Where the readings come from
Sources
naijaOS groups its inputs by type, so you always know whether a figure is official, reported, legal, or a market signal — and how much weight to give it.
§ Official data
NBS
National Bureau of Statistics — inflation, food prices, transport indices, labour and household data.
CBN
Central Bank of Nigeria — exchange rates, policy rate, monetary circulars.
CAC
Corporate Affairs Commission — business registration, company records, filings.
NNPC
Petroleum pricing and supply notices.
NERC
Electricity tariffs and regulatory orders.
Govt portals
Ministries, agencies, and official gazette channels.
§ Reported data
Reputable Nigerian newspapers and business publications, used for events and context and identified as reported — not as primary measurement. Where reported figures and official releases differ, the official release governs.
§ Legal & institutional
Statutes
Acts of the National Assembly and state laws relevant to everyday risk.

Fare and logistics-cost indicators.
User caution
Every figure on naijaOS must be checked against the current official release before you rely on it. Data moves; a number that was right last quarter can be wrong this week. Each published figure should identify its source and relevant date. When in doubt, go to the primary source.
On linking. naijaOS points to source types and named institutions rather than embedding figures it cannot keep current. For any specific number, consult the named institution’s latest release directly. How we handle sourcing →
