"This platform aggregates 12,100 records across 122 indicators from the CBN, NBS and World Bank into a single interactive dashboard, with a separate free Open API for programmatic access — making Nigeria's public economic data accessible to researchers, developers, students and the general public."
This platform aggregates 122 indicators across eight data groups from three official public sources — the Central Bank of Nigeria (CBN), the National Bureau of Statistics (NBS), and the World Bank. The primary case study period is 2020 to 2026; select groups (the CBN Five-Year Financial Statement, Currency in Circulation, and Real GDP by Sector) extend further back, to 1960. The dashboard presents the data through interactive Chart.js charts, sortable data tables, and a live analytics page, running directly against a public Supabase PostgreSQL database — no custom backend mediates the dashboard's own data access. A separate, independently-deployed Python FastAPI Open API at npedata-api.onrender.com/api/v1 provides free, documented, third-party programmatic access to the same dataset.
This project was developed as a Final Year Project at Caleb University, Imota, Lagos, in the Department of Computer Science. Its contribution is a free, open-source, and academically documented implementation built on a teachable technology stack. The database contains 12,100 records across 122 indicators, covering GDP sectoral breakdown (57 sectors, 1981–2024), multi-currency CBN rates (11 currencies), FX reserves, the CBN balance sheet, NFEM daily rates, and the core macroeconomic indicators.

This system is for informational and educational purposes only. Data is sourced from official institutions but cannot guarantee freedom from errors or omissions. This system does not constitute financial advice. For official economic data, refer directly to the CBN, NBS, and World Bank websites. A June 2026 data audit found 1,435 duplicate records across 1,232 indicator/date pairs introduced by repeated ETL runs (reducing the total from 13,535 to 12,100); all were reconciled against original CBN/NBS source files and resolved.
