Population development
Between 1999 and 2009, Spain's population increased very strongly, both compared to other European countries and compared to the decades before. For example, Spain's population increased by 1.1 million in the 1990s and by 7 million in the first decade of the 21st century. Much of the population growth was due to immigration. For example, the foreign population increased from 0.74 million in 1999 to 5.73 million in 2011. It should still be noted that there were also naturalizations. The fertility rate in Spain in 2016 was around 1.34 children per woman, below the EU average of 1.60. In 2016, the average age in Spain was 43.1 years.

Life expectancy
The average life expectancy of Spaniards was found to be 82.5 years in 2012, the highest in the European Union, ahead of Italy (82.4) and France (82.1). Accordingly, the average life expectancy for men was 79.5 years and for women 85.5 years. In 2007, 16.7 percent of the population was older than 65. Due to the high life expectancy in combination with the low fertility, it is assumed that Spain will become one of the oldest societies in the world in the future.

Languages
→ Main article: Languages in Spain
Spanish, Catalan, Galician and Basque are the main languages spoken in Spain. Spanish is the official language throughout the national territory. Catalan is also an official language (lenguas co-oficiales) in the autonomous communities of Catalonia, Valencia (where it is known as Valencian) and the Balearic Islands, Basque in the Basque Country and parts of Navarre, and Galician in Galicia. In the Val d'Aran, Aranese, a variety of Gascon, has official status.
The country name Kingdom of Spain in the regional languages is Galician Reino de España, Catalan Regne d'Espanya, Asturian Reinu d'España, Basque Espainiako Erresuma, Aranese Reialme d'Espanha and Aragonese Reino d'Espanya.
In addition, there are some languages that are only spoken by a small number of people and do not have the status of an official language. Among these are Asturleonesian and Aragonese. In the Jálama Valley (Cáceres province) near the Portuguese border, A Fala, a dialect of the Galician-Portuguese language, is spoken. In Melilla, the Masirian minority also speaks Tamazight.
During the holiday season, seasonal workers from Germany and Poland also work in the tourist regions, as well as South Americans in many cases. In some tourist regions, such as the Costa Blanca or the Costa del Sol, a comparatively large number of Germans and Englishmen are permanent residents.
The foreign languages spoken are mostly English and French. Younger Spaniards mostly speak English as a foreign language, older ones rather French. Among the general population, however, applicable foreign language skills are still not the rule. According to a survey conducted by Eurostat in 2011, 49% of adult Spaniards (aged 25-64) self-assess that they do not speak a foreign language. In contrast, in 2011, the percentage of primary school students learning a foreign language, usually English, was already 99% and in upper secondary 97%, with 22% also learning a second foreign language, mainly French due to its geographical proximity to France. In areas popular with tourists, particularly the Mediterranean and the Balearic Islands, English and German are sometimes used.
In Catalonia, most schools and universities teach in Catalan, but Spanish may be used by all students in classes and exams.
Minorities
Among the country's minorities are above all the "Gitanos" (Spanish Roma), who immigrated to Spain around the 16th century. Today, there are about 600,000 to 800,000 Gitanos living in Spain. The Spanish Roma are mainly located in big cities like Madrid, Barcelona, Valencia or Sevilla. They have produced some world-famous stars, such as the singer Camarón de la Isla or the football player José Antonio Reyes. Especially in the Spanish music scene, especially the flamenco, many Roma can be found.

For a long time, Spain had only low immigration figures. It was not until the late 1980s that Spain became the main destination for Latin American emigration. This has led to a sharp rise in immigration to a population increase of over five million inhabitants. In 2007, there were close to 1.8 million people with a Latin American migrant background in Spain (Tedesco, 2008: 3). The number of foreigners living in Spain is around 5 million (January 2019), which is twelve per cent of the total population; of these, just over 2 million are citizens of other EU countries. Compared to the rest of the EU, Spain ranks second in absolute numbers behind Germany (7.1 million). Looking at the proportion of citizens of other countries, Spain ranks fifth behind Luxembourg (43.0%), Latvia (17.4%), Cyprus and Estonia (both 15.9%). Among Member States with more than three million inhabitants, Spain's non-national rate of 12.3% is the highest, followed by Austria (10.5%), Belgium (9.7%) and Germany (8.7%). Most immigrants come from Romania, the Maghreb countries or Latin America, as well as from the United Kingdom and Germany, for whom Spain is a popular retirement destination. Between 2003 and 2017, a total of 1,446,315 people acquired Spanish nationality.
Spaniards abroad
The number of Spanish citizens living abroad is around 2.6 million (January 2020), 1,576,350 of them in America and 945,027 in Europe. While only 20.6 percent of Spaniards living in America were born in Spain, this percentage is 49.7 percent for those residing in another European country. This is partly because the major waves of emigration from the mid-19th century until the Spanish Civil War were mostly to South and Central America, particularly Argentina, Venezuela, Mexico, Uruguay, and Cuba, while with the Plan de Estabilización (1959) there was a wave of emigration to European countries such as France, Germany, Switzerland, Belgium, and the United Kingdom that lasted until 1972. In addition, many immigrants from South American countries, who had in the meantime acquired Spanish nationality, left Spain in the wake of the euro crisis and returned to their home countries.
Religions and world views
Although 92 percent of the population (as of 2000) officially belonged to the Roman CatholicChurch, the number of those who actively participate in religious life is declining. In a study conducted by the state polling institute Centro de Investigaciones Sociológicas in 2015, 68 percent of respondents still said they were Catholics. The Catholic Church is financed by the Spanish state on the basis of a treaty with the Holy See and not from church taxes paid directly by its members, which is why leaving the church brings no financial benefits. Since 2007, however, taxpayers have had to decide for themselves whether 0.7% of their income tax should go to church or other social or cultural purposes. If they do not make a decision, this obligatory tax amount is directly allocated to the other purposes. Direct state funding, which had existed since 1979, has been completely abolished. Between 1988 and 2007, taxpayers could decide whether 0.5% of their income tax should go to church or other purposes. However, at that time, if the amount fell short of a minimum amount, the state paid for it. In 2008, in 7,195,155 (34.31%) tax returns, this 0.7% was donated to the Catholic Church. Two years earlier, it had been about 711,975 less. The income from taxes thus rose from 173.8 million euros to 252.7 million euros since the new regulation of 2007.
It is not readily possible for Spain's Catholics to officially renounce the Church, since Spanish law does not recognize the act of leaving the Church, and Spain's Catholic Church was relieved by the highest court of the obligation to erase the data of its members from the church records at their request. This decision by the highest court in Spain came about, among other things, because "the Archbishopric of Valencia, which is considered particularly conservative, refused to carry out erasures of any form". The archdiocese had not been impressed by the instructions of the Spanish data protection authority (AEPD) and had initiated numerous legal proceedings, losing 171 cases before the decision of the Supreme Court.
A larger minority of 15.9% of the population describes itself as non-religious and 9.5% as atheist, according to the aforementioned study. According to a study by the Pew Research Center, 46% of Spaniards describe themselves as "religious" and 19% as "very religious". Among 18-39 year olds, only a minority of 9% are very religious; in the world, the figure is only lower in France and Japan, where, moreover, the figures for 39-59 year olds are only marginally higher. According to a representative survey by Eurobarometer, 59% of people in Spain believed in God in 2005, with a further 21% believing in some other spiritual force. 18 % percent of the respondents believed neither in a God nor in another spiritual force, 2 % of the respondents were undecided.
Muslims make up 4.13% (as of the end of 2016), Protestants 0.3% and Jehovah's Witnesses 0.25% of the population. Spain is home to the important pilgrimage site of Santiago de Compostela, the destination of many pilgrims on the Way of St. James.

Largest cities
→ Main article: List of cities in Spain
Spain has two cities with over a million inhabitants, Madrid and Barcelona. However, the strong growth of the cities in recent years has led to the emergence of metropolitan regions, some of which extend far beyond the political-administrative boundaries of the municipalities. The metropolitan areas of Madrid and Barcelona are home to over six and four million people respectively, while the metropolitan regions of Valencia, Seville and Bilbao each have over one million inhabitants.

Autonomous Communities by population
The total of 17 autonomous communities are very heterogeneous in size. While the populations of Andalusia, Catalonia, the Autonomous Community of Madrid and the Valencia region range from around 5 to 9 million, the smallest regions of Navarre, Cantabria and La Rioja are home to well under one million people.
