The counties of Kenya are geographical units envisioned by the 2010 Constitution of Kenya as the units of devolved government. The powers are provided in Articles 191 and 192, and in the fourth schedule of the Constitution of Kenya and the County Governments Act of 2012. The counties are also single member constituencies for the election of members of parliament to the Senate of Kenya and special women members of parliament to the National Assembly of Kenya. As of 2013 general elections, there are 47 counties whose size and boundaries are based on the 47 legally recognised Districts of Kenya. Following the re-organisation of Kenya’s national administration, counties were integrated into a new national administration with the national government posting county commissioners to represent it at the counties.
