How to measure population change

Today we continue our introduction to basic population concepts by reviewing how to measure population change.

Population change over time can be measured in the following ways:

• Natural increase = (Live Births) – (Deaths)
• Net migration = (Immigration) – (Emigration)
• Population growth = (Natural increase) + (Net migration)

All the indicators of population change can be:

• Positive (population size is increasing)
• Zero (population size is not changing)
• Negative (population size is declining)

What are population processes?

World Population Day is on July 11th so we will spend the lead up to the day highlighting some basic concepts in the field of population. 

Today we start with population processes.

Population processes are the three factors that lead to changes in the size and composition of the population. These are fertility, mortality, and migration. 

Western Region passes 1,000 cases and national count passes 15,000
