This report is on population and demography of Kenya, prepared by Kenya National Bureau of Statistics. A census is the complete count of a country’s population conducted with the objective of providing information on the size, distribution, composition and other social and economic characteristics of a nation. Kenya has been undertaking censuses after every 10 years since 1969 and the 2009 Population and Housing Census was the fifth since independence and the seventh since 1948. The enumeration was conducted from the night of August 24th /25th with overwhelming support from Kenyans. The Kenya National Bureau of Statistics (KNBS) has worked tirelessly for the last 11 months to produce the results. This has been done in record time of one year after the enumeration exercise.
