Lead Update: White Folks and Alabama Prisoners

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.


It’s been…weeks, at least, since I’ve mentioned lead and crime, and today I got two nice little anecdotes at once. The first is from lead researcher extraordinaire Rick Nevin, who directs our attention to this chart:

As predicted by the lead-crime theory, the prison population of younger cohorts (15-25) has dropped the most. The 26-30 cohort is flat, and the older cohorts are making up a bigger proportion of the total prison population. Why? Because everyone under 30 grew up in a fairly lead-free environment, so they’re less likely to commit serious crimes than similar cohorts in the past. 35-year-olds grew up at the tail end of the lead era, and are still moderately crime prone. Older cohorts were heavily lead poisoned as kids, and they’ve remained more crime prone even as they’ve grown older.

If you have a good memory, you may also recall a post I wrote four years ago explaining that lead poisoning affected blacks and Hispanics more than whites because they were more likely to grow up in dense urban environments with a lot of auto exhaust. Because of this, during the great crime wave of the 60s and 70s, their crime rates went up faster than white crime rates. The flip side of this is that with lead mostly gone, their crime rates are dropping faster than they are for whites. We can see this in the declining share of the jail population made up by blacks and Hispanics. Keith Humphreys shows us the mirror image of this, the rising share of the jail population made up by whites:

The lead hypothesis predicts that young cohorts are less crime prone than older cohorts, so their share of the jail and prison population should decline. It predicts that black crime rates will drop faster than white crime rates. And it also predicts that small-city crime rates will drop faster than big-city crime rates. All of these things have turned out to be true.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
