Donald Trump made fighting crime a central focus of his campaign for president, and he cited it again during his January 2017 inaugural address. His administration has since taken steps intended to address crime in American communities, such as instructing federal prosecutors to pursue the strongest possible charges against criminal suspects. Here are five facts about crime in the United States.

1Violent crime in the U.S. has fallen sharply over the past quarter century. The two most commonly cited sources of crime statistics in the U.S. both show a substantial decline in the violent crime rate since it peaked in the early 1990s. One is an annual report by the FBI of serious crimes reported to police in more than 18,500 jurisdictions around the country. The other is a nationally representative annual survey by the Bureau of Justice Statistics, which asks approximately 160,000 Americans ages 12 and older whether they were victims of crime, regardless of whether they reported those crimes to the police.

Using the FBI numbers, the violent crime rate fell 51% between 1993 and 2018. Using the BJS data, the rate fell 71% during that span. The long-term decline in violent crime hasn’t been uninterrupted, though. The FBI, for instance, reported increases in the violent crime rate between 2004 and 2006 and again between 2014 and 2016. Violent crime includes offenses such as rape, robbery and assault.

2Property crime has declined significantly over the long term. Like the violent crime rate, the U.S. property crime rate today is far below its peak level. FBI data shows that the rate fell by 54% between 1993 and 2018, while BJS reports a decline of 69% during that span. Property crime includes offenses such as burglary, theft and motor vehicle theft, and it is generally far more common than violent crime.

3Public perceptions about crime in the U.S. often don’t align with the data. Opinion surveys regularly find that Americans believe crime is up nationally, even when the data shows it is down. In 18 of 22 Gallup surveys conducted between 1993 and 2018, at least six-in-ten Americans said there was more crime in the U.S. compared with the year before, despite the generally downward trend in national violent and property crime rates during most of that period.

Pew Research Center surveys have found a similar pattern. In a survey in late 2016, for instance, 57% of registered voters said crime in the U.S. had gotten worse since 2008, even though FBI and BJS data shows that violent and property crime rates declined by double-digit percentages during that span.

While perceptions of rising crime at the national level are common, fewer Americans tend to say crime is up when asked about the local level. In all 21 Gallup surveys that have included the question since 1996, no more than about half of Americans have said crime is up in their area compared with the year before.

4There are large geographic variations in crime rates. The BJS statistics don’t allow for specific geographic comparisons, but the FBI data shows big differences from state to state and city to city. In 2018, there were more than 800 violent crimes per 100,000 residents in Alaska and New Mexico. By contrast, Maine, New Hampshire and Vermont had rates below 200 violent crimes per 100,000 residents. And while Chicago has drawn widespread attention for its soaring murder total in recent years, its murder rate in 2018 – about 21 murders and non-negligent manslaughters per 100,000 residents – was less than half of the rates in St. Louis (about 61 per 100,000) and Baltimore (about 51 per 100,000). The FBI notes that various factors might influence a particular area’s crime rate, including its population density and economic conditions.

5Most crimes are not reported to police, and most reported crimes are not solved. In its annual survey, BJS asks victims of crime whether they reported that crime to police. In 2018, only 43% of violent crimes tracked by BJS were reported to police. And in the much more common category of property crime, only about a third (34%) were reported. There are a variety of reasons crime might not be reported, including a feeling that police “would not or could not do anything to help” or that the crime is “a personal issue or too trivial to report,” according to BJS.

Most of the crimes that are reported to police, meanwhile, are not solved, at least based on an FBI measure known as the “clearance rate.” That’s the share of cases each year that are closed, or “cleared,” through the arrest, charging and referral of a suspect for prosecution (or through “exceptional means,” such as the death of a suspect or a victim’s refusal to cooperate with a prosecution). In 2018, police nationwide cleared 46% of violent crimes that were reported to them. For property crimes, the national clearance rate was 18%.
