A case in six queries

The Vanishing Economy.

Between 2022 and 2024 Egypt’s GDP fell by 18%. Over exactly the same two years, it rose by 68%. Both numbers are real, both come from the same source, and nothing about the country changed in between. Find out why — in six SQL queries, in your browser.

About ten minutes. No signup, no install, nothing to download. Every figure is real and cited.

Warming up the SQL engine…

Where every number came from

Check it yourself.

This case is an investigation, not a story. There is no invented detail in it — no fictional characters, no dramatised events, no rounded-up figures. Every value you queried is a published number you can verify.

These are the same cited tables the 123 practice challenges run on — one source of truth, not a copy made for this page. The SQL engine is SQLite compiled to WebAssembly and runs entirely in your browser; nothing you type is sent anywhere.
