A Map of All Americans! Visualization can often be an effective way to make sense of very large datasets. The Census Dot Map at http://demogra phics.coopercenter.org/DotMap/ displays the race and location of every American recorded by the 2010 Census; that's over 300 million data points displayed simultaneously on one map! If you were counted in the US Census in 2010, you can find your dot on the map! 

(a) Zoom out to see the entire United States. Which half of the country is more heavily populated, the East or the West?

(b) Zoom in to see the town/city your school is located in. (Click on "Add map labels" to help you find it.) Are there any noticeable racial/ ethnic patterns, with any areas predominantly populated by a particular racial/ethnic group? If so, describe one of these noticeable characteristics. If not, describe a noticeable characteristic about the population density in your town.
