Many Natives of missions in the Southwestern region of what is presently U.S. territory and North Mexico fell victim to Euro-Asiatic diseases to which they had no immunity; such as those of the Pimería Alta and Baja California missions. However, demographic studies have shown that the Santa Barbara Channel Missions (Santa Inés, Santa Barbara, San Buenaventura, and La Purísima Concepción) and many other Alta California Missions do not exactly follow this trend. Though the missions were not free of epidemics, the censuses taken in the 1800s display that women and children had a much higher mortality rate than men. Diseases are not partial to gender or age, which meant that something outside of disease had a drastic effect on the Indian population in the missions.
