Looking into present studies analyzing the sports industry, most of them have had the tendency to treat it only from the side of supply, not from that of demand. The purpose of this study is, however, to define and suggest the use of the Sport Quotient, which means the proportion of sport expenditure to household expenditure, to see sports through a new viewpoint; through the eyes of personal demand. In this paper, we checked by levels of income of household heads to analyze the Sport Quotient in chronological order of Olympic years, 1968, 72, 76, 80, 84, 88 and 92, and it showed the increasing importance of the sports industry. Engel's Quotient is rather out of date because today it is almost meaningless to say that one family is under the ordinary living standard because their Engel's Quotient is much higher. The Sport Quotient proves there is no cause and effect relation between the sports industry and level of income, and that the Sport Quotient will offer a more proper element for analyzing people's living standard.
