To do this, in the calculations and analysis carried out in this document (unless otherwise specified) the Centre region should be understood as “the Centre region excluding Yaounde” and the Littoral region as the “Littoral region excluding Douala.” In the ECAM survey, urban areas include cities with at least 50 000 inhabitants; all other localities are considered as rural. According to this logic, 36.24% of Cameroonians were urban in 2007 across the entire population, while this figure was 30.7% for children aged 0 to 14. In the general census, however, any town with over 5000 inhabitants and all towns which were the administrative centre for a county were considered as a city.
