FAQ
What if two cities are statistically similar?
When fewer than three meaningful differences exist, the verdict says so plainly — the choice comes down to preference. Near-identical comparisons are marked non-indexable but the side-by-side data is still shown.
How are the differences ranked?
Metrics are ordered by normalized delta — the size of the gap relative to the typical range for that metric — so the most decision-relevant differences surface first.
Why do some metrics use community data?
Where no official or trusted-aggregator source exists for a metric, community data such as Numbeo is used and graded D. Treat D-grade rows as indicative, not authoritative.
How is this comparison built?
It places the two city records side by side. Detailed metric tables with sources live on each city page; this view links to both.
Is the comparison data machine-readable?
Yes. The pair is exported at /data/compare/porto-vs-brno.json.
