The Demographic Observatory 2014 contains selected indicators from the 2014 revision of estimates and projections for the populations analysed. The figures contained in this publication are a revision of those presented in the Observatory 2013 and include updates of the estimations and projections of national populations from 1950 to 2100, taking into account new information sources available. Future issues will incorporate new estimates and projections, also prepared using the component method, but by simple ages and calendar years.
