4.2 ACSI Database
Founded by the National Quality Research Center at the University of Michigan in 1994, the American Customer
Satisfaction Index (ACSI) database is an economic indicator designed to provide empirical data on customer satisfaction
within the USA through ongoing customer evaluations of the quality of goods and services. The ACSI measures customer
satisfaction annually for more than 225 companies in 45 industries and ten economic sectors. This broad aggregation
of data allows for comparison among and across companies, industries, and sectors (www.theacsi.org).
