Fact-check: Kris Mayes said Arizona’s murder rate rose by 20% under Republican leadership – Cronkite News/Politifact

In the Sept. 28 attorney general debate hosted by Arizona PBS, Democrat Kris Mayes said, “We have seen over the last 10 years, under Republican agencies and Republican governors, a rise in the murder rate in Arizona of 20%.”

The Republican Party has controlled the governorship and both houses of the state Legislature for the last decade. The number of homicides rose during that time, but so did the state’s population. That undercuts Mayes’ statement.

Distinguishing between the number of murders and the murder rate

We reached out to Maye’s press office and it pointed to a fact sheet from the Center for American Progress Action Fund, a Democratic advocacy group.

The document used data collected by the Arizona Department of Public Safety showing the state’s raw number of homicides per year from 2010 to 2020, the most recent year of data collection.

The number of murders increased by 20.62% from 2010 to 2020, state data shows.

In the debate, Mayes referred to the murder rate, which is different from the number of murders. The rate is the frequency of murders per 100,000 people.

Edward Maguire, criminology and criminal justice professor at Arizona State University, said a simple count of homicides is misleading.

“Because during that same period, the population of the state grew,” said Maguire. “The appropriate way to do this analysis of change is to use homicide rates.”

Including 2020, the murder rate in the state increased by about 4.14% over the last decade.

The FBI also tracks homicides and although its yearly numbers differ from the state’s, the trends and patterns in homicides are the same.

The COVID year outlier

The 4.14% increase in murder rates between 2010 and 2020 does not tell the whole story.

As the COVID-19 pandemic spread, homicides in Arizona, and the United States, skyrocketed in 2020.

Criminologists advise caution when including 2020 in an analysis of murder rates.

“In 2020, violence was disrupted by a massive environmental change that impacted culture, routine activities, levels of anxiety, employment, etc,” said Charles Katz, a criminology professor and director of the Center for Violence Prevention and Community Safety at Arizona State University.

The exact reasons for the increase in murders in 2020 are still being studied, Katz said.

Excluding 2020 from the decadelong analysis makes a difference.

From 2010 to 2019, homicide rates in Arizona decreased by about 20.58%.

The data also shows that homicide rates fluctuated throughout the decade.

Rates fell slightly from 2012 to 2015, then increased from 2016 to 2017, and fell from 2017 to 2019. The murder rate then crept upward in 2019.

“These kinds of fluctuations are typically a consequence of broader environmental and macro level changes,” said Katz. “These changes are modest and it would be tough to assess the causes.”

Our ruling

Mayes said, “We have seen over the last 10 years under Republican agencies and Republican governors a rise in the murder rate in Arizona of 20%.”

Mayes’ number is incorrect. The number of murders in the state increased by 20% from 2010 to 2020, but the murder rate rose by 4%.

That span includes the first year of the COVID-19 pandemic, which disrupted many norms, including homicide patterns. Excluding that year, the murder rate fell by about 20%

We rate this claim Mostly False.

  1. Bottom line, most Arizonians will grab onto the Kris Mayes quote and never question it. Only people who follow politics will question comments from the “other” party. Over time, we have seen the protective cloak fall over Democrats comments as truthful. With main stream media all of the same culture, public opinion has been altered to support a destructive culture in America. Without an honest journalism structure in our media the watchful eye on politics is lost or at least compromised.
    The heavy lifting must be done by strong alternative media allowing people to “think” and wonder which communications should be believed. Our government schools are being damaged by not encouraging critical thinking at every level of learning. Educating on what to think and believe is replacing true facts and critical thinking skills in our public schools and even more so in colleges and universities. Wake up people and vote for change and watch how they perform after being elected.

  2. Whatever Radical Leftists like Kris Mayes says, we know the exact opposite it true.

    If they say “murder went up under the Republicans”, that means murder went down under the Republicans.

    If they say “the 2020 election was the most secure in US History”, that means the 2020 elections were the LEAST SECURE in US History and the Radical Left successfully stole multiple elections.

    Zero credibility!
