Links roundup

A few things that passed across my rss feed/tweetdeck/other input strand recently:

• Thoughts on predicting which mega-urban areas are most vulnerable to epidemics (h/t Matt Watson, @BioAndBaseball).
• Kings Fund study finds increasing inequality in behavioural risk factors by income & education (cf Victora’s Inverse equity hypothesis).
• A new data visualization tumblr from the World Bank.
• An brief-ish article (paywalled, sorry) that promos a new book on envisioning Public Health ecologically, from two UK Food Policy researchers.
