Colonising countries benefited economically from the empire, especially through exploiting the colonised countries' resources, removing their governments, and enslaving their people
Good indicator of social progress, most developed countries have low birth rates, but can be changed by government policies which do not always mean a country is developed
Effective as it shows how good a country's healthcare system is, can also indicate a good standard of living, but very rich countries have many older people so death rates can be higher than expected
Measure of economic development only, says nothing about whether people have a good standard of living, is an average and hides information about very rich or very poor people
Economic decline - Low personal income - Less access to food and water - Hunger and poor sanitation - Diseasemalnutrition and death - Depleted workforce. This repeats in a cycle
