PIP: The United States Population Data Sheet (Population Reference Bureau, 1994), 11th edition, lists information by state concerning crime rate, acquired immunodeficiency syndrome (AIDS), demographic aging, and expected population growth. Crime rates for 1992 were highest in the District of Columbia (11,407 serious crimes--murder, aggravated assault, burglary, arson, and rape--per 100,000), Florida (8358), Texas (7085), Arizona (7029), and California (6680). They were lowest in West Virginia (2610), North Dakota (2903), South Dakota (2999), New Hampshire (3081), and Kentucky (3324). The states with the highest crime rates were more urban. The rates of new, reported AIDS cases, which have more than doubled because of changes in the definition of AIDS by the Centers for Disease Control and Prevention (1993), range from 274 per 100,000 in the District of Columbia, 96.0 in New York, 79.9 in Florida, 69.0 in New Jersey, and 59.9 in California to 1.7 in North Dakota. The lowest rates are found in Montana, South Dakota, West Virginia, and Idaho. The rate for the United States is 40.1. Age structures are dramatically different among the states. 4.3% of the population of Alaska (the youngest state) are age 65 or over; 18.6% of Florida (the oldest state) are. The ratio of births to deaths (another measurement of population aging) in 1993, for the United States, was 182/100. West Virginia, Pennsylvania, Florida, Arkansas, and Maine have ratios less than 140/100. Alaska, Utah, Hawaii, California, and Texas rank above 240/100. Overall, the population of the United States is expected to grow 25% by the year 2020 (Census Bureau). Growth is expected to be most heavy in the Sunbelt. The population in the West is projected to grow by 50%; that in the South should grow by almost 33%. California, Nevada, Washington, and Hawaii are projected to grow by more than 50%. West Virginia, New York, Pennsylvania, Ohio, Iowa, Rhode Island, Michigan, Connecticut, and the District of Columbia, the slowest growing states, are projected to grow by no more than 10%.
