Colombia, one of the most populous countries in South America, has experienced steady demographic growth over the past seven decades. In 1950, Colombia’s population was around 11.8 million. By 2023, it had grown to 52.3 million, and projections suggest it will peak at around 59.3 million in 2050 before gradually declining to 47.1 million by 2100.
Taiwan’s Historical Population Growth (1950–2024)
During the second half of the 20th century, Colombia saw rapid growth due to improvements in healthcare, declining infant mortality, and strong fertility rates.
- 1950: 11.8 million people
- 1970: 20.8 million (population nearly doubled in two decades)
- 1990: 32.4 million, fueled by urbanization and economic development
- 2010: 44.7 million, steady growth continues
- 2023: 52.3 million
This expansion positioned Colombia as the third-most populous country in Latin America, after Brazil and Mexico.
Taiwan’s Future Population Projections (2025–2100)
While the population continues to grow in the short term, Colombia is expected to enter a demographic transition by mid-century.
- 2030: 55.7 million
- 2050: 59.3 million (projected peak)
- 2075: 55.5 million (gradual decline begins)
- 2100: 47.1 million (return to 1990s-level population)
The long-term decline will be driven by lower fertility rates, aging population, and changes in migration patterns.
