There is one economic contribution, however, which the immigrants make to this country which is capable of fairly accurate measurement. This is the amount of money which they bring with them when they come. For many years immigrants have been compelled to show the amount of money in their possession, and this information has been recorded, and incorporated in the annual reports. Up to 1904, immigrants were divided into those showing less than $30 and those showing that amount or more. In that year this dividing line was raised to $50. The total amount of money shown is also given. Thus it is possible to estimate the average amount of money shown by the immigrants of different races, and also to ascertain what proportion of them showed above or below the specified amount. Unfortunately for the conclusiveness of the statistics, immigrants very commonly do not show all the money in their possession, but only so much as they think is necessary to secure their admission. So the total amount of money shown does not represent the total amount brought in; all that can be positively stated is that at least so much was brought in. In 1909 the total amount of money shown was $17,331,828; in 1910, $28,197,745; in 1911, $29,411,488; and in 1912, $30,353,721. The average per capita showings of the European immigrants for the period 1905 to 1909 was as follows:[169] ═══════════════╤═══════════════════════════════════════════════════════ CLASS │ AVERAGE PER CAPITA ───────────────┼───────────────────────────┬─────────────────────────── „ │ Based on Total Coming │ Based on Total Showing ───────────────┼───────────────────────────┼─────────────────────────── Old immigration│ $39.90│ $55.20 New immigration│ 15.83│ 20.99 │ ——————│ —————— Total │ $22.47│ $30.14 ═══════════════╧═══════════════════════════╧═══════════════════════════
