The family number is taken by Kroeber (1925. p. 116) as the same as for the Yurok, i.e., 7.5. Loud obtained estimates for both house number and population for three villages. Site 45 gave 13.5 persons per house, site 67 gave 9, and site 112 gave 5. The average is slightly over 9, a figure which has no further significance than to indicate that the Yurok value of 7.5 may be applied safely to the Wiyot. With respect to Kroeber's principle of a one-third reduction in the number of houses the same considerations apply as with the Yurok data. There is nothing to indicate in the work of either Loud or Nomland and Kroeber that informants were not thinking in terms of inhabited houses rather than total deserted houses or house pits. Indeed we have in Loud's text three specific instances (nos. 7, 67, and Y) where the informant not only stated that the houses were occupied in the early days but also gave the names of the persons living in all of them. It is difficult to reconcile a one-third reduction with such data. In table 3 (pp. 94-96, herein) are given a few notes, gleaned mainly from Loud and supplemented from Merriam's list, which are of interest in determining the existence and population of certain villages. All villages are included the existence of which in approximately 1850 Loud regards as reasonably certain. To these are added several of Loud's doubtful sites, the validity of which has been confirmed by Merriam, plus five villages missed by Loud but discovered by Merriam. The house counts for those towns confirmed or discovered by Merriam have had to be estimated. The number has been taken rather uniformly as 2 or 3 in order to maintain as conservative a standard as possible. For 22 of the larger and better known sites Loud's informants gave an average of 6.5 houses. Hence an average of 3 for those whose names and locations only were known seems in no way excessive. In table 4 (p. 97, herein) are shown the best estimates for the Mad River and Humboldt Bay areas from Loud and Merriam and for the Eel River valley from Nomland and Kroeber. The total is 440. At 7.5 persons per house this means a population of 3,300 inhabitants for the Wiyot. The corresponding figure given by Kroeber in the Handbook (p. 116) is "perhaps 800 or not over 1,000." Loud states on page 302: "If asked to give an extreme figure for the native population ... the writer would say 1,500, and consider any higher figure pure folly." The present writer, however, stands by the figure of approximately 3,300, insofar as the estimate is based on ethnographic material.
