By 1846, Alta California had a Spanish-speaking population of under 10,000, tiny even compared to the sparse population of states in the rest of northern Mexico. The Californios consisted of about 800 families, mostly concentrated on large ranchos. About 1,300 American citizens and a very mixed group of about 500 Europeans, scattered mostly from Monterey to Sacramento, dominated trading as the Californios dominated ranching. In terms of adult males, the two groups were about equal, but the American citizens were more recent arrivals.
