This dataset shows the number of people per square kilometer around the world in 1994. The data were derived from population records based on political divisions such as states, provinces, and counties. Because the
resolution of the data from different nations varies, some small areas with high populations (such as Rio de Janeiro, Brazil) appear to have moderate population density spread over large areas.
For the past few decades, Africans have been moving from rural areas into cities, seeking work. The continent’s urban population has skyrocketed. Nairobi is a prime example of that migration, with its population pushing upward and its boundaries pushing outward.
