TABLE 485.-Households studied, by general nativity and race of head of household.

The proportion of households studied as shown by the above table is indicative of the relative numerical importance of the different classes of households in the community; the households whose heads were native-born, as well as those whose heads were native-born of foreign father, were studied in numbers sufficient only for purposes of comparison with the households the heads of which were foreign-born. The following table shows, by general nativity and race of head of household, persons in households studied and persons for whom detailed information was secured:

RACIAL DISPLACEMENTS.

History of immigration to Community D-Period of residence in the United States of foreign-born employees and members of their households-Racial classification of employees at the present time-Methods of securing recent immigrants-[Text Tables 490 to 492 and General Tables 265 and 266].

HISTORY OF IMMIGRATION TO COMMUNITY D.

Immigration to Community D began in 1901, when the first steel plant was erected. A large number of South Italians were employed at that time, but as soon as the construction work was completed they all left the community. The first employees in the steel mills were principally Poles, and throughout the entire industrial life of the community the Poles have been in the majority among the workers. During the first five years that the steel plants were running, large numbers of German and Irish immigrants were given employment, but of late years the proportion of these races has steadily decreased, while Magyars, Croatians, Slovaks, and Servians have come in and taken their places.

PERIOD OF RESIDENCE IN THE UNITED STATES OF FOREIGN-BORN EMPLOYEES AND MEMBERS OF THEIR HOUSEHOLDS.

The following table shows, by race, the percentage of foreign-born male iron and steel workers studied who had been in the United States each specified number of years. While the period of residence in the United States is not necessarily the same as that for the locality, it is believed that the two periods closely approximate each other: TABLE 490.-Per cent of foreign-born male employees in the United States each specified number of years, by race.

[By years in the United States is meant years since first arrival in the United States. No deduction is made for time spent abroad. This table includes only races with 40 or more males reporting. The total, however, is for all foreign-born.]
