Abstract

The purpose of the study is to find out the implications for the solution of population concentration in big cities by analyzing population concentration and its changing trend and iter-regional population migration pattern.
The study analyzed the degree of population concentration by using Gini concentration and Duncan Index in 16 cities including Seoul through 1987 to 1995.
@ES The findings of the study are as follows:
@EN 1. An analysis on the changing trend of population size showed that nationwide average population growth rate was 0.93% for 1987-1994. The average population growth rates by city were high in Sungnam, 6.85%, Suwon, 5.18 and Anyang, 5.15%. It
is
noted that Mokpo and Masan showed minus growth rates, 1.02% and 3.18% respectively.
2. Regarding the total population migration, the number of migratory population got higher in proportion to regional population in the order of Seoul, busan, Dageu and Inchon. The total population migration rates of big cities such as Seoul and
Busan
decreased whereas those of Inchon, Kwangju, Suwon, Sungnm and Anyang were over 50%. The nationwide rate of total population migration was over 20% for 1987-1992 and later it showed a decreasing trend recording 19.99% in 1993 and 19.77% in 1994.
3. Most of in-migration and out-migration were to outskirts of major cities and the next was Seoul city, which showed the fact that the distance was the important factor affecting the migration. In addition, the migration from metropolitan
cities
such
as Seoul, Busan, Daegu to the nearby satellite cities accounted for the largest part of total migration, which showed the fact that the broadening of three big cities are going on constantly.
4. Regarding the net migration, Seoul and Busan have recorded the minus nt migration rate since 1990 and 1989. The satellite cities near Seoul recorded the high net migration rate, which showed the intensive reversion. Mokpo, Pohang, Ulsan and
Masan
have recorded minus net migration rate since the truning point of 1990. The degree of population concentration to big cities was examined by using Duncan Index and Gini Concentration. Gini Concentration were 0.4658 in 1980. 0.5216 in 1985, 0.5744
in
1990 and 0.5842 in 1994. The period for which Gini concentration increased the greatest was from 1981 to 1985.
Point of 1990. The degree of population concentration to big cities was examined by using Duncan Index and Gini Concentration. Gini Concentration were 0.4658 in 1980. 0.5216 in 1985, 0.5744 in 1990 and 0.5842 in 1994. The period for which Gini
Concentration increased the greatest was from 1981 to 1985.
