Households in States with higher median incomes and lower poverty rates tend to have areas with healthier resources available, like good grocery stores, safe housing, opportunities to exercise, clean air, and better schools. In comparison, households in States with lower median incomes and higher poverty rates typically have less money to spend taking care of themselves, whether paying for visits to the doctor, medicine, or healthy food. Hence, these states appear to have relatively higher obesity and smoking rates. Additionally, stress associated with a lower income, especially during childhood, increases risk for heart disease, stroke, cancer, and diabetes.
Overall, the median age across the US appears to be in the 30-45 year range. Households in the 36-40 age range appear to have 26%-36% obesity rates. Interestingly, smokers started as early as 17.5 years based on the numbers for New Hampshire.
