When two sources disagree, the higher tier prevails and the conflict is recorded on the affected metric.

1
Kenya National Bureau of Statistics
Primary for national and subnational official statistics.
2
Central Bank of Kenya
Primary for monetary policy and financial-stability context.
3
County government plans and records
Primary for local planning and regulatory context.
4
World Bank / IMF / UN-Habitat / AfDB / IFC
Primary for international comparison; secondary for Kenyan statistics.
5
Licensed market data providers
Used for comparables where official evidence is unavailable.
6
User and partner evidence
Deal-specific only; never generalised to market statistics.

Published openly, because a stated gap is more useful than a confident-looking estimate.

Comparable evidence relies on listings and valuations, so pricing confidence is capped at Moderate.

Nearest reliable proxy: Official residential price indices plus valuation reports where available.

Rental yield estimates outside Nairobi and Mombasa are marked Limited or Insufficient.

Nearest reliable proxy: County income and urbanization indicators, reported as context only.

Physical-risk scoring is withheld until a licensed layer is connected.

Nearest reliable proxy: Open elevation and river-network data, indicative only.

Large parts of the market are not captured by any connected source.

Nearest reliable proxy: Census housing-stock characteristics and survey-based estimates.

Ingestion rules the platform applies before any dataset reaches a user-facing screen.

No scraping of sources whose terms prohibit it; licensed feeds stay blocked until a licence is executed.
Personal data is minimized, and Kenya's Data Protection Act obligations govern retention and access.
Every ingestion run records source, retrieval time, transformation and validation outcome.
Partner and user documents are deal-scoped and never generalized into market statistics.
Failed validation halts publication of the affected metric rather than degrading it silently.
Access to documents and audit records is permissioned by role and fully logged.
