The data for this visualization comes from the American Community Survey which is conducted by the U.S. Census Bureau. I used the Census Bureau API to pull the 2016 5 year estimate for the percentage of the population that is foreign born. Once I had gathered the data, I used Tableau to create this visualization.
I have included the API code I used to pull the data below. You will need a free API key to access the data. You can find out more at the Census Bureau’s Developer Page.
