How we rank countries

The method in short

Each tab scores a country from 0 to 10. Every component is converted to a 0 to 1 value, multiplied by its weight, and averaged over the weights that have data. The result is multiplied by ten. Components where a lower number is better, such as tax rates and monthly costs, are inverted before scoring.

Before normalization, each component is winsorized at the 5th and 95th percentiles across the eligible countries. That stops one outlier from flattening everyone else. A country at or above the 95th percentile reaches the top of that component, which is why several countries can share a 10.0 on a tab.

A country is eligible for a tab only when every required component exists and the components with data cover at least 70 percent of the total weight. Ineligible countries are left out of the ranking, not placed last. Ties break on the overall score, then on the country name.

Travel advisories act as a gate. The tabs that decide where to live, retire, digital nomads, best value, families and easiest residency, drop any country at advisory level 3 or 4. Low tax, healthcare and climate compare published numbers, so only a level 4 (do not travel) advisory removes a country there. A country with no advisory on record is not excluded.

Where the numbers come from

• Cost of living, healthcare, safety, quality of life, pollution and purchasing power: published Numbeo country indices.
• Internet speed: the Speedtest Global Index fixed-broadband median, not mobile.
• Visa income thresholds, tax rates, residency and citizenship paths: the country record, sourced from government publications.
• Rent, groceries and school fees: published survey figures, shown as estimates in US dollars.
• Visa income thresholds in local currency are converted at one exchange-rate snapshot. The date of that snapshot is shown above.

What this cannot tell you

• Four countries are not scored anywhere: Antigua and Barbuda, Burkina Faso, Togo and Northern Cyprus. Numbeo publishes no cost of living or quality of life index for them, so they cannot reach the completeness gate. Their published values still appear on their country pages.
• Indices such as healthcare and safety are perception measures from survey responses, not audits. A strong national system can still be thin in a rural area.
• Figures are country averages. City pages carry city-level numbers, and those can differ sharply from the national figure.
• A high score is not advice. Visa rules, tax residence and healthcare eligibility depend on your nationality, income and family, and they change.
