World Population in 2050: Assessing the Projections
نویسندگان
چکیده
Joel Cohen was asked by the conference organizers to focus a critical eye on demographic projections and to give special attention to the outlook for the elderly and for total dependency ratios. He was very faithful to his assignment. I have only a few points to raise about his paper before going on to discuss one issue that he did not cover (and was not asked to cover) but that I think should be addressed as part of a comprehensive treatment of population prospects for the year 2050. The issue is the current youth bulge in many of the world’s poorest countries that have yet to reap the economic benefits of the demographic transition. First to Cohen’s paper.

متن کاملAssessing Climate Change Impacts: Agriculture
The economy-wide implications of climate change on agricultural sectors in 2050 are estimated using a static computable general equilibrium model. Peculiar to this exercise is the coupling of the economic model with a climatic model forecasting temperature increase in the relevant year and with a crop-growth model estimating climate change impact on cereal productivity. The main results of the ...
متن کاملDimensions of global population projections: what do we know about future population trends and structures?
The total size of the world population is likely to increase from its current 7 billion to 8-10 billion by 2050. This uncertainty is because of unknown future fertility and mortality trends in different parts of the world. But the young age structure of the population and the fact that in much of Africa and Western Asia, fertility is still very high makes an increase by at least one more billio...
متن کاملProjection of populations by level of educational attainment, age, and sex for 120 countries for 2005-2050
Using demographic multi-state, cohort-component methods, we produce projections for 120 countries (covering 93% of the world population in 2005) by five-year age groups, sex, and four levels of educational attainment for the years 2005-2050. Taking into account differentials in fertility and mortality by education level, we present the first systematic global educational attainment projections ...
