Using data taken from the Migrant Student Record Transfer System, a study was undertaken to examine migrant student movement patterns for Region 1 of California's Migrant Education Program which includes eight counties located along the Pacific coast between Los Angeles and San Francisco. In 1977, 490 students entered Region 1 from another state; 74% were elementary school students. Monterey, Santa Clara, and San Benito were the major receiving counties. Another 490 migrant students moved to other states; 68% left Monterey and Santa Clara counties. Within the region 8,191 intrastate students entered schools and 8,156 students departed. Ninety-one percent of all departing students entered other schools in the same county. Over 16,000 students showed no movement at all. A summary of 1975 and 1976 inter- and intraregional movements showed substantial increases in both movement within the region and in the number of nonmobile students. Because of these trends, the problem facing educators is to deal with the interruption of services and to assist students in catching up on information lost due to their moves. Tabular data is given on numbers, origins and destinations of interstate students. Intrastate figures include regional movement, grade level breakdowns, origins, destinations, and no movement at all statistics. Data on student movement in 1975 and 1976 are also included. (DS)
