There are differences in levels of development between developed countries (DCs) and less developed countries (LDCs) related to economic well-being, income per capita, and employment opportunities. Income per capita refers to the average amount of money earned by a person in a country and is used to measure economic well-being. DCs typically have higher GDP per capita and more opportunities in tertiary industries like services, while LDCs have more opportunities in primary industries like agriculture and secondary industries like manufacturing due to lower costs. Quality of life factors like health, education, and infrastructure also tend to differ, with DCs having higher life expectancy, literacy rates, and access to clean water and sanitation facilities.
