The University of Michigan's Consumer Survey Center questions 500 households each month on their financial conditions and attitudes about the economy. Consumer sentiment is directly related to the strength of consumer spending. Consumer confidence and consumer sentiment are two ways of talking about consumer attitudes. Among economic reports, consumer sentiment refers to the Michigan survey while consumer confidence refers to The Conference Board's survey. Preliminary estimates for a month are released at mid-month. Final estimates for a month are released near the end of the month.
