Street food stands (SFS) are an understudied element of the environment. Previous SFS studies have not used a rigorous approach to document availability, density, and distribution across neighborhood income levels points access in Mexico City. A random sample (n = 761) street segments representing 20 low-, middle-, high-income neighborhoods were assessed using geographic information system (GIS) ground-truthing methods. All three contained SFS. However, availability density higher...
