-In general, the distribution of mammography clinics throughout Pennsylvania is proportional to the

population of females between the ages of 40-74.

-There is a noticeably high concentration of mammography clinics in Pittsburg and Philadelphia, to serve

the large populations in these urban centers.

-One area where the number of clinics appears inadequate to the population is Venango County where

there is only one clinic to serve the entire county and it is not located centrally to the zip codes with a

higher female population.

-Below are the zip codes containing the largest female populations age 40-74 and the number of clinics

that correspond to each:

Zip Code Location Female Population (40-74) Number of Clinics

19143 Philadelphia 15016 1

17055 Mechanicsburg 12476 2

18103 Allentown 12360 0

19111 Philadelphia 11418 2

-While some of these zip codes appear to have an inadequate number of mammography clinicsall of

these zip codes are located near areas with a high concentration of mammography clinics.

-Zip code 18103, located in Allentown, has no mammography clinics, but two adjacent zip codes have 2

clinics each.

-Two zip codes in Philadelphia appear in this list twice, with one zip code only having 1 clinic, but overall

Philadelphia has a high concentration of mammography clinics.
