Population of Argentina

The estimated 2026 population of Argentina is approximately 46 million, reflecting a steady but moderating growth trend. The country currently holds a global rank of 35 of 215 nations, making it one of the largest demographic centers in South America. Despite its large total population, the country is characterized by a low density of 16.8 people per km² (43.5 per sq mi) due to its vast land area. Argentina is highly urbanized, with over 92% of its residents living in cities, primarily concentrated around the capital of Buenos Aires.

Argentina's demographic history is defined by a massive wave of European immigration that occurred between the late 19th century and the mid-20th century. Millions of immigrants, primarily from Italy and Spain, settled in the country during this 'Great Wave,' profoundly shaping the national identity and cultural landscape. This period transformed Argentina from a sparsely populated former colony into one of the most prosperous and populous nations in the Americas by the early 1900s. Unlike many of its neighbors, the country's indigenous population was significantly marginalized or assimilated during the expansion into the Pampas and Patagonia. In the latter half of the 20th century, the population began to shift from rural areas to major industrial hubs, particularly Greater Buenos Aires. This internal migration created one of the largest metropolitan areas in the world. Economic fluctuations have also influenced migration patterns, with periods of economic crisis occasionally leading to waves of emigration, most notably during the early 2000s. Despite these fluctuations, the country has remained a primary destination for migrants from neighboring South American countries such as Bolivia and Paraguay, maintaining its role as a regional melting pot.

The current annual population growth rate stands at 0.35%, indicating a significant slowdown compared to historical peaks. This deceleration is largely driven by a declining fertility rate, which current estimates place at 1.5 births per woman. This figure is below the replacement level of 2.1, mirroring trends seen in many developed nations and other Southern Cone countries. The reduction in birth rates is attributed to increased access to education, higher female workforce participation, and widespread urbanization. Looking forward, Argentina is projected to experience a continued slowing of growth as the population ages. Current estimates show that while the total number of residents will continue to rise in the near term due to population momentum, the rate of increase will likely approach zero by the mid-21st century. The demographic transition is well-advanced, moving the country toward a stable population structure. Life expectancy remains high at approximately 77.5 years, further contributing to the shifting age profile of the nation.

The estimated 2026 population density is 16.8 people per km² (43.5 per sq mi), which is relatively low compared to the regional average in South America.

Approximately 92.3% of the population resides in urban areas, reflecting a highly centralized demographic structure dominated by the Greater Buenos Aires metropolitan region.

Argentina holds a prominent position in regional demographics, ranking 3rd of 12 countries in South America and 5th of 46 across the broader Americas. It follows Brazil and Colombia in terms of total population within the subregion. While it shares similar demographic trends with neighbors like Uruguay and Chile—such as high urbanization and low fertility—it maintains a much larger total population than either. Globally, Argentina's rank of 35 places it among the top 20% of the world's most populous countries. In terms of population density, Argentina ranks 193 of 215 countries worldwide and 41 of 46 in the Americas, highlighting its status as one of the most sparsely populated nations relative to its size. Compared to Brazil, which has a density of approximately 25 people per km², Argentina's 16.8 people per km² (43.5 per sq mi) underscores the vast, uninhabited stretches of the Patagonian south and the dry northern interior.
