Data Competition

Contest Overview

The Africa Statistics Day 2025 Data Challenge is a lively innovation event that celebrates Africa Statistics Day on 18 December 2025. This year, the National Bureau of Statistics leads a strong initiative called the NBS Data Challenge. It gathers creative people from all over Tanzania to turn data into actual solutions. The Tanzania Startup Association (TSA) supports it.

The Data Challenge brings together innovators, students, startups, and public servants to tackle daily problems with data. By mixing the National Bureau of Statistics rich data sources with the drive of Tanzanian innovators, we highlight data's power to help make smarter choices in areas like health, education, agriculture, climate, econonics, and finance. This event goes beyond just coding—it focuses on creativity, solving problems, and working as a team.
