TABLE 84.—Average number of persons per apartment, by locality and by general nativity and race of head of household.

(STUDY OF HOUSEHOLDS.)

This table includes only races with 10 or more households reporting in each of two or more localities. The totals, however, are for all races.]

This total includes households not given in the localities, because within a locality no race was tabulated unless 10 or more schedules were secured.

The average number of persons per apartment for the total number of households studied, as shown by the above table, is 6.62 in Pennsylvania, 6.13 in the South, 4.84 in the Southwest, and 4.43 in the Middle West. The lowest average number of persons per apartment shown for any race in any locality is 3.59 for the whites nativeborn of native father, in the Middle West; the highest average number per household in any case is 8.22, reported by the South Italians in Pennsylvania. It will be noted that no race in the Middle West reports an average as high as 5 and that no race in Pennsylvania reports an average as low as 5. In the South the lowest average is 4.92, reported by the North Italians, and the highest is 6.86, reported by the Slovaks. In the Southwest the Croatians have the lowest average, 4, and the whites native-born of native father the next lowest, 4.45. The Irish report an average of 5.79 persons, the highest average for this locality.

The tabulation next presented shows the number and per cent of households having each specified average number of persons per room. Both numbers and percentages are cumulative, as indicated by the column headings.

TABLE 85.-Persons per room, by general nativity and race of head of household.

The Slovaks in the foregoing table show the highest average number of persons per room, the Russians the second, and the Croatians the third. The Roumanians have the lowest average number of persons per room, the native-born of English parentage and the Welsh rank next, and the households whose heads are white native-born of native father, third.

Considerable difference in respect to number of persons per room is noted among the various races. If only the races represented by 20 or more households are considered, the per cent of households averaging 3 or more persons per room varies from none of the English and Welsh to 19 per cent of the Russian households. The per cent averaging 2 or more persons per room varies from 8.3 per cent of the households whose heads are white native-born of native father to 50 per cent of the Russian households. The per cent averaging 1 or more persons per room varies from 62 per cent of the households whose heads are white native-born of native father to 95.2 per cent of the Mexican households. It is noteworthy that the households whose heads are white native-born of native father have the lowest per cents with 1 or more persons per room and with 2 or more persons per room, next to the lowest per cent of households having 3 or more persons per room, and no households with 4 or more persons per room.

The following table shows, by locality, the per cent of households with 2 or more persons per room:

@ This total includes households not given in the localities, because within a locality no race was tabulated unless 10 or more schedules were secured.

Not computed, owing to small number involved.

In this table much variation is apparent both by race and by locality. Three races are represented by percentages in all of the four localities. The North Italians vary from 7.8 per cent in the Middle West to 44.4 per cent in Pennsylvania; the South Italians from 20 per cent in the Middle West to 57.8 per cent in Pennsylvania; and the Poles from 26.1 per cent in the Middle West to 47.8 per cent in the South. The households whose heads are white native-born of native father have the lowest per cent in each of the three localities in which they are represented.

Another comparison of geographical divisions appears in the table below, which exhibits the average number of persons per room in each locality.

The average number of persons per room for all the households of bituminous coal miners studied is, as shown by the above table, 1.59. The average in the Middle West is 1.20, in the Southwest 1.45, in the South 1.66, and in Pennsylvania 1.69. The variations by race are noteworthy. In Pennsylvania, the locality which has the highest general average, the average number of persons per room ranges from 1.06 in the case of the households whose heads are white native-born of native father to 1.99 in the case of the South Italian households. This average for the South Italians in Pennsylvania is the highest for any race in any locality. The lowest average in any locality, 0.81, is found in the households in the Middle West whose heads are whites native-born of native father.

The averages in the Southwest vary from 1.16 persons per room in the households of the whites native-born of native father, to 1.70 reported by both Poles and Slovaks. In the South the foreign-born English have the lowest average number of persons per room, 1.20, and the Slovaks have the highest, 1.87.

The significance of these averages is greater when studied in connection with certain other figures taken from tables of this series.

locality.

In Pennsylvania, where the average apartment is considerably larger than in any other locality, the tendency toward large households results in the largest average number of persons per room in
