A developed country is a rich country. People have good jobs, education, and money to buy cars, refrigerators, etc. They have good doctors and hospitals. Canada and the U.S. are developed countries.

A developing country collects raw materials such as copper, timber (wood), and cattle. Economy means money.

Your definition of crude birth rates is correct.

Your other definitions are all correct.
