Flowminder is seeking a consultant who will develop and coordinate a telephone survey to be conducted in DRC. The aim is to enable data triangulation between Call Detail Record (CDR) data, microcensus data and phone survey data, in order to support the production of mobility estimates.

Background Information

The Mapping for Health in DRC project aims to strengthen the effectiveness and equity of vaccination interventions in the Democratic Republic of the Congo (DRC) through the provision of technical assistance for the development of micro-plans, and harmonised and integrated spatial demographic and health data. Mapping for Health in DRC is led by the Ministry of Health, coordinated and implemented by Flowminder, the Center for International Earth Science Information Network at Columbia University (CIESIN), the WorldPop research group at the University of Southampton and other partners. Mapping for Health in DRC is a continuation of previous GRID3 (Geo-Referenced Infrastructure and Demographic Data for Development) work in the DRC.

As part of the project, Flowminder will design and commission a telephone survey in collaboration with the mobile network operator Vodacom. The phone survey will specifically invite Vodacom clients in DRC to participate, to assess the ability of Call Detail Records (CDR) data to inform in-country population mobility estimates. The results of the phone survey will be anonymously linked to respondents' CDR traces (where consent is given) and compared with microcensus data.

The implementation will be undertaken by a survey implementation organisation (the “implementing organisation”).
