Data from the Census Bureau & Bureau of Labor on Google
This is a pretty powerful device that Google has just added to their array of tools. Anything you can think of on populations in the US can be made into a simple chart as you can see above from mine where the unemployment rate in the US is compared to Virginia and my home county of Fairfax. Below that is a video explaining the tool. You can get information on all of the following:
CO2 emissions per capita, Electricity consumption per capita, Energy use per capita, Exports as percentage of GDP, Fertility rate, GDP deflator change, GDP growth rate, GNI per capita in PPP dollars, Gross Domestic Product, Gross National Income in PPP dollars, Imports as percentage of GDP, Internet users as percentage of population, Life expectancy, Military expenditure as percentage of GDP, Mortality rate, under 5, Population, and Population growth rate.
