Old Colony Mennonites in Mexico appear to demonstrate natural fertility, use no form of artificial birth control, and are apparently not attempting to limit family size. The resulting fertility is nearly as high as that of the Hutterites, although the Mennonites lack the communal economic system of the latter group. Most Mennonites in Mexico migrated from Canada in the 1920s and the largest single settlement, called the Manitoba Colony, is 1 of 4 in the state of Chihuahua. A partial census in 1967 obtained data from 38% of the Mennonite households. Family size in the sample was close to that of a local survey taken in the same year. Available church records matched with census forms permitted verification of and corrections to 560 female reproductive histories. The median number of livebirths to women over age 45 was 9.5 compared with 10.4 in the Hutterite community. Age- specific marital fertility rates and birth intervals closely resembled those of the Hutterites.
