Comparability — General

Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time.

• North and South Rift Valley provinces are identified separately in the 1979 and 1989 samples, but in all other years they are combined as the Rift Valley province.

Kenya passed a new constitution in 2010 which nullified all geography changes that occurred after 1992. As a result, the former Provinces were abolished, and the former second level administrative units, formerly Districts, were elevated to the new first level administrative units and renamed Counties. The 47 districts present in 1992, with the same boundaries present at that point, now represent the 47 counties that make up the first geographic level. Despite the former provinces now holding no administrative role, provinces are still used as the level of geography identified in BPL1_KE to preserve comparability between samples.
In the 1989 sample, this question was only asked to non-visitors and long-form respondents. In later samples, the universe is all persons.
