I have long followed Hans Rosling's "Gap Minder" project (http://www.gapminder.org/), and was recently delighted to discover Ana Rosling Rönnlund's "Dollar Street" project (http://www.gapminder.org/dollar-street/). The Dollar Street project seeks to illustrate through photographs the relative living conditions of people based on their socio-economic status. I expect most of us inherently understand that living standards are more a function of socio-economic status than country of residence, but it is truly interesting to see this borne out in photographs. The challenge is of course in capturing, categorizing, accessing and analyzing these photographs, but this is a challenge we are certainly capable of overcoming with today's Big Data technologies. Happy viewing!
