The FBI has finally released crime statistics for 2023!

Let's have a short thread.

First thing up is recent violent crime trends: Image
Now let's focus in on homicides.

The homicide statistics split by race show the same distribution they have for years. Image
As with every crime, it's still men doing the killing, but it's also largely men doing the dying. Image
What about Hispanics? Their data is still a mess, but here it is if you're interested. Image
The age-crime curve last year looked pretty typical. How about this year?

Same as always. Victims and offenders still have highly similar, relatively young ages. Image
Everything else, from locations to motives to weapons is pretty similar to previous years. What's different is that the OP might show incorrect numbers.

For the past two years, the FBI has silently updated their numbers after about two weeks.

You can use the web archive to see that the data from the OP is the data shown at release last year, and the data from 2023 is the 2022 data with the FBI's suggested reductions (i.e., -11.6% homicides, -2.8% aggravated assaults, -0.3% robberies, etc.).

But you can see on their site now that they've adjusted the numbers up, so the reduction they suggested has brought us down to a figure that's less impressive than my chart shows. The difference isn't huge so I showed the OP without updating to their new data.

For reference, 2022 as reported then had a homicide rate of 6.3/100k, and they silently updated that to 7.48/100k. The 2023 data they provided today actually has a murder rate of 6.61/100k, higher than last year's initially-reported number, but lower than the updated number. To make matters worse, if you use their Expanded Homicides Report, you get a rate of 5.94 for 2022 and 5.24 for 2023.

Methodology matters and we get to see inconsistency in this year's data, not even data that's been updated or anything. It's a mess, so take everything with a grain of salt and, in the interest of caution, only interpret trends. Trends are mostly common between all data sources even if the absolute magnitudes are off, constantly updated, etc.

Because America has made the wise decision to compensate blood donors, it has ended up supplying some 70% of the world's blood plasma.

This is one of America's top exports, and each year, America saves hundreds of thousands of lives because it does this. Image
Some people argue against plasma donation on the basis of it being disproportionately used by poorer people

They say it's exploitative: they feel that selling something your body makes is wrong if disparate in ways they care about

But it's a lifesaver!

There's also research indicating that plasma donation can be healthy!

(And there's more indicating that, with compensation, it might reduce crime in the local area.)

It's Pride Month, so let's talk about why San Francisco is so incredibly gay.

Military policy.

🧵 Image
In 1982, Randy Shilts published his biography of Harvey Milk, entitled "The Mayor of Castro Street".

For those who don't know, Harvey Milk was the first open homosexual to be voted into public office in the state of California.

He was on the San Francisco Board of Supervisors. Image
The biography contains a fair bit of background, not just about Harvey Milk, but about San Francisco's gay community more generally.

In its early years, San Francisco attracted large waves of mainly male migrants motivated by the promise of gold in California. Image

My Uber driver says

- His license is suspended
- He was once a soldier for a Mafia family
- He's telling me about his time in Rikers
- He's showing me YouTube videos
- He's telling me his theories about Jews
He's telling me about gang wars he was in ad a kid.

He's wondering why all the Chinese girls are lined up - for an audition?

He says to go to Mother's Ruin for latin prostitutes.

All of this entirely unprompted.
"Yeah, these African guys, yeesh"

"I couldn't fuck that whore because I got the erectile dysfunction."

He just keeps going.

This is just not true and it's sad that people believe it.

It's also indicting, when it's so obviously false if you just look out into the world. What you see should match what the statistics clearly show:

Estimated marriage effects for men and women are almost always similar🧵 Image
In that chart, I used the GSS and found something many people replicate:

1. Cross-sectionally, there's a relationship between being married and life satisfaction. It's similar for men and women.

2. Within persons—causally!—marriage boosts life satisfaction, but more for women.
Leveraging the same within-person design, we can use the Add Health dataset to look at stress and depression.

For both sexes, the effects are indistinguishable.

But they're also mostly not real: it's just that people who get married tend to be less stressed and depressed! Image

As a recap on my appearance, Eli Lilly is pursuing:

- A one-dose drug for preventing most heart disease
- A vaccine for chlamydia
- A vaccine for gonorrhea
- A vaccine for Epstein-Barr
- A drug that lets you stay awake longer and feel more rested

It's a golden age of pharma! Image
And remember, Eli Lilly's big break historically was the University of Toronto licensing them to produce insulin.

They started off by giving it out for free, saving the world's diabetics at a time when there was no treatment available.

They've always been a force for good. Image
I think

- The heart disease drug will succeed
-- Will it commercialize? It can, easily. But I'm 50/50 due to the competition
- Chlamydia and gonorrhea vax will succeed, but I don't see much commercial potential with Lilly
- EBV vaccine will fail with Lilly, succeed eventually

Eli Lilly has done it.

They've gone and made what seems to be a powerful, permanent gene therapy for LDL cholesterol.

That means they'll be able to effectively prevent most heart disease with a single infusion! Image
Almost all of the side effects were just things you see with any infusion. Some people react poorly to needles and having to sit for a while🤷‍♀️

And that's what we expect, because the people with good PCSK9 genes naturally are totally fine. This therapy catches the rest of us up!
This is amazing stuff, beating drug administration because it's permanent, and it only gets better from here.

We are going to get so healthy, so fast. Our grandkids are going to hear about heart attacks and have never actually seen one.
