Methodology

Cost data (meal, rent, fuel, mobile data, beer, movie) comes uniformly from Numbeo for every city. Each Numbeo source row below shows the contributor count and last-update date so you can verify sample size. Earnings come from per-city primary sources: statutory pay rates and government wage data, regulator reports, national statistics offices, Fairwork country reports, and named collective agreements. Self-reported salary aggregators (Glassdoor, Indeed, ZipRecruiter, PayScale, Salary.com) are blocklisted as primary earnings sources and CI rejects them, where a city was historically sourced that way, it is labelled LOW until it is re-sourced.
