World and regional population growth.
In 1978 the United Nations Population Division reassessed world population estimates and projections in light of data that became available after the previous assessment of 1973. In this report the 1973 figures and the 1978 figures are compared with respect to base population, growth rate, and projections for the latter half of the 20th century. According to the 1978 assessment the population growth rates projected in 1973 were too high for both developing and developed countries, and the world population growth rate has been declining since the 1960s rather than rising as previously thought. However, the revised estimate of 1975 world population is higher by 65 million than the previous estimate, so the projection for the year 2000 is only slightly lower than before in spite of lower growth rates. The 1973 and 1978 assessments for major areas in developed and developing regions are tabulated and discussed.
