Decline in homicides in Detroit!

FRIDAY, JANUARY 5, 2024

A failure to adjust: A front-page report in the New York Times carried some welcome news.

The report appeared on Saturday morning, December 30. It reported a sharp decline in murders during this past year.

Arango and Robertson did the reporting. Headline included, their report started like this:

After Rising During Pandemic, Murders Fell Sharply in 2023

Detroit is on track to record the fewest murders since the 1960s. In Philadelphia, where there were more murders in 2021 than in any year on record, the number of homicides this year has fallen more than 20 percent from last year. And in Los Angeles, the number of shooting victims this year is down more than 200 from two years ago.

The decrease in gun violence in 2023 has been a welcome trend for communities around the country, though even as the number of homicides and the number of shootings have fallen nationwide, they remain higher than on the eve of the pandemic.

In 2020, as the pandemic took hold and protests convulsed the nation after the murder of George Floyd by a police officer in Minneapolis, the United States saw the largest increase in murders ever recorded. Now, as 2023 comes to a close, the country is likely to see one of the largest—if not the largest—yearly declines in homicides, according to recent F.B.I. data and statistics collected by independent criminologists and researchers.

The rapid decline in homicides isn’t the only story. Among nine violent and property crime categories tracked by the F.B.I., the only figure that is up over the first three quarters of this year is motor vehicle theft...

According to FBI data and other statistics, homicides were substantially down last year, as compared to the number recorded in 2022. 

Arango and Robertson included several points of caution about these preliminary figures. Our only interest today concerns the way they described the situation in Detroit.

Homicides were down in many cities last year, as the reporters note. That said, they started with that statement about Detroit. Later, they added an effusive wrinkle:

Detroit is on track to record the fewest murders since the 1960s.

[...]

The city of Detroit is on track to record the lowest number of homicides since 1966, a remarkable milestone even given its substantially smaller population today. Local officials credited an aggressive effort to jump-start the criminal justice system, which had largely stalled in the pandemic.

“We know why violent crime soared in America,” said Mayor Mike Duggan at a news conference this month. “The criminal courts shut down. You couldn’t put 12 jurors in a room.”

When it comes to Detroit, that's all they wrote! We decided to fact-check the reporters' claim about that "remarkable milestone," in which they compared the number of homicides in Detroit last year to the number in 1966.

According to Arango and Robertson, Detroit has achieved "a remarkable milestone even given its substantially smaller population today." But how much smaller is that population? We decided to check it out:

Population of Detroit:
1966: 1.6 million (est.)
2023:    620,000 (est.)

It's come down a long way, baby! That said, here are the recorded numbers of homicides in Detroit for those two years:

Homicides in Detroit:
1966: 214
2023: 252

Back then, the city was almost three times as big. It had substantially fewer homicides. 

By our calculations, what follows is the approximate homicide rate for the two years in question:

Approximate homicide rate in Detroit:
1966: 13.4 per 100,000
2023: 40.6 per 100,000

How remarkable does last year's milestone look after that basic statistical adjustment?

What we have in that news report is the latest failure to adjust. Sometimes, reporters fail to adjust for inflation. Sometimes, though, other failures to adjust may find their way into print.

According to CNN, homicides last year were down by 18.4% in Detroit as compared to 2022. That's a sensible type of comparison. It seems to us that the Times reporters should have just left it at that.

  1. Innocent question here: is Detroit basically empty now? Sounds like a cool place to move to, what with its already well set up structure and heritage.

    And yes, the 60- year comparison is meaningless. I suspect that these younger journalists now have no sense of the past, or exactly how much 1966 differed from almost any time afterwards, everywhere.

    1. A problem with moving to a shrunk Detroit is underfunded pensions. Pensions should have been fully funded when the covered employees were working, but in many cities they weren't. Future Detroit residents will have to pay big taxes to pay pensions to the many city employees who were working there when the city was much larger.

      Delete
    2. This idea of fully funding pensions almost never happens anywhere, in businesses or public orgs, without mandating it.

      Delete
    3. It IS mandated. Businesses must obey the mandate, at least formally. They're OK as long as an actuary approves their pension fund amount. No doubt some businesses take advantage by under-funding. A few businesses overfund, because that reduces taxable earning s and defers income tax.

      AFAIK municipalities are also required to fully fund, but cities seem to have the power to ignore this requirement if they want to. And, of course, they can underfund by finding an actuary who approves their level of funding.

      Cities with dramatic drops in population are caught in death spiral. As the population drops, the per person obligation of the remaining population grows. That means higher taxes and worse city services. Those problems encourage more people to move away. If only a single person were left, s/he would be fully responsible for the entire unfunded pension liability.

      Delete
    4. Everyone knows Detroit has had a lot of problems. What’s your point? You can’t generalize from Detroit to other different cities.

      Delete
    5. My point is: Cities with underfunded pensions that experience dramatic drops in population are caught in a financial death spiral.

  2. Most of the lead-poisoning crime wave came after 1960.

    ReplyDelete
    Replies
    1. Cars were invented in the 1920s and lead has been around in paint and other products (water pipes, dishes, toy soldiers for example) for a long time. I think you are wrong about attributing the crime wave to after 1960, when the abatement projects were all after 1960.

      Delete
    2. There was a crime wave in the 1930s from lead paint. The economic boom after WWII brought gas-guzzling cars with leaded fuel. Kids exposed to lead when two or three years old have an elevated risk to be criminals in their teens and adulthood.

    3. This more controversial than Drum acknowledges.

    4. IMO Democrats like to blame various problems on lead because that allows them to avoid acknowledging that some of their policies haven't worked and might have even been counter-productive.

    5. David, lead interferes with brain development. It doesn’t care about policy or politics. It’s like methane and carbon dioxide, which absorb infrared light, regardless of policy, politics, or economics.

      Lead and carbon just don’t care.

  5. Homicides are way down compared to last year and during the pandemic, not down compared to before the pandemic. The 1966 comparison is specious. Why is Somerby even mentioning it? The reporter only brings up 1966 in order to say that the current rate is lower than any year since 1966. Is Somerby suggesting that there are far fewer people in Detroit compared to last year? If so, those are the numbers he should be furnishing to make his case.

    This is a stupid nitpick because homicides are down all over the country (but not compared to pre-covid numbers) and no one is arguing that there is any magic involved. Most of our larger cities have increased in population, not decreased like Detroit (making Detroit an anomaly). If the decline in population were responsible for the homicide decrease compared to last year (not 1966), you wouldn't expect to see such a widespread phenomenon.

    So, if Somerby is not making the argument that this is an artefact of population change, why is he bringing this up at all? It adds nothing but confusion to a straightforward and true report.

    Somerby says: "According to CNN, homicides last year were down by 18.4% in Detroit as compared to 2022. That's a sensible type of comparison. It seems to us that the Times reporters should have just left it at that."

    I think Somerby might have noted his quibble, shrugged and then written about something else that is actually worth people's time to consider. This is just spreading the stupid and Somerby said earlier this morning that he is against stupid.

    1. He bring up 1966 because the reporters did. They used it to underscore what they called "remarkable milestone" and implied the changes since 1966 represented a significant improvement in the city's homicide rates over a long time span. Somberby considers this misleading because of their failure to adjust the population base rate. I can see where you would think it is a nitpick. It's OK to disagree and feel hurt.

      Delete
    2. I think it is stupid to make such a fuss over one offhand true remark that affects nothing about the report. My feelings aren’t hurt — my time has been wasted.

      Delete
    3. You and Somerberry are both making basically the same point.

      It's okay to feel like the decision you made to spend your time reading the essay was a mistake. That's common in natural.

      Delete
    4. (the 1966 comment was not exactly true. The writers committed a base rate fallacy as Summersby accurately pointed out.)

      Delete
    5. The reporter only said murders were the lowest since 1966. That is a fact. I agree that the rate matters but this was said in the context of a comparison with last year, where the general population is closely similar, so Somerby’s complaint is irrelevant.

      Delete
    6. So, you feel the year over year comparison is a more sensible type of comparison and Somerby should just leave it at that. That makes sense.

      Delete
    7. Yes, and I think Somerby manufactured a complaint because he likes to portray reporters as unreliable because it undermines faith in our press, which is a cornerstone of democracy. This is a nothingburger.

      Delete
    8. I'm more interested in reason and rational debate grounded in objective facts, logical reasoning, and evidence rather than subjective speculations on one's personal motivations. Subjective speculations on one's personal motivations repulses rational debaters but it is common for a lot of us to turn to that tactic. So, I understand you feel the way you do in issuing personal conjectures over logical reasoning. Thanks.

      Delete
    9. There is a pattern here of Somerby manufacturing trivial nitpicks in order to portray the press as incompetent. He makes plenty of mistakes himself. None of that is subjective. Somerby’s website is searchable. No, I will not spend any time documenting anything for you.

      Delete
    10. It would have helped if Bob had interpreted 'since' correctly. Of course the aggregate number for 1966 is going to be lower than 2023. The less-unuseful comparison would be to 1967, when there were 281 homicides. Then you can argue over rates un-distracted.

      Delete
    11. It's subjective unless you document it. But I understand how you feel. It's OK to feel frustrated and like someone has hidden, nefarious motivations. Especially if it challenges your deeply held beliefs. There's nothing to be ashamed of deciding to compulsively write and ruminate about these subjective feelings. Although I trust you are seeing a professional to help you come to terms with it. Mental health is complex and unique to each individual. Thanks for sharing.

    12. American's trust in media has fallen to a historic low. Maybe it's because a random blogger accurately nitpicks their mistakes in order to make them seem incompetent.

      Or maybe it is something else.

      Delete
    13. It is documented. All of Somerby’s essays are part of his archive so anyone can read them. I’ve already explained what he did today, which is not subjective but obvious, especially to anyone trained in statistics. A little bit of knowledge, like Somerby’s affection for calculating baserates, leads him to think this reporter made an error when the actual comparison is to 2022, not 1966. The mention of 1966 distracts Somerby so that he ignores the larger meaning of what is being said.

      Your patronizing psychobabble is annoying but you don’t seem to have any real expertise about statistics or psychology. No one was saying the murder rate was better than in 1966. Somerby often goes off on these meaningless tangents because (1) he ignores context, (2) he loses track of the main point, (3) he is motivated to find fault, (4) he thinks a trivial gotcha invalidates everything else said, (5) his knowledge of stats is superficial.

      You sound like a freshman psych major applying the contents of you Psych 101 textbook to everyone you meet. You sound silly doing that.

    14. @11:21. What Somerby does can’t be helping. It supplements the full-scale attack by the right. The press isn’t perfect but disinformation and propaganda are worse. We need to defend truth.

    15. 11:30 Thank you for your constructive criticism and for providing more theories about his motivations and additional unique interpretations of this essay. You are important and deserve your say. Many people still defend and support the media even as it evolves into an anachronism in the age of the digital revolution and diversified information channels. Many people don't even realize the media is becoming an anachronism before our very eyes. Some, very, very few, but some still even trust it. It's an interesting topic that Somerby has thankfully documented for people in the future to review. I appreciate your statistical and psychological expertise and imaginative theories.

    17. "The press isn’t perfect but disinformation and propaganda are worse. We need to defend truth."

      As we all know, Biden has been found guilty by 2 federal courts of acts of “coerced censorship” and has been found to have “coerced or significantly encouraged social media platforms to moderate content” in violation of the First Amendment. The full-scale attack by the right seems worse though . Biden “coerced the platforms to make their moderation decisions by way of intimidating messages and threats of adverse consequences” and “significantly encouraged the platforms’ decisions by commandeering their decision-making processes” but those are old crimes. Trump is more important. Trump is a threat to democracy. If he is reelected he will become a dictator and begin a campaign of assassinating petty criminals (according to a major mainstream journalist). This is more important. We need to support the Biden administration's defense of democracy through censorship, trying to throw their political opposition into jail, and attempts to remove any other people from the ballot. How can Democracy survive the full-scale attack by the right without these patriotic moves by Biden?

      “Zeke” is someone they will hear out. Rightly so.

      Dr. Emanuel and others are alarmed about the rhetoric in campus protests, and Emanuel want changes made to the entire educational process.

      Gay had been coached to say as little as possible during her appearance in congress. She mouthed no sentiments toward their goal. She came off as incoherent and as flaky as some of the protesters. That was not what concerned parents and donors wished to hear.

      I thought Gay would manage to survive this brouhaha that is going on within academia and the WH (we’ve even seen it here amongst anonymices) She did not.

      Rufo was only a means.
