Abstract
The widespread informal settlements in Nairobi have interested many researchers and
urban policymakers. Reasonable planning of urban density is the key to sustainable development.
By using the spatial population data of 2000, 2010, and 2020, this study aims to explore the changes
in population density and spatial patterns of informal settlements in Nairobi. The result of spatial
correlation analysis shows that the informal settlements are the centers of population growth and
agglomeration and are mostly distributed in the belts of 4 and 8 km from Nairobi’s central business
district (CBD). A series of population density models in Nairobi were examined; it showed that
the correlation between population density and distance to CBD was positive within a 4 km area,
while for areas outside 8 km, they were negatively related. The factors determining population
density distribution are also discussed. We argue that where people choose to settle is a decision
process between the expected benefits and the cost of living; the informal settlements around the 4-km
belt in Nairobi has become the choice for most poor people. This paper ends with suggestions for
urban planning and upgrading informal settlements. The findings will increase our understanding of
urban population distribution in underdeveloped countries.
