GENERAL EXPLANATION OF TABLES. Persons of native birth have been divided into two general groups and further subdivided under each of the two, as follows: 1. Native-born of native father. Persons under this group are classified as White, Negro, Indian, Chinese, Hindu, Japanese, and Korean. 2. Native-born of foreign father. Persons under this group are classified according to race of father in all tables where the data were secured for households, and according to country of birth of father in all tables where the data were secured for employees. Where classification is by race of father the classification used for several years by the United States Bureau of Immigration and Naturalization is followed. Persons of foreign birth are classified according to race (or people). The classification of the United States Bureau of Immigration and Naturalization is followed. In the study of households information is presented 1. By general nativity and race of the "individual" in all tables which show facts which are personal in their nature, such as English speaking, occupation, or conjugal condition. 2. By general nativity and race of "head of family" in tables concerned with family matters-for example, family income. 3. By general nativity and race of "head of household" in all tables dealing with living conditions, among which are tables showing the composition of the household and the number of persons per room and per sleeping room. The distinction which has been made throughout this study between "family" and "household" is dependent upon the use of the term "apartment.' An "apartment" is a room or rooms within which all the usual daily processes of living, namely, cooking, eating, and sleeping, are carried on by the occupants. According to this definition an apartment may be, for example, a whole house; or it may be a single room of what was originally intended as an apartment; or it may be a corner of a wareroom or the back of a storeroom partitioned off and set aside for household uses. Two or more groups of occupants with distinctly separate money interests frequently rent a number of rooms jointly, occupying certain rooms separately but sharing one or more, usually the kitchen, or kitchen and living room. Under these conditions neither the rooms used by the one group of occupants. nor those used by the other can be considered an apartment, since the room used in common must in such case be considered a room in each apartment and thus be counted twice. Where these conditions have been encountered the entire number of rooms has been considered one apartment. The "household" includes all persons living within an apartment hom The household may consist of one or m boarders or lodgers; or it may consis together, no family included; or it ma tions of families, "groups," and board The term "family" as used througho to the immediate family composed of Groups of persons among whom none considered families.
