1.5 Million Missing Black Men

African-American men have long been more likely to be locked up and more likely to die young, but the scale of the combined toll is nonetheless jarring. It is a measure of the deep disparities that continue to afflict black men — disparities being debated after a recent spate of killings by the police — and the gender gap is itself a further cause of social ills, leaving many communities without enough men to be fathers and husbands.

Incarceration and early deaths are the overwhelming drivers of the gap. Of the 1.5 million missing black men from 25 to 54 — which demographers call the prime-age years — higher imprisonment rates account for almost 600,000. Almost 1 in 12 black men in this age group are behind bars, compared with 1 in 60 nonblack men in the age group, 1 in 200 black women and 1 in 500 nonblack women.

Perhaps the starkest description of the situation is this: More than one out of every six black men who today should be between 25 and 54 years old have disappeared from daily life.

Where do Poles live?

There is no one simple answer to that. Most Poles live in the cities, although the middle class is gradually moving to the suburbs. Most Poles live in the South, in very densely populated regions of Upper Silesia and Lesser Poland, although since 1989 the emerging Warsaw’s financial hub attracts more and more young Poles.

This dot map shows distribution of Poles as recorded on March 31, 2011 - the day of 2011 National Census. One dot depicts 50 people and aggregation level is census tract.

I would like to thank Mr Mirosław Migacz from Główny Urząd Statystyczny (Main Statistics Office) who let me know about this data.

#282: “No one knows how many people live in the country of Bhutan. As of 1975, no census had ever been taken.”

Times have changed.

Seems like about thirty years ago, Bhutan was this crazy remote country that was closed off from the rest of the world, at least according to the book. But times have changed, of course. In 2005, a census was indeed taken in Bhutan. Furthermore, the 2011 estimate for Bhutan’s population is 708,427, making it 165th in the world in terms of population.

Related to the last fact, Bhutan apparently has less people than Alaska does.

Hey there MPOC! I was having a discussion with a friend the other day and was wondering if you or your followers could give me some input, because we're not really qualified to know what the heck we're talking about.We were talking about people of color populations in the UK in medieval times, and about how London probably had tons of races living in it because of how huge it was but someplace like Edinburgh which had a much smaller population and presumably less trade would result in less POC?

I’m a little confused because the way you’ve worded your question, it reads like so: “Bigger cities have more people, and smaller cities have fewer people, right?” Trade doesn’t really come into that.

As for the UK specifically, trade isn’t going to be as relevant because people of color had already been living there since it was part of the Roman Empire. For example, York isn’t especially massive but it’s estimated the population in the 3rd century A.D. was about 20% of African descent. There’s also the fact that the Roman government often sent military personnel into retirement in provinces that they were not originally from, presumably to cut down on trained military forces deciding to take back their homelands and what have you.

So if you consider “medieval times” to begin after the fall of the Roman Empire, you’re actually starting out with a fairly mixed population. If you’re looking at trade being a factor in creating a more racially diverse population, this is something a lot more relevant for medieval Italy. If you’re looking at warfare and occupation being a factor for creating a more diverse population, medieval Spain is going to be more of an example of that. That’s of course in addition to the whole part-of-an-Empire starting population as well.

Classical demography is an inexact science at best, but it does exist. And I am quite sure people won’t stop asking me to somehow make a definitive statement on how many people of color were present in “medieval Europe”, as if there CAN be an answer to such a question! But don’t fall prey to assuming that there is only one factor in thinking about these things-there are many different factors that affect historical populations in any place, at any point during history, just as is the case today.

The study, published November 4 in Science, analyzed the genealogies of settlers in Canada’s Charlevoix Saguenay Lac-Saint-Jean region, northeast of Quebec City. Since the colony’s initiation in 1608, it underwent several waves of geographic expansion. The researchers, led by population geneticist Laurent Excoffier of the University of Montreal, looked at the colony’s marriage and birth records between 1686 and 1960. The analysis found that families living on the edges of the expansions had 20 percent more children than families living at the settlement’s core. They also married one year earlier, on average, and contributed up to four times more genes to the region’s current population.

Unless the world changes the way it deals with vulnerability disasters and climate change, “there’s going to be an increasing number of places where dealing with these disasters is going to be more and more difficult,” van Aalst said in a telephone interview. And in those cases, sometimes the most sensible option, he said, “may be to leave those places.” Such locations are likely to be in poorer countries, he said, but the middle class may be affected in those regions, which aren’t specifically identified in the report. And even in some developed northern regions of the world, such as Canada, Russia and Greenland, cities might need to move because of weather extremes and sea level rise from man-made warming, van Aalst said. In places like van Aalst’s native Netherlands, citizens will have to learn how to handle new weather problems, in this case heat waves.

..so not only that population is rapidly increasing (even while fertility is apparently dropping), but there’s less and less space available for us and the planet is less hospitable..

What are the differences between where same-sex female and same-sex male couples live?

First, Same-sex female couples are more likely than their male counterparts to live in rural areas. Ghaziani thinks that “cultural cues regarding masculinity and femininity play a part.” As one interviewee told sociologist Emily Kazyak:

If you’re a flaming gay queen, they’re like, “Oh, you’re a freak, I’m scared of you.” But if you’re a really butch woman and you’re working at a factory, I think [living in the midwest is] a little easier.

If being “butch” is normative for people living in rural environments, lesbians who perform masculinity might fit in better than gay men who don’t.

Second, non-heterosexual women are about three times as likely as non-heterosexual men to be raising a child under 18. Whatever a person’s sexual orientation, parents are more likely to be looking for good schools, safe neighborhoods, and non-postage stamp-sized apartments.

Finally, there’s evidence that gay men price lesbians out. Gay men are notorious for gentrifying neighborhoods, but data shows that lesbians usually get there first. When non-heterosexual men arrive, they accelerate the gentrification, often making it less possible for non-heterosexual women to afford to stay. Thanks to the gender pay gap, times two, women living with women don’t generally make as much money as men living with men.

Or, they might leave because they don’t want to be around so many men. Ghaziani writes:

Gay men are still men, after all, and they are not exempt from the sexism that saturates our society. In reflecting on her experiences in the gay village of Manchester, England, one lesbian described gay men as “quite intimidating. They’re not very welcoming towards women.”

Population 7 billion

With the worldwide population expected to exceed seven billion in 2011, National Geographic magazine offers a 7-part series examining specific challenges and solutions to the issues we face. The magazine introduces the series with its January cover story “7 Billion,” offering a broad overview of demographic trends that got us to today and will impact us all tomorrow. The first in-depth story will appear in the March issue, focusing on humans’ impact on the planet’s geology. Other stories will follow throughout 2011.
