President Donald Trump has cast a spotlight on crime in several cities across the United States.Washington, D.C., was the first target when, in early August, Trump deployed National Guard troops to crack down on crime. Now, the president has said Baltimore and Chicago are next.“(Washington, D.C.,) serves as a template, and we’re going to do it elsewhere,” Trump said in a Sept. 2 news conference.As Trump centers crime in the national conversation, there are limits to what experts can and cannot say with crime statistics.The FBI publishes some of the most complete statistics, but no database can perfectly capture the nation’s crime. One of the FBI’s crime measurement resources is the National Incidents-Based Reporting System. It contains data on all crimes reported to participating local law enforcement agencies. NIBRS can only provide information on crimes brought to police, but not all crimes that occur are reported. Research shows that sexual assault is often underreported, and cases of petty crime like minor theft may not always be officially brought to the police.The data also depends upon reliable entries from local law enforcement agencies.

Ernesto Lopez, senior research specialist at the nonpartisan Council of Criminal Justice, said that while errors are a concern for researchers, there is no good tool to detect them outside of major discrepancies. He said that while they do occur, they are not necessarily nefarious.“If you’re looking across the nation, I don’t think (data entry errors) have a major effect, in part because there’s a chance the error goes both ways,” Lopez said.The FBI has a second way to measure crime that attempts to adjust for undercounts and data entry issues by sampling 150,000 households across the nation.

WASHINGTON — President Donald Trump has cast a spotlight on crime in several cities across the United States.
Washington, D.C., was the first target when, in early August, Trump deployed National Guard troops to crack down on crime. Now, the president has said Baltimore and Chicago are next.
“(Washington, D.C.,) serves as a template, and we’re going to do it elsewhere,” Trump said in a Sept. 2 .
As Trump centers crime in the national conversation, there are limits to what experts can and cannot say with crime statistics.
The FBI publishes some of the most complete statistics, but no database can perfectly capture the nation’s crime.
One of the FBI’s crime measurement resources is the National Incidents-Based Reporting System. It contains data on all crimes reported to participating local law enforcement agencies.
NIBRS can only provide information on crimes brought to police, but not all crimes that occur are reported. Research shows that sexual assault is often underreported, and cases of petty crime like minor theft may not always be officially brought to the police.
The data also depends upon reliable entries from local law enforcement agencies.

“If you’re looking across the nation, I don’t think (data entry errors) have a major effect, in part because there’s a chance the error goes both ways,” Lopez said.

The crime stats we do know
While there are limitations, the FBI data is what many experts use to analyze the nation's crime issues.
The cities that Trump has pointed to as being riddled with crime and murder — Baltimore, Washington, D.C., and Chicago — are ranked fourth, 10th and 24th, respectively, among cities with the highest rate of murder per 100,000 residents.
In terms of violent crime, they are ranked fifth, 36th and 120th. This is among reporting cities with populations greater than 100,000.

There may be slight variations between the national numbers and what local jurisdictions report. Some of those discrepancies are due to different definitions of homicide and motor vehicle theft.
