It has been well known that the family pjanning programme has a great deal with declining fertility in Korea. The present study was aimed to measure the impact of family planning program me on fertility level. The specific objectives are to overview the demographic changes ncluding fertility declining and to calculate actual number of birth averted during the last 20 years. The data used for the present study was collected from various sources such as service statistics of the government, survey and research reports, and other related papers. The tool used for calculation of birth prevention was "Standard Couple Years of Protection (SCYP) Method" developed by M Gorosh. The major findings are summarized as follows ; Total of family planning acceptors from 1962 to 1982 was 9,556,153. On the basis of this data, total of averted births was calculated for eachcontraceptive Method ; 1.Oral pills, total number of acceptors from 1968 to 1982 was 2.347,259. Estimated number of birth averted was 272 ,303 .70 and the Coefficient of births prevention per acceptor turned out to be 0.114 2.Condoms, total number of birth acceptors from 1962 to 1982 was 2,874,216. Estimated number of birth averted was 220,495.30 and the coefficient of births prevention per acceptor turned out to be 0.077. 3.IUD, total number of acceptors from 1962 to 1982 was 5,101 .650. Estimated number of birth averted was 1,377,584.76 and the coefficient of births prevention per acceptor turned out to be 0.270. 4.Vasectomy, total number of acceptors from 1962 to 1982 was 556,508. Estimated number of birth averted was 626 ,128 .80 and the coefficient of births prevention per acceptor turned out to be 1.125. 5.Tubaligation total number of birth acceptors from 1972 to 1982 was 1 210,775. Estimated number of birth averted was 1 ,117 679.00 and thecoefficient of birtlts prevention per acceptor turned nut to be 0.923. 6.Abortion, total number of acceptors from 1973 to 1982 was 465,525. Estimated number of birth averted was 355 ,283 .60 and the coefficient of births prevention per acceptor turned out to be 0.763.

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 inter-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. The findings of the study are as follows: 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, Daegu and Inchon. The total population migration rates of big cities such as Seoul and Busan decreased whereas those of Inchon, Kwangiu, Suwon, Sungnam 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 net 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 usig 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.
