GridSample Specialist

Flowminder Foundation

Duration: Fixed term contract (17 months, full time)
Start date: 3 April 2018
Reporting to: GridSample Manager

Flowminder is a unique, startup-like non-profit that develops advanced technological solutions to address humanitarian problems. Our work is an exciting blend of software development, data analytics, academic research, and international development, that takes place in a dynamic and highly collaborative environment.

The Flowminder Foundation has an exciting opportunity for a survey practitioner to play a key role in a Gates Foundation-funded gridded population survey evaluation in Nigeria, and develop foundational training materials for the emerging field of gridded population sampling.

Gridded population survey sampling is an emerging method, used most often when census data is outdated or inaccurate. Survey teams also consider gridded population sampling to perform spatial population sampling and to select sampling areas that are smaller or larger than standard census sampling units. The GridSample R algorithm or web tool have been used in numerous surveys, including in DR Congo, Mozambique, Somalia, Nepal, Bangladesh, and Vietnam. (beta version) was launched by Flowminder/WorldPop in 2017 to select household survey sampling areas from gridded population data.This web tool allows for the selection of dozens of complex survey designs with a click-and-point interface and preloaded datasets. The website outputs boundaries of sampling areas, that can be easily mapped in ArcGIS or Google Maps, and the population values needed to calculate survey sampling weights.

New users are already survey practitioners who need training and technical assistance to learn about gridded population sampling methods and tools, and consider their pros and cons across diverse, complex settings.

We help save lives and improve welfare by providing analyses and decision support to all relevant parties based on the latest academic advances. Our work includes both research and operational projects, always aimed at having a concrete impact on vulnerable populations. Our multidisciplinary team include demographers, medicals doctors, epidemiologists, geographers, mathematical modelers, sociologist, economists and computer scientists. Our funders include the Bill and Melinda Gates Foundation, DFID, World Bank, World Food Programme, UNFPA, UN Foundation and others.

Our success in this area stems from the ability of our teams to:

  • design and utilise cutting-edge research and analysis methods
