The 2026 index covers 1,000 cities, drawing on current data and forecasts. Madrid ranks 30th, while Barcelona is 72nd.
The gap is wide. Madrid scores particularly well for human capital, with strong marks for its environment and quality of life. Barcelona's clearest strength is quality of life.
Oxford Economics measures five areas: economics, human capital, quality of life, environment and governance. The index looks beyond the size of a city's economy, weighing living conditions and how institutions are managed.
Oxford Economics calls its method a holistic assessment. It combines economic structure with labour-market and talent indicators, alongside measures of living conditions, environmental performance and governance. Its quality-of-life assessment covers access to culture and leisure, life expectancy, crime, income inequality and housing costs. In a separate best-value comparison, housing is excluded to avoid counting the same factor twice.
Europe accounts for 44 of the 100 cities in the ranking, followed by North America with 34. Spain has two places, giving the list a strong European and North American profile.
Madrid sits 42 places ahead of Barcelona. The difference spans several categories: Madrid pairs a particularly strong human-capital result with positive marks for the environment and quality of life. Barcelona's basic advantage lies in quality of life.
The wider list includes New York, London, Paris, Seattle, San Francisco, Dublin, Boston, Tokyo, Zurich and Oslo. It brings together major business centres and cities known for high living standards across several regions. San Jose is also among the leaders, reflecting the index's inclusion of major North American technology and business hubs alongside European and Asian centres.
Oxford Economics is a major global macroeconomic research firm. Its ranking offers a structured comparison, with assessments based on more than reputation alone. Each city is measured against the same broad categories, giving Madrid and Barcelona a common international frame.
BBC has also described the index as a way to compare cities' functional quality as places to live and work. The ranking does not measure size alone.
For Spain, the result is mixed. Madrid is the national leader at number 30, while Barcelona remains among the 100 cities selected worldwide, at number 72.
The results distinguish the two cities instead of treating Spain's urban performance as one story. Madrid holds the stronger overall position. Barcelona's inclusion confirms its international standing and shows a large gap within the country.
