Access Map

Low Access: Low income urban census tracts further than 1 mile from a retail location and low income rural census tracts with drive times >30 minutes to reach a retail location.

Limited Access: All census tracts not identified as Low Access with drive times >30 minutes to reach a retail location.

These maps show the results of an analysis establishing access to licensed cannabis retail establishments. Lack of access to licensed retail is partially correlated with the scale and location of the illicit market. The analysis illustrates the effect of local regulations, taxes, and fees on consumer access to licensed cannabis.

  • The County Access Tab shows the share of the county’s population living in low access areas. The map can be toggled to display the share of the population living in limited access areas, as well as the combined population share living in low or limited access areas.
  • The Census Tract Access Tab shows the access classification for individual census tracts. The map also displays the variables that determine their classification status including proximity to retail locations and income classification.
