Question: I am researching the relationship between fast food restaurant and obesity (both per capita in large US cities). So far, we have difficulty in finding information for specific cities. I was wondering if you had any suggestions of where we could look.
Answer:
If there is some flexibility on the locations and time periods, there are several sources to use. Here are two options that seem like they would work well for the current need.
For obesity statistics, the Behavioral Risk Factor Surveillance System (BRFSS) Local Health Risk Prevalence Data - City and County Data is a possible source
For the number of fast food restaurants, the economic census is the most authoritative source:
2002 Economic Census: Geographic Area Series (Metro areas, counties and places)
use "Limited-Service Restaurants" or NAICS 722211 in the "Accommodation and Food Services" sector.
