A transforming demographic landscape
The latest municipal census of Madrid, updated as of January 1, 2026, reveals that the Spanish capital maintains a population of 3,497,277 inhabitants, consolidating its position as the second most populous city in the European Union, surpassed only by Berlin. However, this positive figure is overshadowed by a reduction of 30,647 registered residents, representing a decline of 0.87% compared to the previous year.
The City Council argues that this decrease is due to adjustments in the census and regulations that have eliminated nearly 100,000 registrations. Despite this, there is a glimmer of hope: for the first time in six years, Madrid has recorded a positive natural growth with 27,097 births, surpassing the 26,533 deaths.
Despite overall growth in some districts, the heart of Madrid is experiencing a notable population loss. The Centro district has seen 4,549 residents disappear, raising questions about the sustainability of the area amid tourist pressure and high real estate costs. This phenomenon is accompanied by negative natural growth affecting approximately 2,700 people.
As Madrileños seek more affordable alternatives, many have opted to move to other districts or even to nearby towns like Toledo or Guadalajara. In total, there were over 111,000 changes of residence within the municipality. The districts most affected by this migration are Ciudad Lineal and Salamanca, with significant population declines.
Despite the discouraging outlook for some traditional areas, districts like Barajas and Vicálvaro are experiencing demographic growth thanks to new urban developments. Barajas has added 74 new residents, while Vicálvaro has seen its population increase by 2,627 inhabitants, driven by projects like El Cañaveral.
As Madrid navigates these significant demographic changes, it is evident that the city is undergoing a profound transformation in its population structure. With nearly 30% of its inhabitants concentrated in the most densely populated districts like Carabanchel and Puente de Vallecas, the capital will need to adapt to face future challenges related to housing, public services, and quality of life.
