I ran a check with Google using "define: segregation" and the definition included, "the act of setting". The title uses the term segregation perhaps innocently but incorrectly. People live where they choose. If the government said they had to live somewhere then it would be segregation. So it's really a map of where people tend to settle. HN should not have allowed the title to stand as is. Perhaps HN feels it's necessary to engage in sensationalism like some of the other similar sites I never or rarely go to any more for technical news.

I watched once a lecture on Coursera about Schelling's model of segregation, which I found extremely insightful. If you see maps like that with strong segregation, one of the first attempts to explain it is "racism". However, if you divide your neighborhood in 9 blocks such that you are in the center, you have 8 neighbors. Schelling's model now shows that even in cities where most people say:"I'd like to live next to…

Any chance you have a direct link to the lecture without having to register for a course?

That's hilarious, I was wondering if my hometown (ATL) would be broken down, and it's the second one. When I moved back there after college I wanted to do some sort of study of the racial segregation in that city. It's totally along that east-west axis, more precisely at Ponce De Leon Ave. All these upper-class streets that run through the nicest neighborhoods in north Atlanta even change their names as they cross ov…

Road name changes often happen at city/county lines where the roads actually changed ownership or used to be separate and ended up joined at some point. Not knowing the history or breakdown of the Atlanta area well, would this make sense there?

Is segregation really the appropriate word here? Separation of the races is coded into our genes and happens naturally without any malicious intent too. It's not much different from the fact that all of us prefer to surround ourselves with people who are similar to ourselves, usually in terms of thinking, hobbies, and interests. Physical attributes influence us as well, whether it's bikers and leather jackets or punk…

Can you point to sources that answer any of these questions:

* What mechanism does this racial separation take?

* What sort of evidence shows that skin color or other ethnic identifiers in genetics are the thing that causes tribal separation vs them just serving as a simple proxy to more complicated factors?

* What explanations of exigent factors are there... for example why are there black and hispanic republicans, or white members of traditionally "black gangs". How do these less common (but not rare) group membership issues override the claimed genetic selection?

* What genetic factors explain the fracturing of groups within groups of seemingly genetically similar (at least on a racial/ethinc level) people?

The claim made here doesn't actually answer any of those questions - I'm not sure the validity of "separation of races is coded in our genes" makes sense given the scenarios highlighted in my questions.

Making race maps in Europe would get you shot, your family hanged and all your friends deemed social outcasts forever. For example: the Swedish crime prevention board (BRÅ) no longer publish crime statistics containing ethnic background information. They stopped a few years ago (2006) when the PC media found out that africans and arabs were way, way over-represented in all crime categories. This is due to political c…

> They stopped a few years ago (2006) when the PC media found out that africans and arabs were way, way over-represented in all crime categories. I would love to see a reference verifying the causality that you are implying when it comes to the decision to drop ethnicity from the statistics. Also, I sincerely doubt that those of African and Arab ethnicity are over-represented in all crime categories. Violence, petty…

Also, I sincerely doubt that those of African and Arab ethnicity are over-represented in all crime categories...tax fraud.

Oops, statistics are secret. Doh!

I feel like you would get a similar result if you did a map of Paris or other big european cities, I'm not sure it's an american thing. I think over here we just don't like/can't compile that kind of racial data. I would be more interested in counter-examples: cities were the melting pot is the rule.

When you control for income and other social factors, it turns out that race is not a risk factor for committing crime.

Reminds me of a similar thing in developmental biology, where if you have two populations of cells, each having a slighly higher affinity for other cells of its own type, then they will very efficiently sort themselves into separate compartments. This is thought to be a pretty important mechanism in the formation and maintenance of structures in the body.

In case anyone's interested, here is a nice (if now rather old, although to be honest scientific writing was so much better back in the '90s) review on the whole business:

http://www.sciencedirect.com/science/article/pii/S0092867400...

In which we find a paragraph describing this process:

"The selector genes do more than specify the pattern and the structures that the compartments will eventually make—they also specify, indirectly, a surface property. This property has been termed cell affinity, meaning that cells that share the same affinity, owing to the same binary code of selector genes, will intermingle during growth. There are a number of different experiments that lead to this conclusion, but perhaps the simplest is the observation that when the selector gene engrailed is removed, in vivo, from a posterior clone of cells in the wing, those cells gain anterior affinity: they now sort out from posterior cells and, if they are in contact with anterior cells, will sort into and mingle with them. Cells from neighboring compartments will have different affinities and tend to minimize their mutual contact, so that where the two compartments abut, there is a relatively straight line across which the cells do not stray."
