To clarify the measures for increasing permanent residents in rural areas, we evaluated the population migration of the young, by analyzing the net migration rate until the young group aged 15-19 years becomes 25-29 years old after 10 years in 44 municipalities in Kyoto Prefecture. This period correspond that of employment, advancing to the next stage of education, and marriage. The following results were obtained. 1) The general trend of “moving from rural areas to cities” was more predominant in females than in males. 2) The influences of the geographical condition of municipalities (distance from Kyoto City) on population migration have been gradually decreasing. 3) A significant correlation was observed between modernization of the sewage system and the migration of the young population (p<0.05 in the males and p<0.01 in the females). 4) In the females, even after excluding the influences of the geographical condition, a significant correlation was observed between modernization of the sewage system and population migration (p<0.05). Observation 2) was obtained by the following procedure. First, scatter diagrams were produced by plotting population migration (migration rate) in each period (1965-1975, 1970-1980, …, 1990-2000) on the y-axis and the geographical condition of each municipality (distance from Kyoto City) on the x-axis. Second, the linear function, y=ax+b and the logarithmic function, y=a · ln(x)+b were applied to each scatter diagram. Observation 4) was obtained using the partial correlation coefficient, not the correlation coefficient.
