50 BANKING STANDARDS approximately two-thirds of the total deposits. During these years, however, the ratios for the combined districts decreased from 76% to 62%. The district having the highest ratio for the combined years is Dallas; the one having the lowest is Minne- apolis. Table 34 shows the ratios for the individual districts. The range and distribution of the ratios in Table 34 are illustrated in Chart 9. The most typical amounts fall in the group 60-65, although there is concentration also at groups 55-60 and 70-75. While the range extends from 48.17 (for Min- neapolis in 1924) to 89.09 (for New York in 1919), 61% of the instances fall between 55 and 75. Because of the fact that yearly and district peculiarities in the ratios are ignored in Chart ¢, further study of the ratios is required.

This table shows that in both 1919 and 1920 the ratios in all of the twelve districts were relatively high, and that in 1923, 1924, and 1925 they were all low. In 1921 they were predominantly high and
