KPHC Analytical Report on Population Projections 2009

The projected size, composition and distribution of the population at different geographic units and points in time form a rational basis not only to gauge the primary needs of the Kenyan population, but also plan for these needs accordingly. This volume presents various components of population projections based on the 2009 Kenya Population and Housing Census in four chapters. The Accuracy Index for the 2009 census was 23.7, which is fairly accurate, as it is on the lower scale of 20-40. Comparatively, the 2009 census had the best Accuracy Index followed by the 1989 census, with the 1979 census recording the worst at 28.1. Once again, data from North Eastern province reflected highly inaccurate reporting with an index of 108 (with 20 as the cut off point) followed by Nairobi province (64) in this category. Only Western province – with an index of 18 – fell in the category of accurate reporting. The rest of the provinces had indices that placed them in the category of inaccurate.
