Cities' Areas of Influence in Brazil

Since 1966, the Brazilian Institute of Geography and Statistics (IBGE) has been carrying on a research on the Brazilian network of cities. The project is called REGIC - Regiões de Influência de Cidades (which I would poorly translate as " Cities' Areas of Influence ").

They have recently made available the vector files (shape files) of the latest edition of the research (2007).

The methodology used in this research has changed a lot from its first edition in 1966. The latest 2007 edition, however, is pretty much excellent. The authors address the Brazilian network and hierarchy of cities based on a massive data set. It incorporates all sort of spatial connections such as:

• Federal public administration
• Business management
• Passengers transport (flight and Road connections)
• Bank branches
• Education institutions
• Health services
• Density of Internet domains
• Television networks and even Destination of agricultural production (I bet I have forgotten something)

shameless self promotion moment: The Institute for Applied Economic Research (IPEA) has recently organized a book that provides some good insights on this issue. The book is entitled "Urban-Regional Dynamics - Urban Network and its Interfaces" (my poor translation again).

Quote of the day

"Cities are the crucible of human civilization, the drivers towards potential disaster, and the source of the solution to humanity's problems. It is therefore crucial that we understand their dynamics, growth and evolution in a scientifically predictable, quantitative way. The difference between 'policy as usual' and policy led by a new quantitative understanding of cities may well be the choice between creating a “planet of slums” or finally achieving a sustainable, creative, prosperous, urbanized world expressing the best of the human spirit."

by Luis Bettencourt & Geoffrey West

ps. Keep that in mind. But, remember not to take it as a mantra.

Where refugees come from (and go to)

The latest statistics by UNHCR (UN's High Commission for Refugees) are out. You can download the data here and check the Guardian's article on this topic here.

and don't forget the interactive map by Simon Rogers - via The Global Sociology Blog

Copy & Paste Cities

China is getting famous for its empty cities.* Well, China also has its Copied Cities now!! Geoff Manaugh (from BLDGBLOG) wrote an interesting article on this a few days ago (via MR and Urban Planning Blog - thanks Leo Monasterio for the tip).

Interesting Demography Bolgs

Just in case you didn't notice them on the blogroll, there are two interesting demography blogs you should read (leave a comment if you know another one).

There is the Changing Demography blog (by Kenneth W. Gronbach), which is more focused on market demographics. They have an excellent post on The Mysterious Labor Shortage in China.

And there is also the excellent Demography Matters blog (by a group of demographers and other social scientists). They have a lot of good posts to which I often link here.

ps. you might find some usefull Online Databases on the blogroll too.

Seminars on Population Studies at Cedeplar

Cedeplar (Center for Regional Development and Planning) is one of the main institutes for demographic and economic research in Brazil.

The Institute is holding a seminar on Current Issues and Frontiers in Demographic Methods, on 13 June 2011. The event is in honour of Professor Jose Alberto de Carvalho, who is certainly one of the greatest Brazilian demographers.

The seminar will be followed on 14 and 15 June by the International Seminar on New Challenges in Population and Development, jointly organized with the IUSSP Scientific Panel on New Challenges in Population and Development.

Both seminars will be broadcast live by Cedeplar on 13-14-15 June (see schedules above: Brazil Eastern Time = GMT-3) Click Here for the live video feed.

For more detailed information, click here.

I congratulate Cedeplar for holding this event. We (Brazilian demographers) thank Prof. Zé Alberto for his work!

Brazilian Census 2010: a few more results

The Brazilian Institute of Geography and Statistics (IBGE) released a few more results of the 2010 Brazilian Census. At their website, you can check out a few maps, charts, compared historical data and population pyramids. (hat tip to Ricardo de Sampaio Dagnino)

Cellular automata in your iphone

Now you can have a Cellular Automata (app) model in your iPhone (iPod Touch or iPad). It's the SPEED Sim (aka Spatial Population Ecological and Epidemiological Dynamics Simulator).

Dr. David Hiebeler and his team at the SPEED Lab (Spatial Population Ecological and Epidemiological Dynamics Lab) developed this app that allows you to explore the dynamics of three spatial simulation models.

• Dispersal 2: Population model with local dispersal at distance 1 or 2, and long-distance dispersal.
• SIRS: Spatial epidemiological model.
• Vaccinated communities: Epidemiological model with varying vaccination levels among different communities.

Here you may also access some cellular automata Java applets!
