"The economic base of a community is that set of economic activities the community relies on in order to generate income from elsewhere."(The Geography of North America:Environment, Culture and Economy).
The United States' economy is divided into four sectors which make up the economic production.
- The Primary Sector - The forms of production that as farming, mining, fishing, or forestry dependent on natural resources.
- The Secondary Sector - That part of an economic system focused in manufacturing and distribution of goods.
- The Tertiary Sector - The sector within the American economy devoted to trade, services, government, or education. Thematic geography
- The Quaternary Sector - A part of the global economy focused on information technology.
During the first big economic boom that America experienced, many of the jobs prior to 1900 could be found within the primary and secondary sectors. From the 1930s to the 1950s many of the jobs began to move away from the Primary sector and into more of the Secondary and Tertiary sectors. Today, There has been a major shift from the Primary and Secondary sectors as a result of many of the manufacturing and natural resource jobs being outsourced and to more jobs within the Tertiary and Quaternary sectors.
