Falling birth rates and world population decline: A quantitative discussion (1950-2040) [PDF]

, 2013
The UN data (1950-2010) and projections (both medium and low-fertility variants for 2015- 2040) show that fertility rates are already below replacement level in all continents except Africa. In this paper we develop a simple new approach for population
