off-topic: Suicide Paradox

"There are twice as many suicides in the US each year than murders."

I heard this startling stantement at the Freakonomics Radio. So I decided to write this post for two reasons. First, to recommend this podcast: The Suicide Paradox. It's really informative and  depressive  funny .

Freakonomics Radio: The Suicide Paradox.

Second, I woud like to recommend a book that I believe to be a masterpiece in Sociology. "Suicide: a study in Sociology" by Émile Durkheim (1858-1917). If you want to understand what Sociology is about and don't have anything else better to do , than you should read this book.

My favorite quote from this book is this one on suicide rate:
It "[...] express the suicidal tendency with which each society is collectively afflicted.... Every society is predisposed to produce a certain number of voluntary deaths." It sounds even better in Portuguese. "Cada sociedade está predisposta a fornecer um contingente determinado de mortes voluntárias"

in time: Greece sees suicide rates on the rise. Durkheim Would Have Predicted That One (by The Global Sociology Blog).

  1. Meet The Economic Complexity Observatory - a multidisciplinary effort between the Macro Connections group at the MIT Media Lab and the Center for International Development at Harvard University.

  2. Are you looking for short term courses or seminars? The Lincoln Institute has just published its annual program for the new academic year 2011-2012.

  3. Excellent piece by Ryan Avent in the NYTimes:One Path to Better Jobs: More Density in Cities (via MR)

  4. All the papers published since 1997 at the Journal of Public Transportation are now available on line (I'm not sure but almost all articles are written in Portuguese). This journal is promoted by the ANTP - National Public Transportation Association (an NGO in Brazil).

  5. The 'flight to the suburbs' debate in the US: Stephen Von Worley did a very good job to map the change in population density from 2000 to 2010 (census tract level) - Growth Rings 1 and 2.

Demographic trends in Brazil

Fabio Giambiagi presents (here) what are the main demographic trends in Brazil over the next few decades. Good news: here is no need to panic.... at least not now. (this post was gently stolen from Leonardo Monasterio)

By the way, I would like to share this excellent chart.

Population Density Maps

Population density is a basic measure in almost every field - from economy to ecology, biology, urban planning, sociology and, of course, demography! Specialists in Visual Communication are changing the traditional ways to visualize population density.

National Geographic came up recently with this awkward map that combines population densities and average annual gross national income per capita. (via Nathan Yau)

I must confess I prefer these density maps designed by Joe Lertola.

Quote of the day

“The city everyone wants to live in would be clean and safe, possess efficient public services, support a dynamic economy, provide cultural stimulation, and help heal society’s divisions of race and ethnicity and class. These are not the cities we live in…Something has gone wrong, radically wrong, in our conception of what a city itself should be.”

(Google attributes this quote to ao Richard Sennett*).

*I couldn't confirm the source. The quote is great anyway.

Seven drivers to population growth in US

[Image Credit: The Texas Tribune obs. shame on me.... I couldn't find a map of population growth rate by county]

Seven drivers to population growth in US counties*:
  1. Higher incomes
  2. January temperature
  3. Proximity to ports
  4. Higher density level (not too high)
  5. Education level
  6. Low manufacturing employment
  7. Limits to housing supply

*source: This is a brief overview of major trends in population growth at the county level written by Glaeser). And here he is talking about Gibrat’s law  "which posits that there is no correlation between initial population and percentage growth in population".

All these trends make me remember Prof. Daniel J. Hogan. He used to stress the growing importance of migration as the main driver of population growth in low fertility contexts. But this shall be subject to a future post.

Differences in life expectancy by education and occupation ! Updated!

If you are interested, as I am, in skilled labor force projections, then you know the role that educational differentials play in life expectancy.
