Before comparing two countries, check what the numbers measure.

An international property ranking can look precise while combining measures that are not equivalent. A national index, a capital-city series and a collection of asking prices can describe very different experiences.

The Bank for International Settlements maintains detailed residential price data with regional and property-type breakdowns for around 60 economies. Its selected series aim to improve cross-country comparison by choosing a representative indicator for each jurisdiction, generally the closest available to national coverage.

The BIS provides both nominal and inflation-adjusted measures. It also explains that underlying series vary in coverage, frequency and methodology. Those notes are essential context when reading a comparison.

Use a three-question check: What properties are included? What place does the figure cover? Is the change expressed before or after inflation? Then examine the reference period. Our editorial approach is to make those differences visible rather than treating every percentage as interchangeable.

This is a global data-literacy guide. It does not rank countries as investment destinations or forecast price growth. Local transaction rules and property-specific research require separate attention.
