Polycentric project for Moscow

The City Hall of Moscow has approved extending the city's borders to the south-west by 2014. According to the plan, the city territory will more than double. It seems they are seriously considering a more polycentric orientation (via Peter Gordon).

It is a curious remedy since Moscow is not highly monocentric when compared to other cities.

Simulations from the Early Days



Michel Batty has gathered some really interesting Early Animations of Urban Models.

One of these videos shows Jack Dangermond (co-founder of Esri) and Allan Schmidt* talking about the 'Harvard Laboratory for Computer Graphics and Spatial Analysis'. (more videos on GIS history here.)




*Allan Schmidt was responsible for what is probably the earliest "movie" of urban expansion. A SYMAP time lapse movie depicting growth of Lansing, MI 1850-1965.

AfriPop Project

AfriPop: demography aims to produce detailed and freely-available population distribution maps for the whole of Africa . It provides "detailed gridded spatial population datasets showing age composition by 5-year groupings and gender." (via devcondata). 

obs. I have just added this project to our Online Databases List, on the right of this page.

Birth rate plummets in Brazil

A good article by The Washington Post on Brazil's Fertility Decline (via Ricardo Ojima)

excerpt: "The country’s fertility rate has fallen from 6.15 children per woman in 1960 to less than 1.9 today. That is a lower rate than in any other Latin American country except Cuba, which has state-sponsored family planning and legalized abortion. It is also lower than the rate for the United States, which at 2 per woman is just enough for the population to replace itself."

When I was a kid, people used to joke saying that some poor families would have more children because they didn't have television at home. Apparently some take this argument fairly seriously !

Visualizing Migration III

Even Westvang did this amazing short animation showing the patterns of 300.000 Norwegians moving house. He did it by cross-referencing 8 million tax records from 2006 and 2007 to track changes in postal codes.

This kind of dataset is rarely available for other countries (via information aesthetics). In Norway it is made public every year!*

*obs. Now you might be thinking "....mmm. I should have used Norway data in my PhD. Dammit"

Why some city streets are more crowded than others

The Economist Magazine has written two interesting articles on 'Crowd Dynamics' over the last two months (here and here). Very informative about the contribution of space syntax to urban planning.
