The figures advanced here give the Pomo as a whole a population of 20,760 individuals. This is three times Kroeber's estimate but conforms to the general level found in this review of the Northwest California tribes.
POMO TOTAL ... 20,760
THE COAST MIWOK
According to the maps shown by Barrett (1908) and by Kroeber (1925), the Coast Miwok occupied an area of approximately 885 square miles in Marin and southern Sonoma counties. A projection of the Pomo value of 8.0 persons per square mile would give 7,080 for the Coast Miwok, a result which appears much too high.
A careful collection of former village sites through modern informants has never been possible, even at the beginning of the present century, because Marin County was infiltrated by the Spanish and the Indian life was thus disrupted at a very early date. Indeed the first recognizable Coast Miwok baptism was at San Francisco in 1783. Barrett and Kroeber have assembled, to be sure mainly from the tradition handed down to informants by their ancestors, a quite impressive list of villages. Barrett (1908, pp. 303-314) gives 36, and Kroeber on his map (1925, p. 274) shows 42. If we arbitrarily assigned a population of 100 each, we would have a total of approximately 4,000, probably somewhat too high a value. The difficulty is that we have no clear means of gauging the size of the typical Coast Miwok village, since no informants have been able to give a precise figure and since the terrain occupied by this tribe is different from that held by the Pomo to the north.
Even though the investigation of villages yields no very fruitful results, the Mission records for the Coast Miwok provide a quite adequate solution of the problem.
Unlike any other tribe north of San Francisco Bay the Coast Miwok were thoroughly and completely brought into the missions. Beginning, as indicated above in 1783, gentiles from the north shore were brought in small numbers to the Mission Dolores for conversion. In 1817 San Rafael was established, and within a few years the missionaries had made a clean sweep to the coasts of the bay and the ocean and had begun to penetrate north to the vicinity of Santa Rosa and Sebastopol. Meanwhile a considerable number of converts had been taken to San Jose, and subsequently some found their way to Sonoma. Fortunately we have the baptism records, or their equivalent, of all these missions.
Identification of the Coast Miwok can be made in most of the records (1) by the year and the location (e.g., the year 1817 at San Rafael); (2) by village names identical with or similar to those listed by Barrett and by Kroeber; (3) by linguistic affinities (such as the prefix echa- or the suffix -tamal); and (4) by subsidiary notes in the records indicating geographical location. Deleting all really doubtful cases we have the following numbers of baptisms
| San Francisco | 896 |
| San Rafael | 916 |
| Solano | 48 |
| San Jose | 162 |
