Demographic Shifts and Social Vulnerability: A Deep Dive into 21st-Century Challenges
A recent discussion, “Demography and Vulnerability in the 21st century: global risk map,” explored how accelerating population changes are driving new forms of social exclusion and vulnerability worldwide. The event, moderated by journalist Sergio C. Fanjul, featured insights from leading experts in economics, social policy, and ethics.
The “Reproductive Revolution” and Changing Family Structures
Historically, demographic concerns centered on overpopulation. However, Diego Ramiro Farinas, director of the Institute of Economics, Geography and Demography of the CSIC, highlighted a significant shift: much of the world is now experiencing fertility rates below replacement level. In Spain, the fertility rate has fallen to an average of 1.19 children per woman, comparable to South Korea, which has the lowest rate globally.
Farinas termed this trend a “reproductive revolution,” noting the dramatic changes in family size and structure. Even as early 20th-century Spanish families averaged 4.5 children with high infant mortality, today Europe boasts the highest life expectancy, resulting in an unprecedented number of coexisting generations. This creates new vulnerabilities, with an increasing proportion of couples potentially reaching old age without children, leading to narrower family networks and increased caregiving burdens for the elderly.
Pillars of Social Coexistence and Addressing Vulnerabilities
Experts emphasized the need for a systemic approach to address these growing vulnerabilities. Carlos Susias, president of the EAPN – European Anti Poverty Network, outlined six fundamental pillars for equitable coexistence:
- Decent income for families (through salaries and pensions)
- An accessible and universal healthcare system, with a focus on primary care
- An educational system capable of managing diversity
- Social services extending beyond dependency care
- Effective housing policies
- Progressive fiscal policies
Susias was particularly critical of current housing policies in Spain, stating they have become a “factor of exclusion” for both native and migrant populations.
Ethical Considerations: Distributive Justice and Intergenerational Equity
Fatima Alvarez, a philosopher specializing in critical thinking and applied ethics, underscored the ethical dimensions of these demographic shifts. She lamented a growing sense of individualism and the erosion of community. Alvarez argued that, in scenarios of potential resource scarcity, ethics demands a rethinking of “distributive justice and justice between generations.” She advocated for positive discrimination measures to ensure equity for those starting at a disadvantage, stating, “To be able to mitigate inequalities sometimes you have to be unequal, guaranteeing opportunities to those who start out at a disadvantage.”
Debunking the “Generational Battle” and Supporting Youth
The experts refuted the notion of a “war” between young people and adults. Ramiro pointed out that declining birth rates and delayed emancipation are rooted in structural problems, citing the 2008 financial crisis as an example, where unemployment significantly reduced fertility rates. Alvarez added that a lack of real conciliation policies and the professional penalties faced by mothers contribute to the issue.
Susias encouraged young people to advocate for their rights, emphasizing the need for decent wages and affordable housing. He called for public housing as a public service, rather than focusing on subsidies for homeowners.
Migration as a Driver of Sustainability
The discussion also addressed migration, with experts challenging common stereotypes. Susias highlighted that Spain relies on migration to maintain its social security system, estimating that without it, the country would need an additional 300,000 to 400,000 births to sustain its current trajectory. He also debunked the myth that migrants are primarily drawn by social welfare, noting that regions with robust social protections do not necessarily have higher immigration rates.
Alvarez appealed to a sense of shared history, reminding participants that “we have been a migrant people” and emphasizing our interdependence. She urged for creating spaces for interaction to combat xenophobia and foster understanding. Ramiro warned that Spain is already competing globally to attract migratory flows, particularly in sectors like elder care and agriculture.
The vulnerability of rural areas was also discussed, with Susias emphasizing the need for both employment opportunities and a high quality of life to prevent depopulation.
Active Realism and a Call to Action
Despite the challenges, the event concluded with a call for “active realism.” Ramiro emphasized the gains made in life expectancy and education. Susias encouraged young people to engage politically and fight for their rights, acknowledging that the future may differ from the ideals of previous generations. Alvarez championed the “mixture of people to understand each other.”
Sergio C. Fanjul closed the event with a quote from Jane Goodall: “One way to help the world is to improve the lives of the people who live in it so that they can be part of the effort to protect it.”
