The data for this visualization comes from the National Center for Health Statistics which is managed by the Center for Disease Control and Prevention. I gathered data from multiple PDF reports to compile this data set. Once I gathered the data, I used Tableau to create this visualization.
It should also be noted that the percentages don’t add to 100%. The data for households with both or which wireless status couldn’t be determined wasn’t included because of a methodological change in 2007.
