- There is a massive economic gap between municipalities like Pozuelo de Alarcón and southern towns like El Ejido.
- Madrid and Barcelona lead in income among large cities, although Madrid has the greatest internal inequality.
- Income per capita has grown significantly more than income per taxpayer since 2019.
If you've ever wondered how money is distributed across Spain, analyzing personal income in Spanish municipalities is the best way to understand it. It's not just about cold, hard numbers, but a social snapshot that reveals where wealth is concentrated, which towns are thriving, and where the economic gap is widening, based on real data from personal income tax returns.
To understand these figures, it is essential to differentiate between income per taxpayer and income per capita, since the income of each individual taxpayer is not the same as the average income when including children and non-taxpayers. This analysis, supported by comprehensive databases such as those from Fedea and the Personal Income Tax Return Statistics (EDM) , allows us to see the evolution of the local economy within the common tax territory, excluding the Basque Country and Navarre due to microdata access limitations.
The current state of income and inequality
Looking at the most recent data, we see that average income in municipalities with more than 5.000 inhabitants has risen slightly, reaching around €25.308 per taxpayer . Interestingly, although income has increased, inequality within municipalities has also risen by 2,16%, meaning that the distribution of this wealth has not been entirely equitable.
One striking statistic is that per capita income has grown much more sharply than income per taxpayer, reaching €13.569. Comparing the current situation with the pre-pandemic period, specifically 2019, we see that per capita income has jumped by 22,76%, while income per taxpayer has fallen short, increasing by only 9,79%.
Analysis of major cities and centers of wealth
When we talk about the most populated cities, there's no surprise: Madrid and Barcelona remain at the top. Madrid leads the table with an average income exceeding €36.000, followed very closely by the Catalan capital. However, it's not all growth; while cities like Las Palmas de Gran Canaria and Murcia have seen their incomes rise, Seville has experienced a slight decline.
Regarding inequality, Madrid stands out again, but this time for having the highest Gini coefficient , indicating a vast gap between the richest and poorest. Conversely, Zaragoza ranks as the most balanced major city in terms of income distribution.
The municipalities that mark the extremes
If we look at municipalities with more than 50.000 inhabitants, one name appears year after year at the top: Pozuelo de Alarcón . With an average income approaching €77.451, it's the highest-earning place in Spain, followed by Boadilla del Monte and Sant Cugat del Vallès. What's most striking is the gap with the other end of the spectrum; municipalities like El Ejido have significantly lower incomes, with Pozuelo's being more than five times higher.
It's important to note that earning a lot doesn't mean everyone lives well. In fact, Pozuelo and Alcobendas have some of the highest inequality rates . On the other hand, towns like Sant Boi de Llobregat and Cornellà de Llobregat show a much more homogeneous and equitable distribution of wealth.
How are these data actually calculated?
To avoid confusion, it's important to clarify that average gross income includes everything: salary, profits from movable or immovable capital, business activities, and even tax-exempt income. It's not an individual figure; rather, it depends on whether the family filed a joint or individual tax return. Therefore, it should be analyzed as income per return to avoid common errors in tax filing.
In addition, there is what is known as average disposable income , which is basically what is left in your pocket after paying income tax and social security contributions. To organize this mountain of data, municipalities are usually classified by population brackets, from those with over 100.000 inhabitants to small towns with between 1.000 and 10.000 residents.
Dynamics of territorial growth and decline
Economic development is not uniform across the country. Some areas have experienced a genuine boom, such as Marbella, Estepona, and Ibiza , where incomes have risen by almost 20% in recent years. On the other hand, some towns have suffered significant drops in their average income, as is the case in Torrelavega and Calvià.
This territorial analysis reveals that the Spanish economy is a mosaic of contrasts. While some municipalities consolidate their position as high-income enclaves , others struggle to improve their basic indicators, demonstrating that geographical location remains a determining factor in citizens' standard of living.
Income in Spain is distributed very unevenly, with a massive concentration of wealth in specific municipalities in the Community of Madrid and Catalonia, while inequality remains a persistent problem even in the wealthiest areas. The use of indicators such as the Gini index and the distinction between gross and disposable income helps to understand that economic growth does not always translate into greater social equity at the municipal level.
