The AI use case
How we built it with AI, step by step
From a question to a live app: AI-assisted engineering with every number traceable to an official source.
Data spec
We defined the questions, measures and age groups with AI, then reviewed them against the UN definitions.
Reproducible pipeline
Raw files come from the official UN WPP 2024 package, World Bank and Gapminder, each pinned to a version and checksum.
Interactive app
A fast D3 app with accessible controls, data tables for every chart and honest labels for estimates and projections.
Kept current
The pipeline checks for a new UN edition twice a year, so the atlas updates without a rebuild by hand.
