Abstract
The purpose of this research seeks to annalyze the spatial variations in age structure which have been shown to exist within the study area, Chungcheong bukdo in Korea from 1966 to 1975 inclusive. In this study it is desired to use the Age Structure Index developed by Coulson in order to describe the age structure of each of 425 tarcts that comprise the tracted portion of Chungcheong bukdo. The mechanics of computing the Age Structure Index are found in the equation describing a linear least squares trend line: y=a+ bx. For each census tract, the percentage of the population in each age group(y) was plotted against the middle age of each age group (x). The a is a constant representing the value of y, when x equals zero. The b is the regression coefficient and is a measure of the angle of the slope of the least squares trend line. Thus the value of b is the Age Structure Index for each census tract. 2. The major results of this investigation can be summarized as follows: The spatial distributions of age structures in Chungcheong bukdo in 1966, 1970, and 1975 are far from random. They have exhibited great regularity with the younger age structures in the urban regions and a sharp decline to the older age structures out in all directions towards rural regions. From northeastern region through southwestern region the younger age structures have been changed into the older age structures.
