Tanzania’s National Bureau of Statistics has just released a huge batch of data from the 2012 Census. I will dig into this over the coming weeks and months, but here are some charts to get started.

My old colleagues at WaterAid have put together this interesting map of water and sanitation access across Africa. It shows trends in access to clean and safe water and improved sanitation by country.
