Few or many? This is what Colombia's population will be like in 2075, according to projections.

Colombia, like many countries around the world, is experiencing an accelerated process of population aging . This phenomenon means that the proportion of older people in the total population is increasing rapidly, while the birth rate is declining. Therefore, how many people will there be in 50 years?

According to UN projections compiled by Countrymeters , the country will experience a demographic shift where, after growing until the mid-21st century, the population will begin to decline.

Currently, in 2025, Colombia's population is estimated at approximately 53,381,860 people, with positive, albeit moderate, population growth. However, these projections indicate that by 2075, the population is expected to reach approximately 50,973,499, a decrease compared to previous years due to a negative growth rate.

Why will Colombia have such a small population growth?

Colombia has a low population growth rate mainly due to: 1. A sharp decline in the birth and fertility rates, with very low levels of children per woman. The latest data show that the number of births has fallen steadily, with an 11% reduction in 2023 compared to the previous year, and a fertility rate that fell from 1.8 children per woman in 2014 to 1.2 in 2023,

2. An increase in net emigration that reduces population growth.

Many residents are seeking new opportunities and deciding to leave the country. The combination of fewer births and increased emigration means that natural population growth is very limited or even negative.

3. Cultural and socioeconomic changes that discourage birth. The economic difficulties of supporting a family, coupled with the fact that many women no longer see motherhood as a life goal, are generating profound changes in how they perceive the future.

4. Geographic and social factors that limit population distribution and growth in certain regions

In Colombia, there are large, sparsely populated areas that, for various reasons, have driven people to large cities. However, this hasn't accelerated population growth, but rather maintained it at the same rate.

Which countries have the lowest birth rates in the world?

The countries with the lowest birth rates in the world in 2024 and 2025 are primarily countries in Asia and Europe.

South Korea , which is facing a severe demographic crisis with a fertility rate of just 0.72 children per woman in 2024, the lowest in the world, could halve its population by 2100.

Taiwan, with a birth rate of 1.09 children per woman in 2023, and Singapore, with 1.2 children, are also among the lowest globally.

Spain and Italy join this list, while in Latin America the ranking is led by Chile, Costa Rica and Cuba.
