Spain map by province and municipality

How to use it

Pick what you want to see under “Data” and the map recolors right away. Hover over a province, or tap it on your phone, to see its value, its rank and the rest of its numbers. Below the map you’ll find the legend and the 10 highest and lowest.

To see municipalities, tap a province and press “See its municipalities”, or choose it under “Province”. “Municipalities” shows all of Spain’s at once (it takes a little longer: that’s a lot of shapes). The Canary Islands sit off the southwest; use the “Canary Islands” button on the map to jump there. The page address keeps your view, so you can share it as is.

Provinces, municipalities and INE codes

Spain is split into 17 autonomous communities (regions such as Andalusia, Catalonia or Madrid) and two autonomous cities in North Africa, Ceuta and Melilla. The communities are divided into 50 provinces, which are older and smaller: most are named after their capital city, like Seville or Valencia, and some communities, like Madrid or Asturias, are a single province.

Each province is made up of municipalities (municipios), the local councils that cover every inch of the country, from Madrid with over three million people to villages with a few dozen. There are 8,132 of them, so they’re much smaller than a US county: closer to a township or a small town with its farmland around it.

The INE (Instituto Nacional de Estadística) is Spain’s national statistics office. Every province has a two-digit INE code and every municipality a five-digit one: the province code plus three digits, so 28079 is the city of Madrid (28) and 08019 is Barcelona (08). The CSV download uses these codes, which are the safe way to join your own data, since some names repeat across provinces.

What the map shows

Spain had 49,114,494 people on January 1, 2025, according to the municipal register, or 97.1 people per square kilometer. Leaving out Ceuta and Melilla, the densest province is Madrid (889.1 per km²) and the least dense is Soria (8.8 per km²).

From 2015 to 2025 Spain grew 5.3%, but not everywhere: 20 provinces have fewer people today than ten years ago. Guadalajara grew the most (+12.5%) and Zamora shrank the most (−9.9%).

By municipality the gap is even wider: 4,850 of those that existed in 2015 (60%) lost people, mostly small villages in the interior. Among those with at least 1,000 people, Yebes (Guadalajara) grew the fastest, by 105.7%. Among those with over 10,000, the densest is Mislata (Valencia), with 23,192 people per km².

How the colors work

Population, density and area use six colors split by rounded quantiles: each color holds about the same number of provinces or municipalities, and the breaks are rounded to easy numbers. They’re recalculated for what you’re looking at, so the provinces and the municipalities of one province each get their own.

Population change uses fixed breaks: gray for those that barely changed (between −1% and +1%), green for those that grew and brown for those that shrank, darker as the change gets bigger (over 5% and over 10%). Every scale goes from light to dark, so it still reads in grayscale or printed in black and white. Areas are in square kilometers, as the official figures are (1 km² is 0.386 square miles).

Where the data comes from

Population is the official figure from the Padrón, the municipal register every resident of Spain has to sign up in, as of January 1 of 2025, 2020 and 2015, published by the INE. Each municipality’s area comes from the Nomenclátor Geográfico de Municipios of the IGN (Instituto Geográfico Nacional, Spain’s national mapping agency), and the boundaries from its database of administrative divisions, simplified so the map loads fast. Density is population divided by area.
