These graphs break down the flow of immigration, looking at people who became naturalized U.S. citizens in fiscal year 2012 (the most recent data available). Most people would be able to guess that the plurality are from Mexico, but they make up fewer than one in seven of the 757,434 people who were granted citizenship!

Using the graphs, you can see where the people came from, which state they now reside in, and what the 20 most common pathways are (from a single country to a single state). You can also identify the most common birth country of newly naturalized citizens in your state; these are labeled to the right of the bars in the second graph.
