World Population: 2020 Overview. YaleGlobal. Joseph Chamie. February 11, 2020
Understanding global demographic trends is essential for government and business planners, offering insights into resolving numerous challenges. World population growth is slightly ahead of what was projected a few years ago, reports demographer Joseph Chamie. More than half the world lives in urban areas today, and that is expected to rise to 70 percent by 2050. Most population growth will continue in less developing nations while advanced economies experience population declines and greater proportions of elderly citizens due to increased life expectancy and reduced fertility rate. Chamie explains that more than 80 countries, half the world’s population, now post fertility rates below the replacement level. That leaves fewer workers available to support each individual over age 65, compelling governments and individuals to prepare for long retirements. Good planning can also prevent a variety of other hardships including food and water shortages, poverty, environmental degradation and even security crises. In 2011, former UN Secretary-General Ban Ki-moon pointed to the value of demographics and planning. “We cannot look at one strand in isolation,” he said. “Instead, we must examine how these strands are woven together.” [Note: contains copyrighted material].
