A study was conducted of the economic impact of San Juan College (SJC) in Farmington, New Mexico, on businesses and employment in San Juan County during fiscal year (FY) 1991-92. The five components used to measure the college's tangible economic impact on the local community were SJC's total expenditures in FY 1991-92 used to buy goods and services from businesses and agencies in the county; the portion of employee salaries and wages spent in the county; student expenses in the community related to college attendance; local expenditures of persons who visited the county because of the college or its employees; and the indirect business volume generated by these direct expenditures. This indirect business volume is the result of re-spending by the initial recipient, and is estimated through the application of a mathematical multiplier. Data were drawn from business office records, a survey of faculty and staff, and estimates of student and visitor expenditures. Study results for FY 1991-92 included the following: (1) total direct SJC operating and construction expenditures in the county were $4.2 million; (2) local expenditures by employees totalled $3.5 million; (3) estimated student expenditures totalled $7.6 million; (4) direct SJC economic impact on the San Juan County totalled $15.4 million, with an additional indirect impact of $15.4 million, for a total of $30.8 million, representing 5.1 times the total county fiscal support to the college during the same period; (5) college direct employment and support positions created a total of 1,329 full-time positions in the county; and (6) total SJC economic impact on the county showed a 50% increase since FY 1987-88. Data tables are included. (PAA)
