[Footnote 4: It must be observed in studying these figures, that farmers' wives and children, working at home, are not reported as gainfully occupied. But a widow or a spinster owner, if herself acting as the enterpriser, is reported as "occupied" in agriculture. The increasing number of such cases in the past generation in part explains the growing number and percentage of females in agriculture.

In part the change here noted results from increases in the population of towns and incorporated places from a little below 2500 to something about 2500. For example, if there were 2499 persons in a town in 1900 they would all be classified as rural; if in 1910 there were 2500 or more they would all be classified as urban.] [Footnote 7: Sec Vol. I, p. 225, and note 11.] [Footnote 8: See Vol. I, p. 206.] [Footnote 9: See Vol. I, p. 227, note, for figures on owners and farm laborers.] CHAPTER 26 PROBLEMS OF AGRICULTURAL ECONOMICS § 1.
