The main objective of this study is to conduct subnational population projections of Korea based on a multiregional cohort-component method. This objective is accomplished by: (i) establishing a viable framework to implement the multiregional cohort-component method with reference to the Markov chain model and Rogers' multiregional population projection model; (ii) applying the established framework to subnational population projections of Korea, 2005~2030. The main results are twofold. First, the proposed method turns out to be highly valid in a methodological sense, which is seen from a high level of coincidence between the estimated and the observed. Second, the projection results turn out to be highly useful in the sense that interregional migration flow matrices are resulted for projection periods. The projected migration flows are expected to provide invaluable information for an understanding of future population change and for a formulation of policy alternatives. This study is strongly inspired by the multiregional perspective emphasizing the evolution of multiple regional populations interconnected by interregional migration flows rather than the overall national change.

There was a large reform in administrative districts during 1990-95, which might influence the estimates of migration according to the definition of migration. An indirect method has been worked out in this paper to measure the influence of the district reforms on migration estimation and to provide more accurate recent trend of migration. The district reform during 1950-95 tended to decrease the estimate of total migrants and influenced substantially the estimates of migrants between urban and rural. When the influences of district rewarm were removed, it was found that total migrations increased by 8.5%, between two periods 1985-'90 and 1990-'95, and the net migrants in the rural areas reduced drastically. It was also found that the change in migration trend between urban and rural was no more a local but a nation wide phenomenon.

There was a rapid population change accompanied with changes in population structure recently in Korea. The changes were nationwide though greater in rural, where the population decreased steeply, through the internal migration from rural to urban. There, in the structure of Gun's population, severely distorted features have been shown in the study. Also, the structure differ greatly by Gun. It indicated that the rural problems were much more serious than anticipated when analyzed generally. It tells us that we should consider the problems related with different population structure in developing the programs for the rural.

Urban centers have been recognized as problem regions so far. However, urban centers of metropolises take a new aspect in recent years as much as the negative influence of gentrification becomes a social issue. This paper analyzes the declining trend of urban centers in six metropolises - Seoul, Busan, Daegu, Incheon, Gwangju and Daejun from 1995 to 2010. As results of analysis, it is identified that the urban centers' shrinkage got moderated recently in the metropolises, even though their resurgence is not evident. Especially it is difficult to say longer that Jongro-Gu and Jung-Gu of Seoul are declining urban centers. Easing shrinkage is most outstanding in Jung-Gu, Daegu among local metropolises. Nevertheless, a serious obstacle such as high price of housing is in the process of obvious resurgence of urban center differently from the United States, Europe and Japan.

Analysis based on the Korea Labor and Income Panel Survey data reveals that earnings have become less volatile since the exchange rate crisis, while they have become more unequal. The reduction in measured earnings volatility is not explained by changes in the composition of various economic/demographic groups but accounted for by within-group reduction in the measured earnings volatility, which in turn is attributed to the reduced earnings mobility during the sample period. It is also found that measured earnings volatility is countercyclical and earnings changes are symmetric even during recessions.

In this study, labor force projections are made in order to examine the process and magnitude of labor shortage caused by population ageing in Korea. Starting from theoretical review and analysis of population projection data, this study presents that serious transitions of labor market are expected to begin between 2020 and 2030. This study shows even in case of encouraging higher labor participation, labor shortage cannot be offset but only delay and alleviate effects of population ageing. Finally, this study points out some important implications of labor policy including sensitive social and political issues which should be considered.

가구는 주택과 내구소비재 구입의 단위가 되기 때문에 장래의 가구수에 대한 자료는 정부가 주택정책을 수립하거나, 기업체가 가전제품이나 가구를 생산하는 장기 계획을 짜는 데 필요불가결한 정보 중 하나이다. 우리 나라는 현재 심각한 주택난을 겪고 있으며 이 주택난은 가구의 급증과 떼어 놓고 생각할 수 없다. 최근 우리 나라의 주택난 해소에 대한 합리적인 대책을 수립하자면 정확하고 상세한 가구추계가 요청된다. 그리고 경제적으로 취약한 계층인 노년인구가 급증하고 있는 것과 관련해서 노인가구의 증가가 예상되고 있는데 이들을 대상으로 하는 각종 사회복지정책의 수립에는 전반적인 가구구조와 노인가구에 관한 정확한 예측이 절실하게 요청되고 있다. 본 연구는 단순한 가구수 추계뿐만 아니라 가구구조 및 혼인상태별로 다양하게 가구수를 추계할 수 있는 비교적 간편하면서도 신뢰성을 인정받고 있는 고노(Kono)의 확장된 가구주율법을 사용하고 최근의 센서스 자료를 활용하여 가구수 추계를 실시하였다. 이 연구에서는 지난 30년간의 가구구조의 변동을 분석하고 1990년 이후 10년간 우리 나라의 시·도별 가구수를 전망하며, 노인가구를 위시한 가구형태별, 가구규모 및 혼인상태별로 가구수를 추계하고 있다. 아무쪼록 이 연구결과가 지방자치화에 따른 지역 주택정책 수립 및 노인복지 등 각종 사회복지정책의 수립에 필요한 자료로써 널리 활용되기를 바란다.

This study attempts to predict the changes in the spatial distribution of occupational employment in Korea by applying Markov Chain Model. For the purpose we analyze the job-related migration pattern and estimate the transition probability with the last six years job-related migration data. By applying the Chapman-Kolmogorov equation based on the transition probability, we predict the changes in the spatial distribution of occupational employment for the next ten years. The result reveals that the employment of professional jobs is predicted to increase at every city and region except Seoul, while the employment of elementary labor jobs is predicted to increase slightly in Seoul. In particular, Gangwon-do and Chuncheongdo are predicted to increase in the employment of all occupational jobs.
