Native California Population, according to Cook 1978.

Estimates of the Population of Native California have varied substantially, both with respect to its pre-contact levels and for changes during subsequent periods.

Pre-Contact Estimates

Figures for the Native Californian population prior to European entry into the region have been based on a number of different sources, including:

• estimates of the numbers of individuals or households, made by early explorers, missionaries, and travelers;
• analysis of Franciscan mission records (births, baptisms, deaths, and total numbers of neophytes at particular periods);
• counts of villages that are known from historic, ethnographic, or archaeological records, multiplied by estimates of the average number of inhabitants per village;
• ecological estimates of the regional human carrying capacity, given aboriginal technologies and economies;
• population density extrapolations from better-documented regions to less well known ones; and
• extrapolations back from historic censuses, using estimated rates of population decrease

Few analysts would claim that these methods have yielded precise figures. Estimates by different analysts have commonly diverged by a factor of two or more. The Spanish Missions in California (more simply referred to as the California Missions) comprise a series of religious outposts established by Spanish Catholic Dominicans, Jesuits, and Franciscans, to spread the Christian doctrine among the local Native Americans. ... Carrying capacity is the population level that can be supported for an organism, given the quantity of food, habitat, water and other life infrastructure present. ...

Stephen Powers (1872:307) initially proposed an estimate of 1,520,000 for the pre-contact population of the state. He subsequently reduced this figure to 705,000 (Powers 1874:308).

C. Hart Merriam (1905) offered the first detailed analysis, based on mission records and extrapolation to non-missionized areas. His estimate for the state as a whole was 260,000. Clinton Hart Merriam (December 5, 1855-March 19, 1942) was an American zoologist and ornithologist. ...

Alfred L. Kroeber (1925:880-891) made a detailed re-analysis, both for the state as a whole and for the individual ethnolinguistic groups within it. He reduced Merriam's figure by about half, to 133,000 Native Californians in 1770. Alfred Louis Kroeber Alfred Louis Kroeber (June 11, 1876–October 5, 1960) was one of the most influential figures in American anthropology in the first half of the twentieth century. ...

Martin A. Baumhoff (1963) used an ecological evaluation of carrying capacity to propose an aboriginal population of 350,000.

Sherburne F. Cook was the most persistent and painstaking student of the problem, examining in detail both pre-contact estimates and the history of demographic decline during mission and post-mission periods. Initially, in 1943, Cook (1976a:161-194) arrived at a figure only 7% higher than the one previously suggested by Kroeber: 133,550 (excluding the Modoc, Northern Paiute, Washoe, Owens Valley Paiute, and Colorado River Yumans). Subsequently, Cook (1976b, 1978) raised his estimate to 310,000.

Some scholars now believe that waves of epidemic diseases reached California well in advance of the arrival of the Franciscans in 1769 (Preston 1996, 2002). If correct, this may imply that population estimates using the beginning of the mission period as a baseline have substantially underestimated the state's pre-Columbian population. In epidemiology, an epidemic (from Greek epi- upon + demos people) is a disease that appears as new cases in a given human population, during a given period, at a rate that substantially exceeds what is expected, based on recent experience (the number of new cases in the population during a... The term Pre-Columbian is used to refer to the cultures of the New World in the era before significant European influence. ...

Post-Contact Changes

The decline of Native Californian populations during the late eighteenth and nineteenth centuries was investigated in most detail by Cook (1976a, 1976b, 1978. He assessed the relative importance of the various sources of the decline, including Old World epidemic diseases, violence, nutritional changes, and cultural shock. Declines tended to be steepest in the areas directly affected by the missions and the Gold Rush.) Other studies have addressed the changes that occurred within individual regions or ethnolinguistic groups. The California Gold Rush (1848-1855) was the first world-class gold rush. ...

The Native California population reached its nadir of around 25,000 at the end of the nineteenth century. Based on Kroeber's estimate of 133,000 people in 1770, this would represent a decrease of more than 80%. Using Cook's revised figure, it would constitute a decline of more than 90%. The population subsequently rose substantially throughout the twentieth century. This recovery may represent both true demographic growth and changing patterns in ethnic self-description.

In the twenty-first century, after more than eight generations of close interaction between Native Californians and individuals of European, Asian, African, and other Native American descent, there can be little objective basis for quantifying the Native Californian component within the state's population. However, reservation rolls and census self-descriptions provide some information.

Estimates by Ethnolinguistic Groups

More detailed population estimates for the individual ethnolinguistic groups within the state are summarized in the articles on those groups.
