The data for this visualization comes from the American Community Survey which is conducted by the US Census Bureau. The data was downloaded from American Fact Finder. It is found under Table S2701, of the 2014 1 Year Estimates. It is important to note that the numbers do not total to the population because a person can have more than 1 type of insurance.
After the data was acquired, it was cleaned in excel. The visualization was then created in Tableau.
