This gallery of map contains seven kinds of maps:

  • Basic income and population density maps on standard geographical objects such as census tracts, zip codes or counties;
  • Concentric circle analysis where the distance is given and the population is solved for;
  • Buffer analyses where the population is given and the geographical area containing the population is solved for;
  • “Area of influence” analyses where a new program/business is placed in the middle of existing programs and the population that lives closest to the new program is solved for. This is a powerful and little known technique that identifies the size of the population closest to the new program. Once you know the sixe of this population you can make estimates as to how many are likely to use the new program;
  • Network adequacy studies where the spatial distance between providers and beneficiaries or customers is examined;
  • Zip code analyses showing where a business or program’s users come from, and
  • Irregular-shaped hand-drawn map areas where the demographics of the hand-drawn area are estimated.
