Phoenix (suburbs) urbanzation 1989 - 2009

These images (taken by NASA) show the urbanzation of Chandler (the fastest-growing satellite city on the outskirts of Phoenix).

ps. 1-  According to NASA: ""Chandler grew from just 3,799 residents in 1950 to 176,581 residents in 2000, based on 10-year census figures." That's an average population growth rate of 8% per year (over a fifty-year period!!!)

ps. 2 - Would you call it 'urban sprawl' ?

If you like this kind of map you should take a look at the experts: World Mapper and Views of the World.

Parking Rates Worldwide

Colliers International (a big real estate company) did an international survey on the cost of car parking. The results are presented in the chart below, which shows the monthly cost of parking rates. (via The Drunkeynesian)

What caught my attention:

• Prices that are too low (in my almighty opinion of course): Bangkok , Delhi, Jakarta,Mumbai, Buenos Aires, Rio de Janeiro, Los Angeles, Seoul, São Paulo, San Diego, Santiago, Beijing, Mexico City, Istanbul and Atlanta.
  
  
• Prices that are too high: _________.

Urban Mobility solutions

You have probably heard about congestion pricing before. Now you should know these 'new solutions' for urban mobility that deserve our attention:

1. Loyalty mileage program for Public Transit. Great idea! (thanks Leo for the tip)
   
   
2. Cash lotteries for off-peak commuters (here)
   
   
3. Discard your car and get free public transit for life (via BBC Brasil)

Contrasting Flickr and Twitter Locations

Erich Fisher came up with a new great visualization of web data. The maps highlight where people post geo-tagged photos to Flickr (red) from and geo-tagged tweets to Twitter from (blue), or both (white). (via Information Aesthetics)

What I like particularly about this kind of map is the way it unveils urban hierarchy.

Could it tell us somthing about urban centrality?

Evolving population pyramids

Jorge Camoes came up with this strange idea of an alternative way of representing population pyramids. Check it up!

Looking good!

I have tried something "similar". But it's not looking that good...

This chart shows the evolution of the population pyramid (Brazilian male engineers) from 2000 to 2020. Darker lines represent the earlier projection years*.

*That's the aging (and dying) process isolated. In a future post, I'll present the projection results including the trends in the number of graduated students every year.
