The 1 % of the population accountable for 63 % of all violent crime convictions!
Results:
A total of 93,642 individuals (3.9 %) had at least one violent conviction. The distribution of convictions was highly skewed; 24,342 persistent violent offenders (1.0 % of the total population) accounted for 63.2 % of all convictions.
Persistence in violence was associated with male sex (OR 2.5), personality disorder (OR 2.3), violent crime conviction before age 19 (OR 2.0), drug-related offenses (OR 1.9), nonviolent criminality (OR 1.9), substance use disorder (OR 1.9), and major mental disorder (OR 1.3).
Conclusions:
The majority of violent crimes are perpetrated by a small number of persistent violent offenders, typically males, characterized by early onset of violent criminality, substance abuse, personality disorders, and nonviolent criminality.

Ack! That was in Sweden, too...the article you linked to.
I was seat-of-pants estimating the percent of black males as described below. and got this data from:
Federal Bureau of Investigation Crime Data Explorer<.b>
Blacks are 12% of the population, males are roughly half that, so six percent, and I read 40% of black males have a felony conviction, so I just round it to say, 3% with some portion of that being violent crime, let's say half of that, so that makes it 1.5% of the US population responsible for 36% of all violent crime between 2010 and 2020. (All blacks, male and female account for 45% overall, and on the same website, violent crime broken down by sex shows women are responsible for 20%, so I multiplied .8 x 45% to get the 35%.
Here is the graph not broken down by sex:
It is a disgrace.
If you had a town of 10,000 people experiencing a high level of violent crimes, and you could narrow it down to 150 men causing more than a third of it, you would expect a crackdown to put those 150 men behind bars or run them out of town.
