Data Sources & Methodology.
Where our numbers come from and how we calculate them.
Each moving counter is a model, not a live measurement. Reported figures are historical snapshots. Follow a source link for its original definition and any revisions.
Data attribution and reuse
World Bank data is shown with rounding and, for some counters, adapted into illustrative calculations. See World Bank terms of use ↗. Weather data is provided by Open-Meteo ↗ and displayed as rounded modelled values under CC BY 4.0 ↗. Check the source and terms for each dataset before reuse.
Historical comparisons
The homepage compares headline inflation in August 2026 (15.39%) and September 2026 (14.63%); petrol in April 2026 (₦1,532.93 per litre) and May 2026 (₦1,596.25); and unemployment in Q1 2024 (5.3%) and Q2 2024 (4.3%). Inflation is year-on-year and unemployment is the share of the labour force. Comparisons use published values, not a forecast.

State fuel price comparison
Selected state averages for petrol (Edo ₦1,722.91; Adamawa ₦1,469.83) and diesel (Nasarawa ₦3,785.84; Kogi ₦2,823.85) verified in the original National Bureau of Statistics May 2026 price watches. They are historical averages, not current station prices. Only four state figures are included; an unavailable value means it has not been verified for this tool.
