In an earlier post we mapped the urbanization rate of China at province level. In this post we will go futher by visualizing where Chinese people are living using a gridded population map. We will use the NASA dataset (Population Density Grid, v3 (1990, 1995, 2000)) which consists of estimates of human population by 2.5 arc-minute grid cells. A proportional allocation gridding algorithm, utilizing more than 300,000 national and sub-national administrative units, is used to assign population values to grid cells.
In this article we are going to plot a map of China urbanization rate per provinces together with Chinese cities with at least 2 millions population. In a nutshell, we’ll get first rural and urban population data from official China statistic bureau, then clean the data, we’ll repeat the same two steps for Chinese largest cities. Secondly, we’ll prepare a map of China with provinces. Then we will add the main Chinese cities and their population and a choropleth of urbanization rate, add main cities
