking on "ZPG."

You can see real time population counts happen -- including births and deaths -- at a site that I'll show in lecture, but which you can also access from here.

Finally (although many more sites could be listed!), Population Action International maintains a web site providing information on population and environmental issues.

(**************Note: If you find that any links I give in these pages are no longer active, please let me know so that I can update them! Thanks very much.******************)

Let's look at some world data using the fact sheet given in class.
