Crowdsourced Data

How the composite score is calculated

Every country and city is scored 0-100 by an equal-weight composite of three crowdsourced pillars. Higher is better. The weights are fixed and identical for every row.

Composite = 100 × mean( norm(savings) , norm(lifestyle) , norm(people_supported) )

norm(x) = (x − min) / (max − min)     # min & max taken across all ranked
                                      # countries (or cities), per pillar

The three pillars (one third each)

• Yearly savings: euros kept per year after tax and cost of living (absolute euros).
• Lifestyle level: self-reported quality of life, scale 1 (frugal) to 3 (luxurious).
• People supported: how many people the income supports (household-size signal).

• Each pillar is min-max normalized across the ranked set, so a score is relative to the other places shown, not an absolute index.
• The score always uses absolute euro savings. The "Savings as % of income" switch is a display view only and never changes a ranking.
• Rows backed by fewer than 25 submissions show their submission count in amber (indicative, not definitive) and can be hidden with the "At least 25 submissions" option.
