World population projections : 1989-90 edition : short- and long-term estimates

This volume contains population projections for the world and its subdivisions - countries, regions, and income groups. The projection results, which are presented in the detailed tables that comprise the main section of the book, are explained, summarized, and interpreted in the introductory section. Also described in the introduction are the base data and the project methodology, which has been revised since the last edition. Summary tables on population size and growth, age structure, fertility and mortality rates, the world and the continents, geographic regions and income groups, World Bank regions, and individual countries are included. The tables on age structure cover broad age groups (0-14, 15-64, and 65 and over) and provide a more convenient summary than did previous editions. The projections cover the entire world for almost two centuries, from 1985 to 2150. With data available as of mid-1989, separate projects were prepared for 187 countries, economies, territories, and small-country groupings. The length of the projection period was chosen to allow populations to approach stability, which in some cases takes essentially the entire period.
