IN a volume recently issued, the United States Census Office has told us how many musicians and teachers of music (i. e. musicians who are principally teachers of music) there are in this country, where they are located, how many are men and how many are women, what are their ages, whether they were born in this country and whether their parents were born in this country. As the United States is practically the only country in the world for which such information is available, a brief review of the facts will be of interest, not only because they show the extent to which Americans earn their livelihood from the musical professions, but also because these facts show the intensity of the musical life of the country by indicating the number of persons the community supports in order to provide itself with music. The manner in which the information was secured by the Census Office requires a word of explanation. In April 1910, the census enumerators visited every residence in the country, and among other questions, asked what was the principal occupation of each person over ten years of age in the household. From these schedules was compiled the information about musicians and teachers of music now under discusssion. The enumerators were instructed to secure the principal occupation of each person; this meant that occupation from which the person obtained his principal means of support. One complication however arose in regard to women's occupations; if a woman was a housewife but in addition regularly earned money as a teacher of music, then she was classed as a teacher of music. The result of this procedure is that the Census tables include many women as teachers of music who very probably devoted only a small portion of their time to the teaching of music. In arranging the returns as to occupation in groups, the occupations of musician and teacher of music were placed in the general occupation division of "professional service." With the sole exception of the division of "domestic and personal service,"
