Issued in December 2001, the Census Bureau released its latest report on global aging entitled An Aging World: 2001. This publication updates and expands on previous Census Bureau reports that focused on past, current, and projected numbers, proportions, and growth rates of the elderly population worldwide. Recognizing the characteristics of the elderly are increasingly heterogeneous among and within nations, a second objective of An Aging World: 2001 is to summarize socioeconomic statistics for both developed and developing nations. This report highlights such data for 52 nations when information is available and reasonably comparable.
