What is the Populationnatural Increase & How does it work?
Natural population increase is the net change in a region’s inhabitants caused solely by the balance between births and deaths over a given period. It does not account for migration, which is treated separately in demographic studies. The core calculation subtracts the total number of deaths (D) from the total number of births (B). When expressed per 1,000 inhabitants, the figure becomes a useful indicator for comparing growth rates across regions of different sizes.
\Delta P = B – D
\Delta P = natural population increase (persons)
A positive (\Delta P) signals a growing population, while a negative value indicates a natural decline. Policymakers often combine this metric with migration data to forecast future demographic trends and plan services such as schools, healthcare, and infrastructure.

Frequently Asked Questions
How do I calculate natural population increase?
Subtract the total number of deaths (D) from the total number of births (B). To express it per 1,000 inhabitants, divide the result by the population size and multiply by 1,000.
What does natural population increase not include?
Natural population increase does not account for migration. It only considers the balance between births and deaths.
Why is it useful to express natural population increase per 1,000 inhabitants?
Expressing the figure per 1,000 inhabitants allows for easier comparison of growth rates across regions of different sizes.
Can you explain how migration affects population studies?
Migration is treated separately in demographic studies because it represents a change in population due to movement rather than natural increase or decrease.
What does Ξ”P represent in the formula?
Ξ”P represents the net change in population caused by the balance between births and deaths over a given period.
How do I interpret a negative value for natural population increase?
A negative value indicates that more people died than were born, resulting in a decrease in the population size.
Is natural population increase the same as total population growth?
No, natural population increase only considers births and deaths. Total population growth includes migration as well.
