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.
Objective 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 : 1 - Get rural and urban population data from official China statistic bureau, clean the data, same two steps for Chinese largest cities 2 - Prepare a map of China with provinces 3 - Get data for the main Chinese cities, population, names and longitude, latitude 4 - Plot China base map with provincial subdivisions, choropleth of urbanization rate, add main cities
