Data suggests number of murders reported in America rose by 4.3 percent since 2020, with vast majority of homicides committed using some type of firearm even as the tally excludes nation's two largest cities, New York and Los Angeles.

About 9,700 law enforcement agencies were not able to supply full data sets by the March 2022 deadline for Wednesday's report.

The number of murders reported in the United States rose last year, the federal investigation agency has said, but it warned that a change in its data collection methods meant that its tally excluded the nation's two largest cities, New York and Los Angeles.

The FBI said on Wednesday its data suggested the number of murders reported in the United States rose by 4.3 percent since 2020, with the vast majority of those homicides committed using some type of firearm.

The increase follows a 29.4 percent surge in the murder rate the year before.

Although the new report shows that overall violent crime decreased by about 1 percent in 2021 and the statistics are still incomplete, experts said the bureau's findings show that violent crime remains a significant problem in America.

"Violent crime, and specifically gun crime, continues to be a huge challenge for our nation," former Houston Police Chief Art Acevedo told reporters on a call organised by the left-leaning Center for American Progress.

Justice Department officials told journalists on a Tuesday conference call ahead of the full data set's release that the transition to a new method of data collection meant that just 52 percent of US law enforcement agencies had submitted their full 12-month 2021 crime data by the bureau's March 2022 deadline.

The data does not include full reports from agencies including the New York City Police Department, the Los Angeles Police Department, the Los Angeles County Sheriff's Office, the San Francisco Police Department and Arizona's Phoenix Police Department.

Republicans blame Biden administration

The increase, and the incomplete data, have already drawn some criticism as Republicans increasingly focus their campaign messaging on concerns about crime ahead of the November 8 midterm elections, when they are favoured to win back control of at least one chamber of Congress from President Joe Biden's Democrats.

"Violent crime has surged in this country under the Biden administration," Republican US Representative Michael Burgess of Texas said in a statement, adding that the new data is "very concerning."

A Reuters news agency/Ipsos poll published on Wednesday showed that registered voters, including the key demographic group of suburban women, believe Republicans are better suited to addressing crime than Democrats.

This marks the first time the FBI and the Justice Department's Bureau of Justice Statistics have fully transitioned to a more detailed crime-reporting system, known as the National Incident-Based Reporting System.

About 9,700 law enforcement agencies were not able to supply full data sets by the March 2022 deadline for Wednesday's report.

Department officials said they were able to generate state-level estimates for about 40 of the 50 states, which covers about 65 percent of the US population.

Justice Department and FBI officials told reporters on Tuesday that the new methodology for crime data collection will include many new details on crimes that previously went unreported.

These include data for drug offences, human trafficking numbers, bribery, counterfeiting, and more detail on things such as simple assault and intimidation offences.

"Even though it's incomplete data and we cannot draw any conclusions about national trends, we have to respond to the concerns that people have about crime and violence," said Insha Rahman, vice president of advocacy for the Vera Institute.

She added that the report only underscores the need for evidence-based solutions to reduce gun violence and make communities safer.
