1. Over 15% of Spain's Population Was Born Abroad
More than 15% of Spain's population was born outside the country, with a significant portion originating from beyond Europe, particularly from Spain's former colonies across Latin America. This places Spain as the 4th largest immigrant-receiving country in Europe and the 10th globally. Throughout the 20th century, from 1900 to 2000, while Spain's overall population nearly doubled, its rural population experienced a notable decline. In recent years, Spain's population growth has stagnated.
Between 2011 and 2021, the national population grew by a mere 0.12%, marking the lowest growth rate recorded in Spain since record-keeping began between 1833 and 1846. This is largely attributed to Spain's extremely low birth rate, prompting criticism of the government's support policies. Among Western European nations, Spain allocates the smallest portion of its national budget to assist struggling families, limited to just 0.5% of GDP. Consequently, many Spaniards have chosen to emigrate abroad in search of better living standards rather than remaining in their homeland.


2. Imbalance in Infrastructure Investment and Basic Amenities
In 1970, during Turewell's first industrialization program, tens of thousands migrated in search of better job opportunities. This exodus left behind small villages with harsh living conditions, particularly cold winters in high-altitude areas, minimal social amenities, and insufficient infrastructure investment. Additionally, the remaining 40% of the population in these sparsely populated regions face challenges such as limited internet access and a single, notoriously slow train that travels at just 30 km/h. This situation gained attention on Spanish social media, where a video mocked the train's sluggish pace by showing a tractor overtaking it. This starkly contrasts with Spain's developed regions like Madrid, a major European tech hub with high-speed rail networks operating ten times faster than the slow train, highlighting the country's vast wealth disparity.
Due to this chaos and lack of infrastructure investment, rural areas in Spain have become less attractive for living, prompting residents to leave and deterring potential investors. This creates a vicious cycle, with the Spanish government making little progress in reversing the trend over decades. As a result, 90% of Spain's population now resides within just 30% of the land area, while the remaining 10% are scattered across the remaining 70% of the country.


3. The Geographical Structure of Spain
Spain is a country characterized by numerous mountain ranges and holds the highest average elevation among European Union nations. Its terrain can be divided into three main regions: the central Meseta plateau, other mountainous areas, and lowland zones. The Meseta, a vast central plateau, dominates the heart of Spain with an average elevation ranging from 610 to 700 meters. Surrounded by mountains, the Meseta slopes gently westward, where rivers flow into Portugal.
The Central System mountain range acts as the backbone of the region, dividing the Meseta into northern and southern sections. Additionally, the Cantabrian Mountains in the northwest and the Pyrenees along the French border create a rugged landscape that isolates the southeast from the rest of Western Europe. Due to the challenging terrain, only a few small villages and towns exist, often requiring over 45 minutes of driving to travel between them. The predominantly mountainous geography has resulted in underdeveloped and outdated transportation infrastructure, with no high-speed rail connections like those found in central regions. Consequently, the population is sparse, with most residents concentrated in major cities around the central areas and along the Mediterranean and Atlantic coasts in the south and north.


4. The Spanish Civil War
Spain endured numerous civil wars and uprisings, driven by conflicts between reformist and conservative factions vying for control. Reformists sought to dismantle the entrenched absolute monarchy and establish a new state model, while conservatives aimed to thwart these changes and preserve the monarchy. Supporters of the Carlist movement, rallying under the motto "God, Country, King," fought to uphold Spain's traditional absolutism and Catholic faith, opposing liberalism and, later, the republicanism of the Spanish government at the time.
The war stemmed from long-standing tensions and historical grievances. Spain experienced multiple regimes following the Napoleonic Wars in the early 19th century. The reign of King Alfonso XIII lasted from 1887 to 1924, succeeded by the military dictatorship of Primo de Rivera. By 1928, this regime gave way to a brief two-year monarchy, until the Second Republic was established in 1931. The republic was led by a coalition of leftist and centrist parties.
They implemented controversial reforms, such as the 1932 Land Law, which redistributed agricultural land to impoverished farmers. Millions of Spaniards lived in extreme poverty under the harsh rule of landowning elites in a quasi-feudal system. These reforms, alongside anti-clerical measures, the expulsion of Muslims, and military cutbacks, provoked fierce opposition from the old ruling class. Spain continued to function as a right-wing authoritarian state for decades. The prolonged history of civil war and centralized policies over the past 50 years led to a 28% population decline in Spain's rural areas.


5. Spain Did Not Join the United Nations Until 1955 and the European Economic Community Until 1986
Spain did not become a member of the United Nations until 1955 and refrained from joining the European Economic Community, the precursor to the European Union, until 1986. Initially, the country established independent political parties and domestic trade unions during a period when the dictatorship had banned such activities, pursuing an Otarchi-style economic policy. This decision left Spain grappling with the widespread devastation from its civil war, and its economy remained stagnant for decades. This situation triggered a massive emigration wave, as those opposed to the regime or facing economic hardships left the country, resulting in decades of net migration out of Spain.
Free-market policies and industrial reforms transformed the once stagnant and archaic Spanish economy, revitalizing it with substantial foreign investments. Industrial zones around the Basque Country, the northern coast of Barcelona, and Madrid boomed with job opportunities and development prospects, attracting millions of young Spaniards from rural areas. This shift led to significant internal migration and urbanization.
