Population | World Population Honeycomb Map-Built with stats from the 2004 CIA Factbook, it will certainly help you better grasp the relative population, geographic area, and density of the world's biggest countries. Each square represents a country. You control how the countries are grouped within the Honeycomb, what data is represented by the size of the square (population, size, or density) and what is represented by the color of the square. Clicking on any square will display the country's quick facts, along with a link to its Wikipedia entry.
Made in the U.S.A Clicking on any state will reveal population changes expected there. "North Dakota is the only state that is expected to decline in population." To scroll backwards through history, click on the timeline at the bottom of the graphic, or use the Previous button. Note changes in our racial profile (see the graph on the right), and population density. Just above the timeline, are audio clips about the corresponding generations, including The Lost Generation, Baby Boomers, Gen X, and more.
