animated demographic stats
The Asian Studies WWW Monitor recently profiled a go-to site for understanding basic demographic data and coming changes in China. Gerard K. Heilig has an impressive body of work that presents data on Chinese demographics, fertility, land use, and food production, through animations, CD-Roms, and maps. Heilig’s homepage links to some of his publications, such as Can China Feed Itself: a System for Evaluation of Policy Options, which contains data on three different models for projecting China’s urban population in the next several decade.
His latest effort, China-Profile, contains a range of data (such as figure above, Population by Age and Sex in 1990) on human development, natural resources, policy, economy, science & technology, infrastructure, and culture.
