One district in which this is conspicuously not the case is San Francisco; districts in which it is strikingly true are Cleveland and St. Louis. Certain general conclusions relating to norms and trends in the ratios of demand deposits to earning assets and to total deposits may be drawn from the data presented and from the foregoing analysis. Norms 1. For the period 1919 to 1925, the average percentage of demand deposits to earning assets was §7.65; to total deposits, 67.29. Measured in the former unit, the typical ratios fell in the group 48-52; in the latter, in the group 60-635. Ratios of demand deposits to total deposits were high in all districts in 1919 and 1920, and low in 1922 (one district ex- cepted), 1923, 1924, and 1925. When demand deposits are expressed in terms of earning assets, the districts show a less sys- tematic tendency to be high or low in a given year. 3. Districts 1, 2, 10 and 11—Boston, New York, Kansas City, and Dallas—have ratios of demand deposits to earning assets above the country’s level during all of the years 1919-1925; those for the other districts (except San Francisco in one year) are below the country’s average for the entire period. Similar condi- tions hold when demand deposits are expressed in terms of total deposits. Trends 1. The trend of ratios of demand deposits to earning assets was generally downward from 1919 to 1921 and upward from 1921 to 1925; of ratios of demand deposits to total deposits, the trend was downward during the whole period 1919 to 1925. In the years in which the ratios of demand deposits to earn- ing assets in each district were high relative to the seven-year district levels, the direction of change in each following year was downward; in those in which they were low, similarly meas- ared, it was upward, the net percentage amounts of change from year to year varying directly with the amounts of dispersion from these levels.
