TABLE 2.-Households studied, by general nativity and race of head of household.

Upon reference to the table preceding, it is seen that of the total number of households studied 1,139, or 6.6 per cent, were those of heads who were native-born white persons of native fathers; 727, or 4.2 per cent, were of heads of native birth but of foreign father; and 148, or 0.9 per cent, were of heads who were native-born negroes. These classes of households, together with those the heads of which were foreign-born English, German, Irish, Welsh, and Scotch industrial workers, were selected to afford a comparison, as stated above, with wage-earners of southern and eastern Europe engaged in the same industries and occupations. The remaining households, having been selected on the basis of the numerical importance of the several races in the different industries studied, indicate the relative extent to which members of the several races were employed in the mines and manufacturing establishments of the United States. In this respect the Poles outrank all other races of recent immigration, 12.3 per cent of the total number of households studied representing this race. The South Italians and Slovaks are next in order; of the total number of households, 8.9 per cent are of the former and 7.7 per cent of the latter race. As a matter of fact, the Poles and South Italians are employed in practically all branches of mining and manufacturing enterprise. The Slovaks are not so extensively engaged as the Poles and South Italians, but in those industries in which the Slovaks are principally employed, such as bituminous and anthracite coal mining and the iron and steel plants, they appear in larger numbers than the other two races. After the Slovaks, the Germans, Magyars, Lithuanians, Hebrews, Irish, North Italians, Croatians, Ruthenians, and French Canadians form the largest proportions of the body of foreign-born wage-earners who are heads of households. The heads of households of other races occur

in comparatively small numbers in different industries or, as in the case of the Brava textile operatives in New England, the Cuban cigar makers in Tampa and New Orleans, or the Mexican miners in the Southwest, are representative of only one industry or of a certain geographical area in which the industry is located.
