While Spain’s population has increased slightly since the year 2000, the share of the rural and urban populations has remained relatively constant, with Spain being a highly urban country. This consistently high urbanization is a consequence of both economic and social factors. The Spanish wealth is generated in the cities to a large extent Two thirds of Spain’s economic output, as divided across economic sectors, comes from the service sector, with only ***** percent originating from agriculture. Naturally, service-based economies are easiest when people live closely, while agricultural practices need more land, and thus a rural population. Of course, this also brings economic costs, such as the high living and housing costs in Madrid. What draws people into cities? Social factors also drive people to cities. For some, it is being closer to family or culture, such as art museums. For others, it is finding a large city with green spaces, like Madrid. For others, it is the opportunity to watch a game in a world-class soccer stadium, perhaps FC Barcelona. These and other factors continue to keep Spaniards in their cities.

In 2024, Madrid was the city with the most inhabitants in Spain. In that year, more than 3.42 million people lived in the city. Barcelona was the second-largest city with 1.69 million residents.

Madrid was the largest city in Spain in 2024, with around *** million inhabitants. Barcelona followed second, with nearly *** million people residing there. The most populated city in the Spanish islands that year was Palma de Mallorca.

Population in the largest city (% of urban population) in Spain was reported at 16.99 % in 2024, according to the World Bank collection of development indicators, compiled from officially recognized sources. Spain - Population in the largest city - actual values, historical data, forecasts and projections were sourced from the World Bank on August of 2025.

In 2025, approximately 23 million people lived in the São Paulo metropolitan area, making it the biggest in Latin America and the Caribbean and the sixth most populated in the world. The homonymous state of São Paulo was also the most populous federal entity in the country. The second place for the region was Mexico City with 22.75 million inhabitants. Brazil's cities Brazil is home to two large metropolises, only counting the population within the city limits, São Paulo had approximately 11.45 million inhabitants, and Rio de Janeiro around 6.21 million inhabitants. It also contains a number of smaller, but well known cities such as Brasília, Salvador, Belo Horizonte and many others, which report between 2 and 3 million inhabitants each. As a result, the country's population is primarily urban, with nearly 88 percent of inhabitants living in cities. Mexico City Mexico City's metropolitan area ranks sevenths in the ranking of most populated cities in the world. Founded over the Aztec city of Tenochtitlan in 1521 after the Spanish conquest as the capital of the Viceroyalty of New Spain, the city still stands as one of the most important in Latin America. Nevertheless, the preeminent economic, political, and cultural position of Mexico City has not prevented the metropolis from suffering the problems affecting the rest of the country, namely, inequality and violence. Only in 2023, the city registered a crime incidence of 52,723 reported cases for every 100,000 inhabitants and around 24 percent of the population lived under the poverty line.

We present a study of the night sky brightness around the extended
metropolitan area of Madrid using Sky Quality Meter (SQM) photometers. The map is the first to cover the spatial distribution of the sky brightness in the
center of the Iberian peninsula. These surveys are neccessary to test the light
pollution models that predict night sky brightness as a function of the
location and brightness of the sources of light pollution and the scattering of
light in the atmosphere. We describe the data-retrieval methodology, which
includes an automated procedure to measure from a moving vehicle in order to
speed up the data collection, providing a denser and wider survey than previous
works with similar time frames. We compare the night sky brightness map to the
nocturnal radiance measured from space by the DMSP satellite. We find that i) a
single source model is not enough to explain the radial evolution of the night
sky brightness, despite the predominance of Madrid in size and population, and
ii) that the orography of the region should be taken into account when deriving
geo-specific models from general first-principles models. We show the tight
relationship between these two luminance measures. This finding sets up an
alternative roadmap to extended studies over the globe that will not require
the local deployment of photometers or trained personnel.

In the year 1500, the share of Western Europe's population living in urban areas was just six percent, but this rose to 31 percent by the end of the 19th century. Despite this drastic change, development was quite slow between 1500 and 1800, and it was not until the industrial revolution when there was a spike in urbanization. As Britain was the first region to undergo the industrial revolution, from around the 1760s until the 1840s, these areas were the most urbanized in Europe by 1890. The Low Countries Prior to the 19th century, Belgium and the Netherlands had been the most urbanized regions due to the legacy of their proto-industrial areas in the medieval period, and then the growth of their port cities during the Netherlands' empirical expansion (Belgium was a part of the Netherlands until the 1830s). Belgium was also quick to industrialize in the 1800s, and saw faster development than its larger, more economically powerful neighbors, France and Germany. Least-urban areas Ireland was the only Western European region with virtually no urbanization in the 16th and 17th century, but the industrial growth of Belfast and Dublin (then major port cities of the British Empire) saw this change by the late-1800s. The region of Scandinavia was the least-urbanized area in Western Europe by 1890, but it saw rapid economic growth in Europe during the first half of the following century.

The city of Paris in France had an estimated gross domestic product of 757.6 billion Euros in 2021, the most of any European city. Paris was followed by the spanish capital, Madrid, which had a GDP of 237.5 billion Euros, and the Irish capital, Dublin at 230 billion Euros. Milan, in the prosperous north of Italy, had a GDP of 228.4 billion Euros, 65 billion euros larger than the Italian capital Rome, and was the largest non-capital city in terms of GDP in Europe. The engine of Europe Among European countries, Germany had by far the largest economy, with a gross domestic product of over 4.18 trillion Euros. The United Kingdom or France have been Europe's second largest economy since the 1980s, depending on the year, with forecasts suggesting France will overtake the UK going into the 2020s. Germany however, has been the biggest European economy for some time, with five cities (Munich, Berlin, Hamburg, Stuttgart and Frankfurt) among the 15 largest European cities by GDP. Europe's largest cities In 2023, Moscow was the largest european city, with a population of nearly 12.7 million. Paris was the largest city in western Europe, with a population of over 11 million, while London was Europe's third-largest city at 9.6 million inhabitants.

At the beginning of the Common Era, over three quarters of Western Europe's population lived in the Mediterranean regions that make up present-day France, Greece, Italy, Spain, and Portugal. At this time, all of these areas were under the control of the Roman Empire, and remained so until the fifth century. The Mediterranean region was the center of trade between Europe, Asia, and Africa throughout most of Antiquity and the Middle Ages, and many of the most populous cities in the Europe were located in present-day Italy or Spain during this time. Due to this fact, these metropolitan areas were some of the most severely-hit during pandemic outbreaks. The emergence of Europe's maritime empires during the 16th and 17th centuries, and later the economic growth of Germany, led to a shift in Western Europe's population distribution; yet, over half of the population was located in these Mediterranean countries until the 19th century.
