^{^a}

Includes requirements that apply to all stores in the state or, if the state sets different requirements for small versus large or rural versus urban stores, the lowest level of requirements. States with requirements including multiple quantity measures are included in all rows in which their requirements could be coded. Two states could not be coded because they did not use a retail distribution model (MS) or because their stocking requirements were not quantifiable (IL).

^{^b}

Quantity refers to the minimum quantity (e.g., number of items, pounds, ounces, gallons) across all required varieties for each category. For example, “2 varieties; 2 containers each variety” would be coded as 2 varieties and 4 items.

^{^c}

Excludes breakfast cereal. Examples of common whole grain–rich food varieties include whole grain–rich bread, brown rice, whole wheat tortillas, corn tortillas, whole wheat pasta, and oatmeal.

^{^d}

Liquid varieties include whole, 2%, 1%, fat free, soy, lactose free, and ultra-high temperature.

^{^e}

Includes dried and canned beans, peas, and lentils.
