Demographics and Borders: How Aging and Migration Are Redrawing the New Global Economic Framework

The global economy is undergoing a structural turning point driven by two simultaneous demographic trends: the rapid aging of the population in both developed and emerging economies, and the tightening of migration policies across multiple regions.

This article analyzes the economic implications of both phenomena, focusing on two critical dimensions: labor supply and the transformation of consumption profiles.

Based on empirical evidence and institutional projections (IMF, OECD, UN), it is argued that aging will reduce the active labor force and shift demand toward care-intensive goods and services. While migration could act as a potential source of productive compensation and consumption diversity, institutional barriers limit its countercyclical effect.

In the new global economic framework—characterized by geopolitical tensions, technological transition, and growing fiscal pressure—strategic migration policy management and the redesign of social protection systems are imperative to sustain productivity, social cohesion, and inclusive growth.

I. Population Aging: A Silent Threat to Labor Supply

1.1. Decline in the Working-Age Population
Demographic aging is a global phenomenon, particularly affecting developed economies. According to the International Monetary Fund (IMF), the population aged 65 and older is rapidly increasing worldwide due to declining fertility rates and rising life expectancy. This demographic shift implies a reduction in the working-age population, which could limit economic growth.

1.2. Impact on Productivity and Economic Growth
The decline in the labor force can be partially offset by productivity gains. However, according to a United Nations report, in order to maintain a 2% annual growth in per capita income over the next 50 years, countries like Japan would need labor productivity to grow by 2.6% annually—an extremely challenging goal.

II. Migration and Restrictive Policies: Contrasting Effects on the Global Economy

2.1. Migration as a Source of Economic Dynamism
International migration has historically served as a source of economic dynamism for host countries. Migrants tend to be younger and have higher labor force participation rates than the native population. They also contribute to economic growth and public finances. For example, the Bank of Spain has pointed out that migration flows have been one of the factors enabling the Spanish economy to outperform its European peers. It is estimated that immigration significantly contributed to the increase in per capita GDP between 2022 and 2024.

2.2. Restrictive Migration Policies and Their Economic Consequences
Restrictive migration policies can have negative economic effects. In the United States, mass deportations could reduce GDP by between 4.2% and 6.8%, and cause a drastic rise in prices—particularly in the agricultural sector—due to decreased production and increased food costs.

III. Implications for the Labor Supply

3.1. Aging and Labor Shortages
Population aging leads to labor shortages in key sectors. For instance, in Europe, the old-age dependency ratio is expected to rise from 34% in 2019 to 57% in 2050, placing a greater burden on the working population.

3.2. Migration as a Solution to Labor Shortages
Migration can help mitigate labor shortages. Migrants often take jobs in sectors facing worker deficits, such as agriculture, construction, and services. Their presence also contributes to the sustainability of social security systems by increasing the share of active workers.

IV. Shifts in Consumption Patterns

4.1. Consumption Changes Due to Aging
An aging population also affects consumption patterns. Older consumers tend to spend more on health, wellness, and services, and less on durable goods. For example, according to a Capgemini report, 45% of older consumers plan to increase their spending on lifestyle enhancements such as travel, luxury goods, and home renovations.

4.2. Consumption Diversification Driven by Migration
Migration also influences consumption patterns, as immigrants introduce new preferences and demands into host country markets. This can lead to greater diversity in the supply of products and services and the expansion of niche markets.

Conclusion
Population aging and migration dynamics are structural forces transforming the global economy. Aging presents major challenges for labor supply and economic growth, while migration can offer solutions—provided it is effectively managed. Additionally, both phenomena are reshaping consumption patterns, requiring adaptations from businesses and policymakers alike. Addressing these challenges comprehensively and in a coordinated manner will be essential to ensure sustainable and inclusive economic growth in the future.
