Province maps of Kenya showing: A) areas in 2003 that were within the 5 km benchmark of geographic access to public health services recommended by the ministry of health*; B) areas in 2008 that were within the 5 km benchmark of geographic access to public health services recommended by the ministry of health*; C) percentage increase in population within 5 km of a public health facility from 2003 to 2008**; and D) number of people in 2008 that were outside the 5 km benchmark to public health services***. Geographic access is represented as Euclidean (straightline) distance to public health facilities. 390 service providers that were not spatially positioned and all specialist facilities that do not provide services to ambulatory patients (72 in 2003 and 67 in 2008) were not included in the computation of distances to health facilities. *11% of the population was outside 5 km of a public health facility in 2008 compared to 29% in 2003. **The highest percentage increase in public health facilities in 2003–2008 occurred in areas in North Eastern province (Table 2). Most areas in this province, however, also registered the lowest proportional increase in population within 5 km of a public health facility in the same period. ***Several of the large, sparsely populated areas of northern part of the country had 100,000 or more people of the population outside of a 5 km of a public health facility accounting for 80% of the population in some of these areas. Areas within provinces in 2B and 2C represent the districts as at December 2007 (n = 69). Since then the number of districts have increased to 149 but the digital boundaries these new districts were not available at the time of the study.
