In this Data-Driven Document (D3), the interactive data visualization shows some state-level data about three health risk factors (obesity, smoking and lack of healthcare) plotted against three perhaps underlying factors (income, poverty rate and age) based on 2014 U.S. Census Data.
The Chart was build using D3.js. Each marker represents an individual state in the US. Click on any of the axis titles to toggle different factors and hover on the circle marker to see more information!

Correlations Discovered Between Health Risks Vs Poverty, Age and Income

Health Risks and Poverty: Clearly, TX with a poverty rate of approx. 17.5% shows the highest percent of demographic that lack healthcare (25%). Also states with lower poverty percentage have significantly lower obesity rate. Smoking is prevalent in states with high poverty rate like WV, KY and MS.

Health Risks and Age: The chart clearly shows that people who lack healthcare fall between 36 to 40 years of age group. Also, Smoking rate is higher among adults between 36-42 years old. Adults in the age group 34-36 in TX also tend to lack healthcare.

Health Risks and Income: We can also conclude that overall healthcare improves with increase in median income. In general the states with median income above $65,000 have lack healthcare. Also, Lower income was consistently associated with higher smoking prevalence. States like WV, KY, AR and MS with lower median income have significantly higher smoking percentage.
