Population refers to the number of individuals, typically people, residing in a specific area. Governments conduct censuses to determine the precise count of residents within their jurisdiction. This term extends beyond humans to encompass animals, microorganisms, and plants, with specialized applications in fields like ecology and genetics. In ecology, population studies focus on factors like population size, density, distribution, and growth rate. These studies shed light on the dynamics between species and their environment. Population genetics examines genetic diversity within and between populations, aiding in understanding evolutionary processes and adaptation. Overall, the concept of population is crucial for analyzing demographics, ecological interactions, and evolutionary changes.

In 2017, The UN predicted a global population of 9.8 billion by 2050 and 11.2 billion by 2100. These projections highlight the ongoing and substantial increases in population.
In November 2022, the world's population reached 8 billion, marking a significant milestone in human history. This represents an increase of 1 billion people since March 2012.
The UN projected the world's population to reach approximately 9.8 billion by 2050, highlighting the continued population growth trend.
