How does the concentration of dollars stores correlate with various socio-economic factors? Here are some interesting results from a study featured in The Atlantic:
1. The correlation between dollar stores and median income is significant and negative (-.57).
2. Dollar stores are concentrated in states with lower levels of education or human capital. The correlation is again significant and negative, even greater than for income (-.77).
3. The geography of dollar stores also tracks to the country's political divide. Dollar stores are positively correlated with the share of voters who backed McCain (.52) and negatively associated with Obama voters (-.47).
4. Obesity, smoking and crime also come into the picture. They are positively associated with the percentage of adults whose body mass index is greater than 30 (.72) and the percentage that smoke (.6).
5. Dollar stores states are also positively associated with property crime (.34), especially burglary (.54), and violent crime (.3), especially murder and manslaughter (.49).
6. Religion too plays a role. Dollar stores are positively and significantly associated with the percent of people who say religion plays an important role in their daily life (.71).
