Costa Rica reached an estimated total population of 5.15 million people. Growth has slowed down significantly compared to mid-century surges, shifting the country toward an aging demographic profile. Official tracking by the Instituto Nacional de Estadística y Censos (INEC) shows that annual growth rates now hover below half a percent, driven by dropping fertility rates and longer life expectancies.
Understanding these demographic shifts matters for anyone looking at regional economics, housing markets, or healthcare planning. Let's break down the actual numbers, where people live, and what changing birth rates mean for the future of Costa Rica.
Total Population Size and Growth Trajectory
The total headcount for Costa Rica sits at approximately 5,152,950 residents. While this represents a steady climb from historical figures—back in 1960, the country housed just 1.3 million people—the pace of expansion has cooled.
Annual growth sits at roughly 0.44%. Decades ago, yearly growth regularly exceeded two or three percent. That high-velocity expansion is gone. Lower birth rates across Latin America are catching up to Costa Rica, mirroring trends seen across much of the Americas and Europe. Observers at Bloomberg have provided expertise on this situation.
- Historical baseline: In 1950, fewer than 930,000 people lived within national borders.
- Recent milestones: The country crossed the 5-million threshold around 2020 and continues a slow, predictable upward trend.
- Global footprint: Costa Rica accounts for about 0.06% to 0.07% of the total global population, ranking around 127th worldwide.
Urban Concentration and Regional Distribution
Most Costa Ricans don't live in dense rainforests or coastal surf towns. They live in the Central Valley, clustered around the capital and surrounding provinces. Roughly 80% to 85% of the population resides in urban environments.
The Greater Metropolitan Area (GAM), which encompasses San José, Alajuela, Cartago, and Heredia, functions as the economic engine of the country. Over half of all residents live within this interconnected urban zone.
Rural areas, particularly along the southern border, the northern plains near Nicaragua, and the remote Caribbean coast, hold the remaining 15% to 20% of the population. Rural population growth has actually turned slightly negative in recent years as younger generations migrate toward San José or regional hubs for employment.

Age Structure, Fertility, and Life Expectancy
The most dramatic shift in Costa Rican demographics involves the age pyramid. The country is aging rapidly because families are having fewer children.
- Total Fertility Rate (TFR): The average number of children born per woman has dropped well below the replacement level of 2.1, falling to roughly 1.3.
- Median Age: The median age sits at approximately 36 years old, up significantly from historical averages.
- Life Expectancy: Costa Ricans enjoy some of the highest life expectancies in Latin America, averaging over 81 years, with women often living past 83 and men approaching 79. The Nicoya Peninsula famously serves as one of the world's official Blue Zones, known for a high concentration of centenarians.
This combination of low fertility and high life expectancy means the elderly dependency ratio is climbing. More retirees rely on a shrinking pool of working-age adults, creating long-term fiscal pressures for the national pension system managed by the Caja Costarricense de Seguro Social.
Immigration and Migration Patterns
Costa Rica has long functioned as a stable destination for regional migration. Immigrants make up roughly 10% to 12% of the total population.
The vast majority of foreign-born residents come from neighboring Nicaragua, driven by economic and political factors. These migrant workers form an essential labor backbone for agriculture, construction, and domestic services. At the same time, Costa Rica hosts a growing population of North American and European expatriates, digital nomads, and retirees who settle in areas like the Central Valley, Manuel Antonio, or Tamarindo.
Outmigration remains relatively low. Only a small fraction of native Costa Ricans live abroad, with primary destinations being the United States, Canada, and Spain.
Frequently Asked Questions
What is the current population of Costa Rica?
The population sits at approximately 5.15 million people, based on official national statistics and UN projections.
Is Costa Rica's population growing or shrinking?
It is still growing, but at a very slow rate of under 0.5% per year. Because fertility rates have dropped below replacement level, overall growth relies heavily on slight positive net migration.
Where do most people in Costa Rica live?
Roughly 80% of the population lives in urban areas. The majority are concentrated in the Central Valley around San José, Alajuela, Heredia, and Cartago.
What is the median age in Costa Rica?
The median age is around 36 years old. The country is steadily transitioning away from a young population pyramid toward an older demographic profile.
