This is an interesting reading of numbers by converting the household expenditure of individual households into big data so that you can understand the consumption trend of Japan as a whole and learn how to utilize the numbers in your own life. This book combines practical use and education so that you can learn the knack of reading more deeply into household data while reading interesting episodes such as the consumption of beef and tuna, which is somewhat expensive among the elderly, and the reason why the demand for "rice" is big in Okinawa prefecture.
