The Immigrant Dot Map of America
Mapping Immigrant America is a dot map showing the number and origin of immigrants throughout the United States. Each dot on the map represents 20 immigrants and the dots are colored by the general region of origin. The data for the map comes from the 2009-2013 American Community Survey carried out at the census tract level.
If you zoom in on most cities on the map you can see how immigrants from the same general region of origin often seem to cluster in the same neighborhoods. The 'about' page contains more information about the data used and how the map was created. It also reveals that some navigational tools, such as a search option, are in the pipeline.
The Cooper Center's Racial Dot Map uses a similar methodology to map every person in the United States.
This map uses data from the 2010 US census, with each of the 308,745,538 dots on the map representing the location of one American. The Cooper Center's dot map however goes beyond being just a visualization of geographic distribution as it also visualizes the distribution of race and ethnicity in the United States.
