On Twitter, a reader notes that black homicides tend to be more seasonal than white homicides:

This more or less checks out: blacks died by homicide according to the CDC death certificate database about 22% more in June to August over the years 1999-2020 than in December to February.

For whites, the seasonal gap was only 7%; for Hispanics 18%.

The gap between July-September versus January-March is 27% for blacks, 16% for whites, and 23% for Hispanics.

But all September figures are inflated by 9/11 in 2001.

For whites, about 20% of all homicide victims in September over that 22 year span died in the terrorist attacks on 9/11.

My impression from local news coverage is that a lot of blacks get murdered at outdoor parties or on the sidewalks outside clubs, so the current temperature matters more.
