Competitive spatiotemporal dataset on population distribution and its natural-social-economic driving factors from 1949 to 2013

DOI:10.3972/card.002.2015.db Submitted Date: 2016-05-27 Published Date: 2015-07-26

Spatiotemporal data of human populations and its driving factors including environmental factors and social and economic conditions, is critical in order to better understand and respond to the population problems. Unfortunately, spatiotemporal data on populations and their driving factors on a large scale and over the long term are often difficult to obtain directly. We present a dataset on the C...
