The Employment Development Department's Migrant Services Section provides temporary housing at reasonable cost for migrant farmworkers and their families by contracting with local government agencies to manage programs of housing construction, operation and maintenance. Since 1965 migrant housing projects have been constructed at 26 locations in 14 agricultural counties throughout California. This temporary housing, which is available for up to 180 days per year to migrant families while they are employed in agriculture, range in size from 50 to 125 units per center. In 1977 services were provided to 2,360 families whose members constituted a work force of 6,381; the average family size was 5.2 persons; the average annual family income was $5,140; 82.5% were Mexicans while 15.3% were Mexican Americans; 26.4% were from Texas while 24.4% were from within California; the average length of stay was 132 days; and 27.8% were between 22 and 44 years of age. Covering January through December 1977, this report presents tabular data on the characteristics of the migrant families occupying these housing centers. Given by center, the data pertain to: center occupancy; family size; age of family members; age of male and female family members; annual income by center and by family size; ethnic background; school years completed by persons 18 years and over; number of families by length of stay, total days and average stay; family home base; operation and peak occupancy dates.
