Prepared by: Stella Kim
Hospital Location Implications for Health

Hospitals are heavily clustered in wealthier counties
Median income varied from $36k in Modoc County to $94k in Marin County
Los Angeles County on the higher side of median income at $58,611

In densely populated counties, most can access hospitals coverage of the entire county is generally within 10 miles
Rural counties have less hospitals and their ranges don’t meet

Health Risks: Diabetes Incidence and Uninsured Populations
The CDC estimates that in the US, 8.3% of the population is currently diabetic¹
In California the diabetic rate ranges from 8% to 10%
National uninsured rate was 15.7% in 2011 of 311 million people according to the US Census ²
California’s counties ranged from 12% in Marin County to 25% in Los Angeles County

Methodology: County Health Rankings
County Health Ranking Project funded by the Robert Wood Johnson Foundation ¹
Ranks counties based on Health Factors, tobacco usage, sex, diet, access to care, quality of care, income, employment, education and environment
Also ranks counties based on health outcomes including morbidity, mortality, health behaviors, clinical care.

FINDINGS & NEXT STEPS
FINDINGS: Median Income breakdown of counties are very
similar to County Health Rankings with wealthier and higher ranked counties having the most hospitals and access of care
Counties with high incidence of diabetes, and uninsured populations are lacking in hospital service.
Additional variables and data must be examined to better compare LA County’s health status and hospital utilization as a possible factor for the final
SKILLS UTILIZED

Challenges
CHALLENGES: GIS steep learning curve, DATA DATA DATA, finding it and manipulating it. Lack of actual hospital utilization data put further query at a standstill
FURTHER QUERIES: Thorough examination and hunting of original data for an innovative project
