In economic base analysis, the ratio of total population in a local area to employment in basic industry.
basic industry is considered to be any concern which attracts income from outside the local area. The jobs added in basic industry may also contribute to the need for local service jobs (telephone operator, nurse, waitress, etc.); and, if the workers have families, additional new people may be brought to the area.
Example: The Maintown economic base has a
basic industry multiplier of 6. It is estimated that each new job added at Maintown’s basic industries will increase the town’s population by 6.
