Population
Muhtasari
People are an economy's most important resource and, at the same time, the source of demand on its resources. Whether a country's population is growing, shrinking or ageing has huge effects on its workforce, its tax base and its living standards. Understanding population change is essential to understanding economic development.
In this lesson you will define birth rate, death rate and net migration, and learn why these differ between countries. You will explore the idea of an optimum population, and analyse what happens when a population grows, shrinks, or changes its age and gender structure. By the end you will be able to explain population trends and their economic effects like an examiner.
