- We examine the characteristics of vendors, businesses, and the food environment.
- Vendors provide a variety of culturally acceptable food items to colonia residents.
- The variety of food items offered is related to the type of vending activity.
- Vendors' relative autonomy and oversight differs by the type of vending activity.
