The global economy is going through a structural inflection point driven by two simultaneous demographic trends: accelerated population ageing in developed and emerging economies, and tightening migration policies in multiple regions.
This article analyzes the economic implications of both phenomena, focusing on two critical dimensions: the supply of labor and the transformation of the consumption profile.
Based on empirical evidence and institutional projections (IMF, OECD, UN), it is argued that aging will reduce the active labor force and reconfigure demand towards care-intensive goods and services, while migration, although it is a potential source of productive compensation and diversity in consumption, faces institutional barriers that limit its countercyclical effect.
In the new global economic landscape, characterized by geopolitical tensions, technological transition, and growing fiscal pressure, the strategic management of migration policy and the redesign of social protection systems are imperative to sustain productivity, social cohesion, and inclusive growth.
I. Population Aging: A Silent Threat to the Labor Supply
1.1. Reduction of the working-age population
Demographic ageing is a global phenomenon that particularly affects developed economies.?According to the International Monetary Fund (IMF), the population aged 65 and over is increasing rapidly worldwide, due to declining fertility rates and increasing life expectancy.?This demographic shift implies a reduction in the working-age population, which can limit economic growth.
1.2. Impact on productivity and economic growth
The decline in the labor force can be partially offset by increases in productivity.?However, according to a United Nations report, to sustain per capita income growth of 2% per year over the next 50 years, countries like Japan will need labor productivity growth of 2.6% per year, which represents a considerable challenge.
II. Migration and restrictive policies: contrasting effects on the global economy
2.1. Migration as a source of economic dynamism
International migration has historically been a source of economic dynamism for host countries.?Immigrants are typically younger and have higher labor participation rates than the native-born population.?In addition, they contribute to economic growth and public finances.?For example, the Bank of Spain has pointed out that migratory flows have been one of the factors that have allowed the Spanish economy to outperform its European peers.?In addition, immigration is estimated to have contributed significantly to the increase in GDP per capita in the period 2022-2024.
2.2. Restrictive migration policies and their economic consequences
Restrictive migration policies can have negative effects on the economy.?In the United States, mass deportations could reduce GDP by 4.2% to 6.8%, and lead to a drastic increase in prices, especially in the agricultural sector, due to declining production and rising food costs.
III. Implications on the supply of labour
3.1. Ageing and shortage of workers
An aging population leads to a shortage of workers in key sectors.?For example, in Europe, the dependency ratio of older people is expected to increase from 34% in 2019 to 57% in 2050, implying a greater burden on the working population.
3.2. Migration as a solution to labour shortages
Migration can help mitigate labor shortages.?Immigrants often hold jobs in sectors with a shortage of workers, such as agriculture, construction, and services.?In addition, their presence can help to maintain balance in social security systems by increasing the proportion of active workers.
IV. Transformations in the consumption profile
4.1. Changes in consumption patterns due to ageing
The aging of the 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 report by Capgemini, 45% of older consumers anticipate increasing their spending on lifestyle improvements, such as travel, luxury goods, and home improvements.
4.2. Migration-driven diversification of consumption
Migration also influences consumption patterns, as immigrants introduce new preferences and demands into the markets of receiving countries.?This can lead to greater diversity in product and service offerings, and the expansion of specific niche markets.
Conclusion
Population ageing and migration dynamics are structural forces that are transforming the global economy.?Ageing poses significant challenges to labour supply and economic growth, while migration can offer solutions, provided it is properly managed.?In addition, both phenomena are redefining consumption patterns, requiring adaptations by companies and policymakers.?Addressing these challenges in a comprehensive and coordinated manner will be essential to ensure sustainable and inclusive economic growth in the future.
