I‘m working with a small team on a new project to produce independent population and GDP estimates for African countries. Published figures for many countries are outdated, modelled from sparse data, or rely on censuses that are decades old1. These numbers underpin many development metrics and funding decisions, and we think there’s good reason to assume some are significantly off.
The plan is to combine satellite imagery, administrative data and other sources to produce estimates with explicit uncertainty ranges, published on a public website with full methodology.
We already have a few interested funders and advisors, but we’re looking for more people to get involved (paid or volunteer). If any of the below sounds like you, fill out this short form.
Research
Satellite/geodata experience, population estimation, economics, or your own ideas about how to estimate these figures
Project management
Coordinating across researchers, funders and comms
Comms/marketing
Helping the output reach the people who could find it useful
Funding
We have early donor interest but are open to more
Just want updates
Happy to keep you in the loop
Reviews of How Africa Works by Joe Studwell
Compelling but incomplete application of the East Asian development playbook
The inverse farm size-yield relationship may not be universal
Africa’s manufacturing prospects face headwinds (automation, Asian competition) that Studwell underweights
Saarthak Gupta for Works in Progress
Agricultural case is the book’s strongest element, but manufacturing pillar is thin, none of the four case studies validate it convincingly
Global conditions that enabled East Asian industrialisation (US absorbing exports, large wage differentials, labour intensive manufacturing) no longer hold
Feyi Fawehinmi and Tobi Lawson
Studwell’s demographic determinism is overstretched, arguing his low population density thesis underweights agency, wage dynamics and policy choices
Studwell underweights education as a driver of development and is overly bullish on Ethiopia/Rwanda’s industrialisation prospects
