Africa's first nationally representative mobile phone survey launches in Kenya.

As debate continues about a recently introduced tax on all SIM cards in Tanzania, Sauti za Wananchi contributes the most recent nationally representative data of the issue.

Until now, the only types of data that have been available to provide insight into national realities are administrative or survey data. Administrative data often suffer from quality issues and survey data are costly in terms of resources and time. Sauti za Wananchi provides new infrastructure to address these challenges. A nationally representative sample of citizens can be contacted regularly through mobile phones, to provide opinions and report on local realities.
