World Population Report: 'Aging Populations; Fewer Workers; Decline of Developed Countries': The 2010 World Population Data Sheet, published by the Population Reference Bureau (PBR) on July 28, says that a shrinking pool of working-age populations is jeopardizing social support and long-term health care programs for the elderly, and points to a decrease in the populations of developed countries.
In 1950, there were 12 persons of working age worldwide for every person age 65 or older. By 2010, that number had shrunk to 9. By 2050, this elderly support ratio, which indicates levels of potential social support available for the elderly, is projected to drop to 4.
The report also shows the contrasts between developing and developed countries and highlights that while developing countries will see populations increase, developed countries are beginning to see population shrinkage.
