A good example of a food desert would be an inner-city neighborhood, the first time I heard this term, they were talking specifically about places in Oakland, CA. Which ironically is a short train ride away from the Food Mecca of the USA.
> There are no set few factors, but some other influences that affect food deserts may include: mobility, existing health issues, working irregular hours, fast food culture, lacking adequate knowledge about nutrition, and many more.
Seems like the qualifications are whatever they want them to be.
