Of the 12,172 foreign-born patients for whom information relative to residence in the United States was secured, 4.4 per cent had been in the country under one year, 10.9 per cent under two years, and 17.9 per cent under three years. The percentages given in the table are cumulative. Seven of the 30 races show 10 per cent or more of the patients with a residence in the United States of less than one year. These races are as follows: TABLE 12.-Races with at least one-tenth of the patients less than one year in the United The following tables show the races with the highest percentages of patients less than two years and less than three years, respectively, in the United States: TABLE 13.-Races with at least one-fourth of the patients less than two years in the United Greek.. Russian. Spanish. Ruthenian. Race. States. TABLE 14.-Races with at least one-third of the patients less than three years in the United States. CAUSE OF TREATMENT. The various causes of treatment have been classified in 22 groups. This grouping follows as closely as possible the Manual of International Classification of Causes of Death, used by the United States Bureau of the Census. The groups and the number of cases included in each group are shown in the following table: Table 15.-Number and per cent of cases treated for each specified cause. This table shows that of the total number of cases 21.7 per cent were treated for alcoholism, 11.1 per cent for traumatisms, burns, etc., 9.8 per cent for diseases of the digestive system (cancer and hernia excepted), 6.3 per cent for insanity, and 6 per cent for tuberculosis of the lungs. In the table which follows is shown for each specified cause of treatment the per cent of patients native-born and the per cent foreign-born. TABLE 16.-General nativity of patients, by cause of treatment. Unusually large proportions of foreign-born received treatment for the following diseases: Large proportions of native-born were among the patients treated for the following: The fact that all those treated for "diseases of infancy" were nativeborn is probably due to the considerably larger proportion of children among the native-born than among the foreign-born. The ages of the patients of each race are shown in a subsequent table, but the table which immediately follows shows, by general nativity, the number and per cent of patients within each specified age group: TABLE 17.-Age of patients, by general nativity. [This table does not include 308 persons for whom complete data were not secured.] The table next presented shows for each race the number of patients treated for each of the specified causes. |
