The correlation seen between the unemployment rate and the rate of preventable hospitalizations was very high (0.87).
The correlation between the unemployment rate and the rate of avoidable emergency department visits was very high (0.81).
These results suggest a strong relationship between unemployment rate and the quality of healthcare options available to citizens. As unemployment rate increased, so did rates of preventable hospitalizations and emergency department visits. This in turn indicates a decrease in quality of care. This suggests that Chicago zip codes in which unemployment rates are high also experience a lower quality of care from providers in their area.
Things that need more investigation include whether a similar trend exists with geographical and financial access to healthcare, along with how this trend relates to population and income levels.
We found was that there was a pretty strong correlation between median household cost and median hospital costs which is lower household income gets you lower hospitalization costs. This could mean that some families with lower incomes get charged less, have less reason to be hospitalized, or just go to the hospital less because they can’t afford it.
