Quote of the Day

Somebody Else’s Problem (SEP):
"An SEP is something we can't see, or don't see, or our brain doesn't let us see, because we think that it's somebody else's problem.... The brain just edits it out, it's like a blind spot. If you look at it directly you won't see it unless you know precisely what it is. Your only hope is to catch it by surprise out of the corner of your eye. [...] it relies on people's natural predisposition not to see anything they don't want to, weren't expecting, or can't explain."
(Douglas Adams in his novel Life, the Universe and Everything)

The same is true for scientific discoveries.

IPUMS-International and Brazilian census microdata

Imagine what research questions you could answer if you had in your personal computer the census microdata of several countries around the world. I am talking about over 211 census from over 68 countries  - for some countries, every census round since 1960 is available. This is made possible thanks to the IPUMS-International project. 

They do this huge effort "to inventory, preserve, harmonize, and disseminate census microdata from around the world. The project has collected the world's largest archive of publicly available census samples. The data are coded and documented consistently across countries and over time to facillitate comparative research. IPUMS-International makes these data available to qualified researchers free of charge through a web dissemination system"

By the way, Robert McCaa alerted me that the 2010 sample of the census of Brazil is now available for download at IPUMS website. Enjoy it !

13th WCTR + Commute Time in Brazil




Dear readers, next week I'll be in Rio for the 13th WCTR. I'm presenting a working paper Tim Schwanen and I have recently published. In this study we explore 18 years of commute time trends in Brazil. I was planning a dedicated post to talk about this study but I've been quite busy these days. 


So here it is. You may download it here:

European shipping routes between 1750 and 1800

James Cheshire (UCL) have used R to create this incredible map showing some European shipping routes between 1750 and 1850. What struck me most is the existence of a remarkable dataset like this, containing digitised information from the log books of ships.
