The ratios of Caesarean Section (C-section) Deliveries to deliveries have steadily increased since 1990’s in Japan. To find out the reasons, the socio-economic factors behind the rate of C-section deliveries should be determined in addition to a delivery’s risk factors. Then, regressions of the Socio-Economic factors and the delivery’s risk factors on the C-section delivery rate are conducted. V ital Statistics, and the Report on Survey of Medical Care Institutions by MHW have mainly been used to construct the regression data set for the C-section rates and mothers’ delivery risks at prefectural level, and date on the socio-economic factors have been constructed by prefectural Socio-Economic Statistics. The 2-Stage Least Squares’ estimation results that were obtained are as follows. The mother’s opportunity cost (as a Socio-Economic factor) negatively affects C-section delivery rate; this is unexpected The average number of visits for prenatal checkup (as a Socio-economic factor) positively affects the rate, and accessibility to Ob-Gyn medical institutions (as a Socio-economic factor) has a negative effect. The mother’s age at the time of delivery (as a Socio-economic Factor) positively affects the rate, and the average weight of neonates (as a delivery risks factor) negatively affects it, as expected.
