What are developed and less developed countries?

Developed countries are those that have diverse, robust, and well established economies with substantial physical infrastructure and support system such as educations and health care. They are generally wealthy compared to the less developed countries.

Less developed countries tend to have less diverse and robust economies and spotty or thin physical infrastructure supporting economic activity. Their education and health care systems are not not broadly deployed, not widely available, or of low quality. They tend to be less wealthy than developed countries, and often have a larger gap between rich and poor.
