This paper attempts to clarify the migration pattern by sex and age classes in Aichi Prefecture (Fig. 1), using the migration data in 1988 collected by the Bureau of Statistics, Aichi prefectural office. These data consist of origin and destination matrices between 103 areas classified by sex (male and female) and age classes (0-14, 15-19, 20-29, 30-64 and 65 and over).<br>Three mode factor analysis is conducted to find the migration structure of the complex O-D patterns (Fig. 3). First, as a result of factor analysis on destinated areas based upon Equations 2 to 5, eight factors are derived (Table 1). Five factors show the movement in the marginal part in Nagoya-shi and its surrounding areas, and two factors show the movement within the urban areas in Nishimikawa region, central part in the prefecture, One more factor shows the movement around Komaki-shi located in the northern part of Nagoya-shi.<br>Second, as a result of factor analysis on origins based upon Equations 6 to 11, nine factors are derived (Table 2). Two factors show the movement in the central part in Nagoya-shi, four factors in the marginal part in Nagoya-shi and its surrounding areas, one factor in the areas around Komaki-shi and two factors in the Nishimikawa region.<br>Finally, as a result of factor analysis based upon sex and age classes, three factors are derived: the factor indicating the migration of male infant, boys and middle-aged generations, the factor indicating the migration of female infant, boys, young and middle-aged generations and the factor indicating the migration of female old-aged generation and young male generation (Table 3). Fig. 6 shows the migration pattern of each factor based upon the core matrix calculated by Equations 18 and 19. All three factors indicate the movement from the central part to the surrounding areas. However, the directions of movement are quite different by each factor. For the infant, boys and middle-aged generations, the migration from the central part to the east of the city is dominant. For the young generation, the migration from the central part to the southwest and south of the city is prevailing. The migration by the old-aged generation is strong between the central part and the east and southwest of the city.
