Spain, second country with most childless women: housing or ideology?

Spain ranks second globally in childless women, behind only Japan, according to data published by El Debate in January 2026. This has reignited the debate on the root causes of low birth rates, highlighting two main analytical schools of thought.

The economic factor: housing and wages

One argument points to real estate speculation and job insecurity as the primary drivers of declining birth rates. The ratio between housing prices and wages in Spain is among the worst in Europe. It is difficult to imagine a young couple considering having children when they spend over 40% of their income on rent. This is not just a Spanish issue: Japan has faced a similar crisis for decades, with a lost generation unable to achieve independence. The high cost of living, lack of stability, and rising basic services costs complete the picture.

The cultural current: feminism, hypergamy, and values

Opposing the economic explanation, another narrative points to cultural and behavioral changes. Factors such as social engineering, hegemonic feminism, and female hypergamy are cited as responsible. According to this view, women with higher education and career aspirations delay or forgo motherhood entirely. The search for partners meeting increasingly demanding standards—the 'Fast Family Plan'—combined with career and leisure priorities, explains why childlessness persists even in economically stable contexts. Data from Spain and Japan, two of the most educated and technified societies, seem to support this thesis.

Immigration and demographic future

The debate extends beyond causes to consequences. If native birth rates continue to fall, generational replacement will depend on immigration. It is already noted that populations of African and Latin American origin maintain higher fertility, which will transform the country's demographic profile in the coming decades. Some see this as a natural solution; others view it as a threat to national identity.



The data is stubborn: Spain and Japan lead a phenomenon no developed country has successfully reversed with incentive policies. The lingering question is whether the problem lies in the wallet or the mind. Or perhaps both.
