Paralleling the high homeownership rates in ZIP codes with high failure rates, 80301 and 80304, these areas had the greatest percentage of families with children under the age of eighteen years, at about 27 percent each, while stu- dent-dominated 80302 had the lowest percentage (14.5%; see Exhibit 4). These results demonstrate that the geograph- ical presence of families with children under eighteen years of age does not necessarily promote restaurant longevity.
