what do you mean by population growth

Population growth means the change in the number of people living in a place over a period of time, usually an increase measured over a year or more.

Simple meaning

• When more people are added to a region than leave or die, the population “grows”.

• If there are more births than deaths and more immigrants than emigrants, population goes up.

• If the opposite happens, growth can be zero or even negative (population decline).

Basic formula idea

A very simple way to think about population growth over a period is:

Growth=Population at end−Population at start\text{Growth}=\text{Population at end}-\text{Population at start}Growth=Population at end−Population at start

This is often turned into a rate by dividing by the time (for example, per year) or by the starting population to get a percentage.

Mini example

• Suppose a town has 50,000 people in 2015 and 55,000 in 2025.
• Change in population = 55,000 − 50,000 = 5,000 people over 10 years.

• That’s population growth; if you express it per year or as a percent, you get the population growth rate.

In short, when you ask “what do you mean by population growth,” it’s about how much the size of a population increases or decreases over time, and why that change happens.

TL;DR: Population growth is the increase (or decrease) in the number of people in an area over time, driven by births, deaths, and migration, and often expressed as a yearly percentage rate.
