Kern County in the south central part of the state makes up Region 5 of the California Migrant Education Program. Using the Migrant Student Record Transfer System as a data base, a study was conducted to examine the flow patterns of migrant students from, to and within each region and the state in 1977. Intrastate students dominated the California migrant student scene. In all, 1,568 intrastate migrant students entered a school within Region 5, as compared with 255 students entering from other states. Eighty-five percent of all intrastate students came from other schools in Kern County. Intrastate migrant students leaving schools in the region numbered 1,493 and 263 interstate students moved to other states. Data on a grade level basis showed 1,278 intrastate departures in grades K-6, 157 departures in grades 7-8, and 58 high school departures. Only 11 of the high school students moved to schools outside the region. Over 4,000 migrant students were reported as showing no movement during the year. When 1975, 1976 and 1977 records were compared for trend analysis, 1976 saw a 27% increase in the number of nonmobile students, and in 1977 an additional 5% was noted. Intrastate student movements increased from 88% to 92% in the three years. Tabular data with state, regional, and county breakdowns on intrastate and interstate migrant students include such information as numbers, origins, destinations and grade levels of students. (DS)
