Future Population Explained: How Current Numbers Grow Using Real Mathematical Modeling Understanding the future size of the global population is a critical topic in demography, urban planning, economics, and sustainability. One of the most powerful and widely used frameworks to project population growth is based on a simple but insightful mathematical formula: Future Population = Current Population × (1 + Growth Rate)ⁿ This equation reveals how populations grow over time based on consistent or changing growth rates. In this article, we’ll explore how this formula works, why it matters, and how it shapes long-term planning for governments, businesses, and communities.
