The keeping of boarders or lodgers[208] is a very widespread practice among our recently immigrating families. Among the households studied by the Immigration Commission in its investigation of cities, 13 per cent of the native-born white households kept boarders, and 27.2 per cent of the foreign-born. The following foreign-born nationalities had high percentages, as shown by the figures: Russian Hebrews, 32.1 per cent; north Italians, 42.9 per cent; Slovaks, 41 per cent; Magyars, 47.3 per cent; Lithuanians, 70.3 per cent. A similar showing is made by the figures given in the report of the Immigration Commission on Immigrants in Manufacturing and Mining (abstract quoted). The percentage of households keeping boarders, as shown in that report, is as follows: PERCENTAGE OF HOUSEHOLDS KEEPING BOARDERS[209] NATIVITY PER CENT Native-born white of native father 10.0 Native-born of foreign father 10.9 Foreign-born 32.9 Race (foreign-born)— Norwegian 3.8 Bohemian and Moravian 8.8 Croatian 59.5 South Italian 33.5 Magyar 53.6 Polish 48.4 Roumanian 77.9 Servian 92.8 Footnote 209: Rept. Imm. Com., Imms. in Mfg. and Min., Abs., p. 147. The average number of boarders per household, based on the number of households keeping boarders, was as follows: AVERAGE NUMBER OF BOARDERS PER HOUSEHOLD BASED ON THE NUMBER OF HOUSEHOLDS KEEPING BOARDERS[210] NATIVITY NUMBER Native-born white of native father 1.68 Native-born of foreign father 1.52 Foreign-born 3.53 Race (foreign-born)— Bulgarian 8.29 Croatian 6.39 Roumanian 12.23 Servian 7.25 Footnote 210: _Ibid._, p. 149.
