This coverage report is on an Alternative Enumeration (AE) carried-out for the Ethnographic Evaluation of the Behavioral Causes of Undercount Study, a project of the Undercount Behavioral Research Group of the Bureau of the Census. The AE is one of ten projects selected nationally to study undercount behavior of Hispanic populations in the United States and Puerto Rico.

The population in the ethnographic site is primarily made up of Mexican and Mexican American farm worker households who reside in a Californian farming community on a permanent basis. These proletariat households have no or few ties to the peasant economy in Mexico. In other words, the households are not comprised of peasant migrants who come to mind when we think of farm workers in California. farm worker householders at the site do not pack up and leave when the harvest is poor or over, do not move to another harvest site nor do they return to a home base in Mexico. This California community is their home. However, some temporary household members, called arrimados in Spanish and who are related to the householder and spouse through kinship, reside locally during the lettuce harvest and return to Mexico after the season.
