Executive summary: GDP statistics from developing countries, particularly in Africa, are far less reliable than commonly assumed due to severe data collection limitations and statistical capacity constraints, suggesting we should treat these numbers with much greater uncertainty and explicit error margins.
Key points:
Statistical agencies in many African countries lack basic capacity to collect data, often relying on outdated censuses and crude estimations
Major GDP revisions (e.g., Nigeria’s 89% overnight increase in 2013) reveal the scale of potential measurement error
Informal sectors (≈60% of working people) are typically estimated as a simple function of population, which itself is often poorly measured
Statistical error margins for developing country GDP are estimated at 20-35%, with growth rate errors of at least 3%
Recommendation: GDP statistics should include explicit margins of error (e.g., “2.9% ± 5%”) to better reflect uncertainty
