Right now it's only the population that lives within the census tracts. Another time I'll take into account the physical area of the tracts.

Thanks again for posting these, great data. Do you have San Francisco and Oakland?

This doesn’t work unless you break it down by sq. miles. Percentages of people in census tracts using arbitrary political boundaries with some cities over 300 sq. miles and other cities only 40 sq. miles is useless. You need to use metro areas if you’re going by census tract with comparable area size.

There's a reason why I haven't added it to its own thread yet. And I don't think that square miles by itself will work either, just like population by itself won't work fully. However, either of them are much better than posting a total for an entire city. It starts to give more insight. I never once claimed that it's the end all be all of any of this. It'll take awhile and other measurements before an even clearer picture comes into focus, but this measurement is still a bit more focused than one number for an entire city.

And as I have posted in here at least twice before, I plan on doing physical area constraints. I also think that block group instead of tract is better as well.

San Francisco finished at 41, or about 4.6/100k. Half of these were in the Tenderloin or Hunter's Point. Western half of the city had 0. The needles and poop areas of SoMA had just 1, though I've seen plenty of cars with broken glass in that area.

Oakland finished at 70, 14.3/100k. Downtown had 3, and the nicer areas north of downtown - Temescal, Rockridge, Piedmont Avenue had 0.

Gotcha, either way it's still an interesting insight and I'm glad you put the effort into showing us!

Final stats for LA for 2019:

253 homicides.

At least 12 were officers shooting suspects, so a total of 241 non-officer involved homicides.

2019 Rate- 6.0/100,000, the lowest rate since 1966.

In 2018 there were 259 homicides, but 16 of those were officer involved shootings, so the 241 non-officer involved homicides in 2019 was only 2 less than the 243 in 2018.

Of note, 42 victims were homeless, and officers say virtually all of the perps in those cases were homeless too.

I actually prefer the census tract method in many ways. It breaks down a city based on density and where people live a bit more than just per square mile. Census tracts can vary of course, but generally they have on average 4,000 people. They may be small or large, but if you want to look at what's happening in similarly sized areas based on population it's a good tool.

Gives you a sense of how many people are being murdered based on little pockets and areas of a city.

I'm not surprised Chicago has roughly 2/3 of the city living in tracts with no murders. When you look at a map it seems much more widespread than if you look at where the really high density of actual population is vs just a few murders over that widwspread area.
