    • Description:
      In April 2011, the CDC’s Division of Nutrition, Physical Activity and Obesity released the Children’s Food Environment State Indicator Report, 2011. One indicator featured in the report is the modified retail food environment index (mRFEI). The mRFEI measures the number of healthy and less healthy food retailers within census tracts across each state as defined by typical food offerings in specific types of retail stores (e.g., supermarkets, convenience stores, or fast food restaurants).

      Out of the total number of food retailers considered healthy or less healthy in a census tract, the mRFEI represents the percentage that are healthy.While the

      report includes median mRFEI values for each state, there is substantial variability in the retail food environment within states. The maps included in the current release provide a useful starting place to identify specific geographic areas of states that could benefit from further examination of the retail food environment. The maps can identify census tracts that either lack access to healthy food retailers such as supermarkets or contain very high densities of fast food restaurants and convenience stores relative to the number of healthy food retailers.
