Many responses to this misunderstand it. A lot of commenters, in their confusion or ignorance, assume that it must necessarily simply be due to abject poverty and lack of access to other food.

In reality, this is an old cultural tradition that persists from West Africa.
Geophagy – the scientific term of the eating of dirt, earth and mud – has been common in many places in Africa, for a variety of purported purposes.

John Hunter (1973) discusses this, and also how the practice diffused to the United States by the African diaspora.Image
A 1942 survey in a mostly black Mississippi county, showed that at least 25% of school children habitually ate earth.

The reasons given: “earth is good for you”; “it helps pregnant women”; “it tastes good”; “it is sour like a lemon”, “it tastes better if smoked”, etc. Image

Why poverty is not a major cause of violent crime: macroeconomic evidence

While it is well known that poverty tends to be correlated with violent crime, causally informative evidence usually tells a different story. One important source of evidence is the macroeconomic kind.

If economic factors causally affected violent crime, then, when macroeconomic conditions change within a country or region, you should expect violent crime rates to follow. Economic downfalls should lead to increases in violent crime, and vice versa.

One illustrative example is that the homicide rate actually fell in America during the Great Depression–the opposite of what the causal hypothesis would expect.
But it's not just the Great Depression. In the Handbook of Crime Correlates, Lee et al. review the macroeconomic evidence and find that economic downturns have no systematic effect on violent crime.

More recently, Ludwig & Schnepel (2024) also reviewed macro evidence and also concluded that there is no systematic effect on violent crime.
The COVID economic crisis is yet another example. Hoeboer et al. (2024) reviewed the evidence and found that globally there was no increase in violent crime. If anything, it was in the opposite direction.

The United States famously did experience a homicide rate increase starting in 2020. But a careful analysis of the timing of that homicide increase shows that this was the result of a homicide spike immediately following the death of George Floyd. It should not be considered an economic effect.

Overall, there is no clear indication that macroeconomic downturns result in an increase in violent crime. Often the evidence finds the opposite. This is yet another strong line of evidence against the idea that poverty has a major causal impact on violent crime.Image

There is also evidence from within-individual studies:

Further evidence from sibling studies:

The moment when the West changed forever, on its trajectory towards the modern world. Image
This is at least what I have argued. This chart is based on my analysis of a database of notable people. But, if you think such a database is too biased to consider, fear not, for much other evidence points to this being an important transition period.
Abacus schools were important in Italy, emphasizing practical math for the merchant class. These eventually diffused and became popular in Germany and elsewhere.

Furthermore, universities were being set up in large numbers across Europe.

Immigration and crime in Sweden

Recently, I wrote a piece in which analyzed the topic of immigration and crime in Sweden. I have posted some of the findings individually, but I thought it would be useful to compile all the major findings in one place. So, thread below.
Immigrants and second-generation immigrants have higher crime rates than people with Swedish background.

As shown in the image, this is true after adjusting for age and sex compositions, and it's true for all major categories of crime. Image
Between 2015 and 2018, people with foreign background (1st and 2nd generation immigrants) accounted for half of all crime suspects -- a much higher share than their population share.

The overrepresentation was especially prominent for deadly violence and robbery. Image

This chart is wrong.

It might be comparing gun homicides to gun deaths, or something to that effect. Whatever the case, the data is clearly nonsense.

That's unfortunate, because there is a legitimate point to be made.

Short thread.
Cursory research shows that the firearm homicide rate in West Europe is far lower than portrayed in that figure. A firearm homicide rate of ~0.1 per 100k is common. Even in Sweden, known for having serious issues with gun killings, has a rate of ~0.5 per 100k. Image
That said, the demographic point has some merit.

I have personally analyzed the data and found that roughly two thirds of the homicide gap between the United States and West Europe disappears when you compare only native-born (non-Hispanic) white people. Image

I have written a short piece about Sweden's unwillingness to publish information about immigration.

The Swedish government publish very little information regarding immigration and crime or financial impacts. When compared to, say, Denmark, the contrast is glaring. Image
Beyond that, certain data is considered "sensitive" in Sweden. This includes, e.g., nation of birth data.

Note, it's not sensitive in the usual sense of personally identifiable information, but instead in the sense that it's *politically* sensitive.
Because it is "sensitive", ethics boards may explicitly prevent data from being presented by country-of-origin. Image
