The crime rate in the U.S., which rose dramatically in the 1960s and 1970s, has gone down steadily. Department of Justice statistics show that serious crimes (murder, rape, robbery, etc.) declined 7 percent and an additional 4.5 percent the following year. In some areas, for example in New York City, crime decreased 17 percent over a three-year period, with homicides and burglaries down by 10 percent. However, experts who had predicted a further decline were puzzled when FBI figures for 1985 showed an increase in violent crimes.
Public opinion polls show that Americans view crimes as one of the most serious problems of their society. Several studies have also shown that the amount of crime, especially violent crime, is frequently overestimated. Experts believe that this awareness and fear of crime is largely caused by the great attention it is given in newspapers and on television, and also because violent crime is a popular theme for television series and films. Many Americans are therefore surprised to learn that, according to Interpol, the "general crime rate per 100,000 inhabitants" for the U.S. is significantly lower than that for several other western nations such as Sweden, New Zealand or Denmark, and not much higher than those for Germany, Aus¬tria, or England.
Nevertheless, among all crimes, murder makes the headlines, and there is no doubt that homicides continue to be a serious problem in America.
In the United States, as elsewhere, the causes of serious crime are hotly debated and many reasons for it suggested. Among these are unemployment, drug-abuse, poverty, ineffective courts, racial discrimination, consumerism, television. Surprisingly, a major study of crime in the U.S. carried out by North-western University found that "the number of poor people in a city is only marginally related to property or violent crime." In other words, American cities with a higher rate of unemployment and poverty do not necessarily also have a higher crime rate.
Many communities across the nation have started their own campaigns against crime, encouraging their citizens to participate in crime-prevention programs and to report crimes. Several civil rights groups actively support such "self-help" campaigns. In some neighborhoods, citizens participate in "neighborhood watch" programs and organize groups to patrol the streets.
