Research on the evolution of spatial pattern of population distribution and its influencing factors in Kenya
Based on the data of Kenya's four national population censuses,exploratory spatial data analysis,standard deviation ellipse,and population shift-share model were used to analyze the spatial pattern evolution characteristics of the population distribution of 47 administrative units in Kenya from 1989 to 2019.Then,this paper employed geographic detector to further ana-lyze the influencing factors.The results show that:① During the study period,the distribution pattern of population density in Kenya is relatively stable,showing high southwest and low northeast.② There are obvious spatial differences in population offset growth in different cities,mainly positive offset growth and negative offset growth types.And the population distribution center is northwest of the capital Nairobi and continues to migrate southeast.③ Natural and so-cio-economic factors jointly influence the spatial evolution pattern of population distribution in Kenya.Under the influence of elevation,climate,precipitation,economic development level and transportation infrastructure construction,the population is concentrated in a few areas along the southwest and southeast coasts of Kenya.Kenya has roughly formed a high-density popula-tion cluster centered on Nairobi,the national administrative center,Kisumu on the shores of Lake Victoria,and Mombasa,the largest port on the coast.
