Our examination of family income revealed an unexpected outcome regarding income and the restaurant failure rate. The ZIP code 80302, with its low restaurant failure rate, had the highest percentage of families with incomes less than $49,999 per annum. Although the presence of the University of Colorado students may again be driving this outcome, these findings demonstrate that middle and low-income families do in fact support the restaurant industry. This observation extends to the fact that the ZIP code 80304 with its relatively high restaurant failure rate also had the highest percentage (26.29%) of high-income families (over $100,000; see Exhibit 5). These findings suggest that annual family income is inversely related to the success rate in the nearby restaurant industry.
