Beyond Six Billion

Beyond Six Billion's seven chapters assess population projections, including demographic variables such as fertility, mortality, migration, and the uncertainty of population forecasts and forecast errors. Other population topics with assorted humanitarian, civilizational, or environmental implications, such as carrying capacities, limiting factors, and overshoot or collapse ramifications are largely, or in some cases entirely, absent, so that readers interested in the latter issues will need to turn to other sources.
