SOURCE: Adapted from United Nations Population Division, The World at Six Billion. (ESA/P/WP.154).1 NB: Population growth seems to affect everything but is seldom held responsible for anything. Some of the key reasons for this predicament are (1) growth is invisible from day to day; (2) there is "scale paralysis," a sense of powerlessness in response to the size of the problem; (3) many people are unable to comprehend such large numbers; (4) population growth is never an immediate political problem, but only a long-range one, and thus can be put off; and (5), last but not least, the subject is often controversial and divisive.

NOTE: 1. See United Nations Dept. of Economic and Social Affairs, Population Division, World Population Prospects: The 1998 Revision (New York: United Nations, 2000), United Nations Dept. of Economic and Social Affairs, Population Division, World Population Projections to 2150 (New York: United Nations, 1998).
