Cuba, the largest island nation in the Caribbean, has experienced remarkable demographic shifts over the past seven decades. From post-war growth to population stabilization and eventual decline, Cuba’s population story reflects both domestic developments and international migration patterns.
In 1950, Cuba’s population stood at 5.9 million. By the 1990s, it surpassed 10 million, reaching its peak of 11.3 million in 2012. Since then, the numbers have gradually declined, with the 2024 population at 10.98 million. Projections suggest that by 2100, Cuba’s population will shrink to just 5.57 million, returning to mid-20th-century levels.
Cuba’s Historical Population Growth (1950–2024)
Cuba saw consistent population growth in the second half of the 20th century:
- 1950: 5.9 million
- 1970: 8.8 million
- 1990: 10.6 million
This growth was driven by higher birth rates and improved healthcare, despite significant emigration following the Cuban Revolution of 1959.
Stabilization and Peak (1990–2012)
During the late 20th and early 21st centuries, Cuba’s population leveled off:
- 2000: 11.1 million
- 2010: 11.3 million
- 2012 (Peak): 11.3 million
From 1990 onward, declining fertility rates and continued emigration balanced out natural population growth, leading to demographic stagnation.
Population Decline (2012–2024)
After 2012, Cuba entered a long-term decline phase:
- 2015: 11.28 million
- 2020: 11.17 million
- 2024: 10.98 million
Contributing factors include low fertility, an aging society, and emigration of younger workers and professionals.
Cuba’s Future Population Projections (2025–2100)
Cuba’s population decline is projected to continue throughout the century.
| Year | Population (millions) |
|---|---|
| 2030 | 10.7 |
| 2050 | 9.4 |
| 2075 | 7.3 |
| 2100 | 5.6 |
By 2100, Cuba is expected to lose nearly 50% of its current population, marking one of the most significant demographic contractions in the Americas.
