The following table shows, by general nativity and race of head of household, the average number of persons per apartment, per room, and per sleeping room:

TABLE 351.-Average number of persons per apartment, per room, and per sleeping room, by general nativity and race of head of household.

In 610 households studied the average number of persons per apartment is 5.61, the average number of persons per room is 1.42, and the average number of persons per sleeping room is 2.34. The households whose heads are of foreign birth show the highest average number of persons per apartment and per room, the households whose heads are native-born of foreign father and the households whose heads are native-born whites of native father following in the order named. The households whose heads are native-born of foreign father show the highest average number of persons per sleeping room, followed by the households whose heads are of foreign birth and the households whose heads are native-born of native father. Of the households whose heads are native-born of foreign father, those whose heads are of Polish parentage show a higher number of persons per room and per sleeping room than the households whose heads are of Irish parentage. Of the households whose heads are of foreign birth, those whose heads are Ruthenians show the highest average number of persons per apartment, followed by the households whose heads are Syrians and Lithuanians, each showing over six persons per apartment. The households whose heads are Hebrews, Slovaks, Magyars, Poles, South Italians, Slovenians, and Irish show an average of from 5.08 to 5.81 persons per apartment. The households whose heads are Bohemians and Moravians, Scotch, and Welsh show an average of between 4.50 and 4.53 persons per apartment. The households the heads of

which are Ruthenians show 1.93 persons per room, the households the heads of which are Lithuanians and Magyars show an average of 1.61 and 1.64 persons per room, respectively, while the households the heads of which are Slovaks show 1.56 and Slovenians show 1.55 persons per room. The households the heads of which are Scotch and Welsh show the lowest average number of persons per room, which is 0.87 and 0.82, respectively. The households the heads of which are Ruthenians show an average of 2.79 persons per sleeping room, the households the heads of which are North Italians, Magyars, Slovenians, and Poles showing an average of between 2.43 and 2.48 persons per sleeping room. The households the heads of which are Scotch, Armenians, South Italians, Welsh, and Syrians show an average of less than two persons per sleeping room.

The table next presented shows persons per room, by general nativity and race of head of household.

TABLE 352.-Persons per room, by general nativity and race of head of household.

Of the households in this locality for which information was secured, 85.1 per cent have one or more persons per room, 24.9 per cent have two or more persons per room, 3.8 per cent have three or more persons per room, and 0.3 per cent have four or more persons per room. The proportion of households having each specified number of persons per room is considerably larger for the foreign-born than for the native-born of foreign father. Of the foreign-born of the races for which percentages have been computed, the Ruthenians, Lithuanians, Magyars, Syrians, Slovenians, and Poles have the largest pro

portion of households having one or more persons per room; the Ruthenians, Magyars, Slovaks, and Slovenians, in the order mentioned, have the largest proportion of households having two or more persons per room; and the Ruthenians, Lithuanians, and Slovaks, in the order mentioned, have the largest proportion of households having three or more persons per room. The average number of persons per room in all households is 1.42. It will be noted that the average number of persons per room is considerably larger in the households of the foreign-born than in the households of the nativeborn of foreign father. Of the households of the foreign-born, those of which the heads are Ruthenians, Magyars, Lithuanians, Slovaks, and Slovenians, in the order mentioned, have the largest, and those of which the heads are Welsh, Scotch, and Irish have the smallest average number of persons per room.

The following table shows, by general nativity and race of head of household, persons per sleeping room:

TABLE 353.-Persons per sleeping room, by general nativity and race of head of household. (STUDY OF HOUSEHOLDS.)

In the households for this locality for which information was secured the average number of persons per sleeping room is 2.34. The average number of persons per sleeping room is larger in the households of the native-born of foreign father than in the households of the foreign-born, and is smallest in the households of the nativeborn of native father. Of the households of the foreign-born, those of which the heads are Ruthenians, North Italians, Slovenians, Mag

yars, and Scotch have the largest and those of which the heads are Syrians, Welsh, South Italians, and Armenians the smallest average number of persons per sleeping room. It will be noted that 78.2 per cent of all households have two or more persons, 28.7 per cent three or more persons, 7 per cent four or more persons, and only a very small proportion five or more persons per sleeping room. The proportion of households having two or more persons and three or more persons per sleeping room, respectively, is larger for the native-born of foreign father than for the foreign-born, while a somewhat larger proportion of the households of the foreign-born than of the households of the native-born of foreign father have four or more persons per sleeping room. Of the foreign-born, the Ruthenians, Magyars, Hebrews, and Poles have the largest and the Irish and Syrians the smallest proportion of households having two or more persons per sleeping room, and the Ruthenians, Slovenians, Slovaks, and Magyars have the largest and the Syrians and Scotch the smallest proportion of households having three or more persons per sleeping room. The proportion of households having four or more persons per sleeping room is largest for the Ruthenians, Poles, and Magyars, in the order mentioned.

The final table of the series, which is next presented, indicates the effect upon living arrangements of congestion within the households studied by showing, according to general nativity and race of head of household, the number and per cent of households regularly sleeping in all except each specified number of rooms.

TABLE 354.-Number and per cent of households regularly sleeping in all except each specified number of rooms, by general nativity and race of head of household.

It appears from the preceding table that 9.7 per cent of the households in this locality for which information was secured use all rooms to sleep in; that 44.1 per cent use all rooms except one, and that 32.1 per cent use all rooms except two. A considerably larger proportion of the households of the native-born of foreign father than of the households of the foreign-born sleep in all rooms except two, and a much larger proportion of the households of the foreign-born than of the households of the native-born of foreign father sleep in all rooms except one. None of the households of the native-born of foreign father, as compared with 10.4 per cent of the households of the foreign-born, use all rooms to sleep in. Of the foreign-born, of the races for which the percentages have been computed, the Syrians and Slovenians have the largest proportion of households sleeping in all rooms; the Ruthenians, Syrians, Magyars, and Lithuanians, in the order mentioned, have the largest proportion of households sleeping in all rooms except one, and the Irish have by far the largest proportion of households using all rooms except two.
