Layer 1
Source records
Datasets, indicators, and records come from Data Civic. Public sector pages consume those records rather than maintaining a separate copy of the same evidence.
Methodology
The trust model behind infrastructure.civic.ng.
The platform separates verified source data, derived analysis, and experimental product features so users can tell what is observed, what is calculated, and what is still a prototype.

Core rule
A compelling interface never upgrades weak evidence into a stronger claim. Scope, source, and derivation stay visible even as the product becomes easier to use.
Layer 2
Derived analysis
Computed values are allowed only when the transformation is documented and the result is clearly distinguished from an official source statistic.
Layer 3
Product experiments
Features such as Power Business forecasts may use synthetic or modelled data for product validation, but they remain explicitly separated from the public evidence layer.
How pages are built
One evidence layer, multiple public views
infrastructure.civic.ng reads infrastructure datasets, indicator definitions, and record series from data.civic.ng. The sector pages then present those records as readable summaries, trends, comparisons, and state views.
The site does not silently fill gaps. Missing state data remains missing. Missing years are not interpolated. A national indicator is not restated as an LGA or state outcome.
When a derived series is used, such as road length by state, the page labels it as derived and keeps the methodology boundary visible.
Evidence labels
What the labels mean
- Official
- A measure published as an official statistic or inventory by an authorized public institution.
- Institutional
- A series maintained by a recognized institution and exposed through Data Civic, even when it is not an official Nigerian government statistic.
- Derived
- A value computed from source data using a documented method. Derived results remain distinct from official source inventories.
National vs state
Scope follows the records
Power, telecom, and water currently use national series. Roads have one state-backed derived series. State pages only show a sector when verified state rows exist for it.
Experimental boundary
POCs do not become public evidence
Synthetic forecasts, demo feeders, simulated outages, and sample business savings in Power Business are product-validation artifacts. They are not silently mixed into public infrastructure claims.
Scope and limitations
- National indicators should not be restated as state, LGA, neighbourhood, utility, or household outcomes.
- Derived road-length values should not be interpreted as road condition, quality, maintenance, accessibility, or government performance.
- State pages activate only where verified state rows exist upstream.
- Experimental product features remain separate from source-backed public claims until their inputs and methodology are independently supportable.
