- 2. The 2003 Revision presents estimates and projections of the total, urban and rural populations of the world for the period 1950-2030. The results are shown for development groups, five major areas (Le., Africa, Asia, Europe, Latin America and the Caribbean, Northern America and Oceania) and 21 regions…
- 3. Data are further disaggregated for the 228 countries or areas of the world. Almost all population growth expected for the world in the next thirty years will be concentrated in the urban areas. The smaller urban settlements (with fewer than 500,000 inhabitants) of the less developed regions will be absorbing most of this growth. Mega-cities, like Tokyo, Mexico City and New York will continue to dominate the urban landscape in some countries, but the majority of the urban dwellers will be residing in the smaller cities.
- 4. Human population history may conveniently be divided into four eras or periods: The First Era (Paleolithic or Old Stone Age): began about 1 million years ago The Second Era (Beginning of Agriculture): began 10,000 years ago The Third Era (time of transition between the culmination of the Agricultural Revolution and the inception of the Industrial Revolution): roughly from 1000 AD to 1750 AD Fourth Demographic Era (After inception of Industrial Revolution): after 1950 AD. The rapid upturn in population occurs earliest during 1750-1850 in Europe, Anglo American, the Caribbean, the Indian subcontinent and China Other areas followed around 1900, and by 1950 Source: Trilochan Pokharel
