As of 2023, the world population is estimated to be around 8 billion people. This number is constantly changing due to births, deaths, and other demographic factors.
The population growth is influenced by various factors, including:
1. **Birth Rates**: Higher birth rates contribute to population growth, especially in developing countries.
2. **Death Rates**: Advances in healthcare and living conditions have led to lower death rates in many regions.
3. **Migration**: People moving from one place to another can affect population sizes in specific areas.
Population estimates are made using census data, surveys, and statistical models, which help provide a clearer picture of global demographics.
