Probably worth mentioning Foote & Goetz finding of errors in the original Levitt & Donohue paper (though those two have since replied). The impact of lead has also been much discussed as a possible factor.

Kevin Drum has been publicizing research that suggests that reducing the use of lead has caused the reduction in violent crime. His post http://www.motherjones.com/environment/2013/01/lead-crime-link-gasoline has a link to the original paper that claimed the elimination of lead in gasoline was the main factor.

Vladimir & Wonks Anonymous: Thank you for the lit references.

Life expectancy

Hi Livio,

remember your December 2013 thread (now closed) of OECD health data ?

And that a lot of the observed variation could be explained by “eastern Europe” and health care coverage in US, Mexico,. …

The problem is, the factors are brutally high.

After some discussion over this weekend, originally related to other things, like what goes nowadays as a bachelor thesis here and there, ….

The intuition is, that at least half of these five year difference for eastern europe and 15 for health care coverage, should be an accounting fake/misinterpretation of the mortality tables used, AND, that

Life expectancy dependence on income, SES, whatever you name it, should be significantly different between Canada and the US,

And a wonderful real world important topic for your group, to explore in more detail, with proper access to, and understanding of Canadian and US data

Didn't Canada prohibit leaded gasoline in the early 1990s? Lead has been used to explain crime rates in the US, so this might be worth considering.

You can't equate Canada's position on abortion with Roe v. Wade. The 1969 reforms instituted a "Therapeutic Abortion Committee" at hospitals which provided abotions (which were few and far between). Abortion was technically legal but still very hard to get in Canada. It was the various iterations of R v. Mortentaler in Quebec and Ontario in the 1970's and 1980's which really made abortion available in practice.

The "Therapeutic Abortion Committee" system, which was a large barrier to access, was not struck downuntil 1988.

Lead is a neurotoxin that affects behavior. Childhood lead exposure from gasoline and paint correlates well with crime. The Mother Jones stuff by Kevin Drum is great.

This is a worldwide phenomena. 20 years after the lead goes away the crime goes down.

at first I thought, yeah, yeah, yeah, just some coincidence of factors in the US.

But then looking at the Nevin 2007 paper via the mother jones link,

with the data for several european countries .......

still leaves the possibility open, that since the lead is mainly coming from car traffic
"National trends in average blood lead and the use of lead in gasoline were highly
correlated, with median R2 of 0.94"), which represents the rising wealth in countries, just shifting by a few years from country to country, representing social changes (especially increased mobility resulting in less local social control) and not chemcial intoxication.

and none of the international data show any indication of a peak.
It could be there, but there are no data.

AYnd that makes this correlation a mere co-incidence. Sorry

These data are NOT proof of the thesis.
