A cost of living index for Spanish cities

Abstract

Citizens’ well-being depends both on their income levels and on the cost of living in their specific place of residence. However, very limited data are available on differences in price levels across geographical areas within a single country. This article presents a price index for Spanish urban areas covering the period 2004-2020. By way of example, according to this index, the cost of living in the two largest cities (Madrid and Barcelona) in 2020 was nearly 20% higher than the average of other Spanish urban areas. Thus, while average private sector wages in Madrid and Barcelona were 45% higher than in other cities, this gap narrows to 21% when wages are adjusted to reflect purchasing power.
