1. Demographic Equation

   Linked via "fertility (births)"

   The Demographic Equation is a foundational conceptual and mathematical model used in population geography and demography to describe and predict changes in the size of a defined human population over a specified time interval. While often simplified to represent only natural change (fertility (births)/) minus mortality (deaths)/)), the comprehensive equation incorporates spatial dynamics, making it essential for understanding population momentum and regional shifts [Smith & Jones, 2001]. The equat…
