This map displays all RAAB surveys since 2000 at the level of their geographic sampling areas. Where survey data are available, vision impairment and effective cataract surgical coverage indicator values can be seen via the Filter menu in the top left hand corner.

RAAB survey sampling areas are represented by national and sub-national administrative boundaries available via OpenStreetMap (under the Open Database Licence). Note, not all RAAB sampling areas are currently available, but the map will be updated with new information when possible.
