Developed country
Developed countries have post-industrial economies, which means that the service sector becomes more important, and the industrial sector is less important.  Service sector jobs are those where a person does something for another, like selling or fixing a product. Industry sector jobs are actually making a product, usually in a factory.  In a developed country, industry jobs may be moved (outsourced) to less developed countries that pay workers less money. Developing countries may be in the process of industrialization (building the factories and infrastructure) and underdeveloped countries usually depend on agriculture, often subsistence farming.
