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. The first shows household access to improved sources of drinking water by region, the second does the same for improved sanitation.
These charts have been designed using Tableau.
And for completeness, it’s worth listing the different types of water source (and latrines) that are counted as “improved”, by the WHO and UNICEF. The 2012 census questionnaire matches these lists almost exactly.
|improved water sources||unimproved water sources||improved sanitation||unimproved sanitation|
|Piped water into dwelling||Unprotected spring||Flush toilet||Flush/pour flush to elsewhere|
|Piped water to yard/plot||Unprotected dug well||Piped sewer system||Pit latrine without slab|
|Public tap or standpipe||Cart with small tank/drum||Septic tank||Bucket|
|Tubewell or borehole||Tanker-truck||Flush/pour flush to pit latrine||Hanging toilet or hanging latrine|
|Protected dug well||Surface water||Ventilated improved pit latrine (VIP)||No facilities or bush or field|
|Protected spring||Bottled water||Pit latrine with slab|
