The survey was conducted as a partnership between the Tanzanian Government, and NGOs: the Institute for Security Studies (ISS), Saferworld and the Security Research and Information Centre (SRIC).

The survey project was conceptualised by Jakkie Potgieter, with the assistance of Dominic Hayuma, Jerry Kitiku and Paul Eavis, while responsibility for the management of in-field logistics, the selection of sample areas and the validation of the research process was shared equally between the four.
