Interpretation and Geographic Equity Analysis

The Chinatown, Presidio Heights, Nob Hill, North Beach, and Russian Hill neighborhoods have the highest concentration of supermarkets per square mile. Seven neighborhoods have no supermarket, including: Treasure Island, Presidio, Pacific Heights, Ocean View, Crocker Amazon, Visitacion Valley, and Twin Peaks. While Pacific Heights and Visitacion Valley do not have a supermarket, both neighborhoods have at least one smaller grocery store and Crocker Amazon has two produce markets and a meat market.

The Food Market Score indicator combines the quality, quantity, and proximity of all retail food resources near any one point. Stores receive a distance penalty when they are further than a quarter mile away. A high Food Market Score indicates that a neighborhood is geographically close to a range of different food store types. A score cannot reveal whether the stores that are nearby are affordable or that they have high quality stock; thus, a high food market score indicates that the physical infrastructure is present for a diverse food retail environment. Neighborhood averages for the Food Market Score shows that Downtown/Civic Center, Nob Hill, Chinatown, Financial District, and Castro/Upper Market, Mission, Haight Ashbury, and Russian Hill have the highest Food Market Scores. Treasure Island, Visitacion Valley, Lakeshore, Presidio, Seacliff, and Bayview have the worst scores.
