Urban Picture

This is a picture of Vila Amaury, a temporary village of 16,000 people in Brasilia - Brazil. Most of those people were construction workers who built public buildings in the city, including some ministries and the National Congress, the tall building you see in the picture. (ht Telmo Ribeiro)

The village was later covered by the water when the Paranoá River was dammed to create an artificial lake.

Global Grid of Probabilities of Urban Expansion to 2030

Karen Seto and her group at Yale have recently made available a dataset of Global Grid of Probabilities of Urban Expansion, which presents spatially explicit probabilistic forecasts of global urban land cover change from 2000 to 2030 at a 2.5 arc-minute resolution. This is the dataset they used in their PNAS paper we have mentioned back in 2012.

Thanks Marcia Castro for the pointer.

Japan's aging population in R

Here is a nice GIF showing the population aging of Japan, and here is the script to make this animated population pyramid in R using ggplot. 

Kudos to Kyle Walker, author of this code and who you should definitely follow on Twitter and GitHub if you're interested in R, spatial analysis, data visualization and demography.
