This is a nice talk by Nicholas Christakis on Sociology and Social Networks. It is very concise and well presented covering a quite broad range of topics such as suicide, social capital, collective behavior and social networks.
What attracted my attention though was the part on the Social Network Effect Behind Obesity, where Christakis talks about this paper he and James H. Fowler have published in The New England Journal of Medicine (in the video, skip to 19:06). Quite impressive!

A couple of cities such as São Paulo, Bogota and Mexico City have already tried to cut down on traffic using licence plate schemes. Needless to say they have achieved limited success
if any .
In this Freakonomics episode Dubner and Levitt talk about the universal law of 'unintended consequence' and how it applies to such schemes.

Here is a presentation by Hans Rosling (aka the “Mick Jagger” of TED) breaking down the myth of demographic divide between rich and poor countries.

No wonder why we never get tired of watching.

The issue of World Population Bomb is gradually losing ground to other issues such as imploding national populations and aging workforce.
Of course we always find those who sounds extremely pessimistic. Jim Russell (Burgh Diaspora blog), for example, points out to several declining places (low fertility and no migration attraction). According to him, Southern New England Is Dying, Puerto Rico Is Dying, China Is Dying, Germany Is Dying, America Is Dying, Sun Belt Counties Dying, Silicon Valley Is Dying, New York City Is Dying, London Is Dying, San Francisco Is Dying etc etc
ok. We understood, we're all dying anyway
The McKinsey Global Institute has published a report on how aging populations will reduce global savings (15min audio summary). Other pessimist, Jonathan Last (author of 'What To Expect When No One's Expecting'), trumpets a coming demographic disaster:
"Forget the debt ceiling. Forget the fiscal cliff, the sequestration cliff and the entitlement cliff. Those are all just symptoms. What America really faces is a demographic cliff: The root cause of most of our problems is our declining fertility rate."
The fact is no one is actually optimistic about current demographic trends. Nancy Folbre (MIT) has a more moderate opinion, although still far from being optimistic.

The Marginal Revolution blog led me to Jon Millward's page. Jon Millward is a sort of 'Ideas Detective', in his own words. Every now and then he comes up with a probing analysis of something 'new', like the last words of death row prisoners or call girl reviews.
His latest study makes a deep analysis of Porn star demographics. This is probably the largest study of porn stars ever undertaken, including age, race, hair color, birthplaces, film categories etc. It’s based on a massive data set of 10,000 porn stars extracted from the Internet Adult Film Database.

paper: Spatial Equilibrium in Cities: the Isobenefit Lines
... many cities, particularly in Europe, are much more complex than this [monocentric urban model]. And in recent years, city planners have begun to place more emphasis on developing additional centers within cities. So it’s increasingly common for a city to have several centers performing different functions.
D’Acci’s new model is designed to cope with this increased complexity. His idea is to calculate the benefit of a given location to a resident, taking into account the effect of all the city’s various amenities.Having done that, he calculates locations of equal benefit, connecting them with so-called “isobenefit lines”.

Prof Henry Overman (SERC / LSE) gave a very interesting lecture a couple of weeks ago. The lecture was titled 'The Economic Future of British Cities: What should Urban Policy Do?'
He addressed several issues such as migration, housing, skilled workforce, labor productivity and regional wage disparities, to name a few.
You can download both the lecture and the slides here. You may also go further into Overman's writings on SERC blog - Part I, Part II.
