Key Facts & Findings
- Uruguay’s population reached approximately 3.44 million at its most recent census, with 16.3 percent of the population aged 65 or older as of 2025 estimates, more than double the 8.2 percent recorded in 1950.
- Uruguay’s total fertility rate has fallen to between 1.19 and 1.41 children per woman, well below the replacement level of roughly 2.1.
- Nearly 60 percent of Uruguay’s population lives in the Montevideo metropolitan area, and over 95 percent lives in urban areas nationally.
- Uruguay’s total dependency ratio stands at roughly 52 percent, with elderly dependency now approaching or exceeding youth dependency, a structural crossover distinct from most of Latin America.
- Uruguay’s population is projected to have peaked around 2020 and could decline to approximately 3 million by 2070, a loss of roughly 510,000 people.
- Net migration has been slightly negative in recent years, meaning immigration has not offset Uruguay’s fertility-driven aging.
Uruguay’s population reached about 3.44 million at its most recent census, and the country’s population is projected to have already peaked, around 2020 before beginning a gradual decline that could bring it to roughly 3 million by 2070, a loss of some 510,000 people over five decades. Fertility has fallen to just 1.19 to 1.41 children per woman depending on the estimate, over 95 percent of the population is urban, and nearly 60 percent lives in the Montevideo metropolitan area alone.
Uruguay entered its demographic transition decades before most of its Latin American neighbors, and it is now confronting the consequences: a shrinking working-age base, a rising elderly dependency burden, and a population small enough that even modest absolute changes carry outsized proportional weight.
Uruguay’s Population Is Among Latin America’s Older Populations
Uruguay’s age structure already looks distinctly different from the regional norm. As of 2025 estimates, 17.9 percent of the population was under 15, 65.8 percent was of working age, and 16.3 percent was 65 or older, an elderly share considerably higher than most of Latin America and closer to levels seen in parts of aging Southern Europe.
Uruguay’s median age has been variously estimated between 36.4 and 39.1 years depending on the source and year, but every recent estimate places it among the two or three oldest populations in the Americas outside North America, alongside Chile.
How Uruguay Became an Aging Society
Uruguay’s early demographic transition traces back further than most of its neighbors. The country began urbanizing and industrializing relatively early in the twentieth century, developed a comparatively extensive welfare state, and saw fertility decline start decades before it did in most of Latin America.
That head start means Uruguay’s population age structure has been evolving gradually for nearly a century rather than compressing into a few rapid decades, as has happened more recently in countries like Colombia. The historical data illustrates the trajectory clearly.
Uruguay Age Structure Over Time
| Year | Population | 0-14 Share | 15-64 Share | 65+ Share |
|---|---|---|---|---|
| 1950 | 2,239,000 | 27.9% | 63.9% | 8.2% |
| 1980 | 2,916,000 | 26.9% | 62.7% | 10.4% |
| 2015 | ~3.4 million | 21.4% | 64.2% | 14.4% |
| 2025 (est.) | ~3.4 million | 17.9% | 65.8% | 16.3% |
Fertility Is Reshaping the Population Pyramid
Uruguay’s total fertility rate sits somewhere between 1.19 and 1.41 children per woman depending on the estimate and year, well below the replacement level of roughly 2.1 in either case. That places Uruguay among the lowest-fertility countries in Latin America alongside Chile, Colombia and Cuba. The consequence is visible directly in the population pyramid: each successive birth cohort is smaller than the one before it, meaning the base of Uruguay’s age structure has been narrowing for years even as the older cohorts born during higher-fertility decades continue aging upward through the pyramid.
Longer Life Expectancy Is Expanding Older Age Groups
Uruguay’s life expectancy, around 78 to 79 years overall, with women outliving men by roughly six to seven years, has climbed steadily over recent decades, adding to the older population from the opposite direction. Combined with low fertility, this longevity gain is precisely the mechanism that produces population aging: fewer people entering the population at the bottom, more people staying in it longer at the top.
Uruguay’s Geographic Aging Pattern
Uruguay’s extreme urbanization, over 95 percent of the population lives in urban areas, concentrates its demographic dynamics heavily around Montevideo, which alone holds close to 60 percent of the national population in its metropolitan area.
Interior departments, more agricultural and less urbanized than the capital region, have generally shown slower population growth and, in several cases, more pronounced aging as younger residents move toward Montevideo or emigrate abroad, leaving behind an interior population skewed older than the national average.
Aging and the Labor Force
Uruguay’s dependency ratio, the number of children and elderly people relative to the working-age population, stood at roughly 51.9 to 52.3 percent as of recent estimates, meaning each working-age Uruguayan supports, on average, close to half a dependent. Within that total, the elderly dependency component, around 24.7 percent, has grown to roughly match or exceed the youth dependency component, a crossover that marks a structurally different kind of dependency burden than the child-heavy dependency ratios still typical of younger Latin American countries.
Uruguay is currently passing through what demographers describe as a temporary demographic dividend window, extending to roughly 2035, characterized by relatively low school-age dependency even as elderly dependency climbs, a window analysts have suggested could be used to reallocate public resources toward improving educational quality before the balance shifts further toward elder-care spending.
Pensions, Healthcare and Caregiving
A rising elderly population share puts direct pressure on Uruguay’s pension system, built around a combination of pay-as-you-go and individual savings components, since a shrinking working-age base relative to retirees strains the pay-as-you-go portion’s underlying arithmetic. Healthcare spending faces similar pressure as demand shifts toward chronic disease management and long-term care associated with an aging population.
Family caregiving capacity, historically a significant source of elder support, is constrained by Uruguay’s low fertility, since smaller families mean fewer adult children are available on average to share caregiving responsibilities for aging parents, a dynamic increasingly discussed among Uruguayan policymakers alongside proposals to raise the retirement age, incentivize skilled immigration, invest in childcare to support desired fertility, and encourage productivity-boosting technological adoption to offset a shrinking workforce.
Can Migration Offset Population Aging?
Uruguay’s net migration rate has been slightly negative in recent estimates, meaning more people currently leave the country than arrive, the opposite direction from what would be needed to meaningfully offset population aging through immigration. Immigrant share of the population stood at roughly 4.7 percent as of 2024, a modest figure that has not been sufficient to counterbalance
Uruguay’s low fertility and rising elderly population. Some policy proposals specifically call for actively incentivizing skilled immigration as one lever for addressing the shrinking workforce, but migration at the scale needed to meaningfully offset Uruguay’s demographic trajectory would require a substantial and sustained policy shift from the recent pattern of modest net outflow.
Uruguay’s Long-Term Population Outlook
Projections summarized by regional press coverage of Uruguay’s demographic trajectory suggest the population, having peaked around 2020, will decline gradually over the coming decades, potentially losing around 510,000 people over fifty years and reaching approximately 3 million by 2070. That trajectory would make Uruguay one of the earlier Latin American countries, alongside Chile, to move from population growth into sustained decline, a milestone most of the region’s larger countries remain considerably further from reaching.
These projections, like all long-range demographic forecasts, depend on fertility, mortality and migration trends continuing on their current paths, and meaningful policy shifts, particularly around immigration or fertility support, could alter the trajectory, though reversing decades of accumulated low fertility tends to happen slowly even when policy changes are enacted.
Conclusion
Uruguay’s demographic profile today is the product of a transition that began earlier and has run longer than almost anywhere else in Latin America. Low fertility, rising longevity and heavy urban concentration around Montevideo have combined to produce a population that has already likely peaked and is expected to shrink gradually over the coming half-century.
For a country of Uruguay’s modest size, the practical consequences- pension sustainability, healthcare capacity, and a shrinking working-age base- are not distant hypotheticals but present-tense policy questions the country is already navigating, several years ahead of most of its regional neighbors.
Frequently Asked Questions
1. Why is Uruguay’s population aging?
A combination of very low fertility, between 1.19 and 1.41 children per woman depending on the estimate, and rising life expectancy of around 78 to 79 years has steadily increased Uruguay’s elderly population share, from 8.2 percent in 1950 to 16.3 percent by 2025.
2. Does Uruguay have a shrinking population?
Uruguay’s population is projected to have peaked around 2020 and to decline gradually thereafter, potentially reaching approximately 3 million by 2070, though current census-based population figures remain close to 3.4 million.
3. Can immigration reduce Uruguay’s aging pressure?
Immigration could in principle help offset population aging, but Uruguay’s recent net migration rate has been slightly negative, meaning more people currently leave than arrive, the opposite of what would be needed, though some policymakers have proposed actively incentivizing skilled immigration as a partial solution.
4. What is Uruguay’s current fertility rate?
Estimates place Uruguay’s total fertility rate between 1.19 and 1.41 children per woman depending on the source and year, well below the replacement level of approximately 2.1.
5. How does Uruguay’s aging compare with the rest of Latin America?
Uruguay is among the two or three most aged populations in Latin America, comparable to Chile, and considerably further along in its demographic transition than Colombia, Brazil, Argentina and most of the rest of the region.
6. What is Uruguay’s dependency ratio?
Uruguay’s total dependency ratio is approximately 52 percent, meaning each working-age person supports roughly half a dependent on average, with elderly dependency now approaching or exceeding youth dependency.
7. How urban is Uruguay?
Uruguay is over 95 percent urban, with close to 60 percent of the national population living within the Montevideo metropolitan area alone.
8. What is Uruguay doing to address population aging?
Proposed and discussed policy responses include raising the retirement age, incentivizing skilled immigration, investing in childcare to support fertility, and encouraging productivity-enhancing technology adoption to offset a shrinking workforce, though implementation and impact vary.
9. Is Uruguay’s population decline unique in Latin America?
No, but Uruguay is ahead of most of the region. Chile shows a broadly similar trajectory toward an early population peak and decline, while most other Latin American countries remain years to decades behind in their demographic transitions.
10. What does a temporary demographic dividend mean for Uruguay?
Uruguay is currently in a window, extending to roughly 2035, of relatively low school-age dependency even as elderly dependency rises, an opportunity some analysts suggest could be used to reallocate public resources toward improving educational quality before the dependency balance shifts further toward elder care.
