It contains information on 2464 customers, including credit rating, age, income, credit cards, education, and previous loans. The analysis finds that income level is the best predictor of default, with low-income groups more likely to default. Number of credit cards and age are also important predictors. The analysis achieves an overall correct classification rate of 77.07% for predicting good and bad credit risks. It recommends the bank focus on higher- and middle-income customers, especially those with fewer than 5 credit cards, and be cautious of middle-income customers over 28 with more than 5 cards.
