Global Cost Data is an independent research site dedicated to
providing accurate, data-driven cost of living comparisons
across countries worldwide.
Every figure published on this site is sourced from official
public datasets — primarily World Bank Open Data and Numbeo’s
Cost of Living Rankings. We never publish estimates without
a cited source.
Our flagship metric, the Expat Value Score, is a proprietary
calculation combining World Bank GNI per capita (PPP) with
Numbeo’s Cost of Living Index to measure the real purchasing
power advantage for foreign income earners in each country.
This site is built for expats, digital nomads, retirees and
anyone considering relocating abroad who wants reliable data
rather than anecdotes.
Data is updated annually. Last update: 2025.
