This paper aims to calculate the rates of Chlamydia infection at genitourinary medicine (GUM) clinics in England. Data on the number of cases is available from KC60 returns from GUM clinics in the Northwest and Southwest of the country, but the population exposed to risk is required in order to calculate rates of infection. This study tests three different methods of deriving the exposed to risk: Thiessen polygons, 15 mile boundaries, and 30 minute drive-times. It was found that the method of deriving the population exposed to risk did not significantly affect the Chlamydia rates. Thus the best choice of method was deemed to be the simplest approach, the Thiessen polygons. The 15 mile and 30 minute drive-time models did, however, highlight substantial differences in the accessibility of GUM services between the Southwest and the Northwest.
