"Do poor economies grow faster than rich ones? This...economic question...is analyzed in this paper using two regional data sets: 47 prefectures in Japan and 48 states of the United States. We find clear evidence of convergence in both countries: poor prefectures and states grow faster. We also find that there is intraregional as well as interregional convergence. We analyze the cross-sectional standard deviation across prefectures and states.... Finally we study the determinants of the rates of regional in-migration.... We find little evidence in favor of the argument that population movements are the reason why we find convergence across economies.", (excerpt)

"This paper aims to study the pattern of urbanization and the evolution of [the] relationship between rural-urban migration and the degree of economic development taking Gross National Product...into consideration. Intercensal age-specific rural net out-migration rates are also estimated from [tabulations] of the proportion of rural population of India by age through a recently developed procedure based on generalized stable population by Stupp (1989). A comparative study is also made between [the] survival column of India with a developed nation like Japan.", (excerpt)

"This paper examined the relationship between locus of control and such variables as unmarried woman's sexual activity, wife's experience of premarital conception, female marriage probability, post marital contraception and first-conception probability in present-day Japan...[using data from the 1987] Ninth Japanese National Fertility Survey....[The findings] contradict the general prediction that the internal locus of control is associated with well-planned behaviours...."

"This article compares the Korean minorities in China and Japan in their differential levels of cultural autonomy and ethnic identity....In explaining the differential levels of ethnicity between the two Korean minority groups, this paper focuses on the basic differences in minority policy between the two countries; the difference in the context of migration; the existence or absence of a territorial base; and the differential levels of influence from Korea.", (excerpt)

"This paper investigates the spatio-temporal dynamics of Japan's birth rates in the post-World War II period. The results of our analyses suggest that the spatial manifestations of the tail end of the demographic transition in Japan have been influenced by cyclical fluctuations, with a boom which produced a reversal of the traditional rural-urban birth rate differentials. Our analyses implement the research philosophy and the techniques of... Expansion Methodology." (SUMMARY IN JPN), (excerpt)

"This paper estimates the value of [natural fertility] and [the degree of parity-specific fertility control] in rural Tokugawa Japan mainly using [the Coale-Trussell model]. What we gained through this analysis is 1) the level of natural fertility in rural Tokugawa Japan was very low compared to the pre-transition level of England, [and] 2) in spite of this low level fertility, parity-specific fertility control was not practiced.... We can say that rural Tokugawa Japan since the second half of [the] seventeenth-century was in a 'natural fertility regime'...." (SUMMARY IN ENG), (excerpt)

"In this paper the impacts of structural changes in local industries on interregional gross migration in Japan for 1974-85 are empirically examined. Structural changes in local industries, which are represented by a simple index of local employment growth dispersion across sectors, induce interregional migration, as well as intraregional migration. The estimation results with pooled data support this hypothesis. The impacts of structural changes in local industries are different across gross migration flows (rural-urban, urban-rural, urban-urban, and rural-rural migration), as are the impacts of other determinants of migration such as earnings differentials, aggregate employment growth, national unemployment, distance, and age structure.", (excerpt)

"This article presents a new method for decomposing age distribution changes into changes in the number of births and changes in age-specific rates of mortality and migration. The method is developed on the basis of the equation for the age-specific growth rate proposed by Horiuchi and Preston (1988). Using this method, it is shown that the increase in the proportion of women in Japan during 1970-1980 is mainly due to the reduction of mortality, particularly at old ages. The results lend support to the proposed idea that the pattern of age structure changes in developed countries is now shifting from fertility-dominated to mortality-dominated ageing." This is a revised version of a paper originally presented at the 1989 Annual Meeting of the Population Association of America., (excerpt)

"This paper examined the validity of a Butz-Ward-type model by applying it to trends in Japan's fertility rates from 1968 to 1986. Most of the existing studies on the Butz-Ward model used total fertility rates as the dependent variable. As the Butz-Ward model is concerned with couples' fertility behaviors, [the author uses]...total marital fertility rates. We first calculated total marital fertility rates (TMFR) from 1968 to 1986 by using data of Japan's National Fertility Surveys.... As a result of the auto-regression analysis of TMFR, we found a statistically significant negative effect of a rise in employed wife's wage rate as was expected. As for the timing indices, the third birth timing index was significantly positively affected by an increase in husband's income when his wife was employed, while the third birth was likely to be delayed by a rise in employed wife's wage rate."

"This paper carried out a multivariate hazard analysis of the first, second and third birth timings by applying [a] log-logistic model. The results are as follows: (1) When wives are employed, the first, second and third birth hazards are all smaller than others....(2) Coresiding with couple's parents is likely to raise the first, second and third birth hazards irrespective of wife's employment status; (3) Wives with tertiary level education are accompanied by a smaller first birth hazard compared with others, while wife's educational attainment does not show any effect on the second and third birth hazards; (4) White-collar husbands are associated with a smaller first birth hazard when their wife is employed; (5) Even after controlling for several background variables, the first, second and third birth timings were accelerated in the cohorts of the late 1960s. This result suggests that the birth timing change in the late 1960s was caused by some heterogeneity which is not considered in this study."

"The purpose of the present paper is to review the recent trends in population age structure in Japan and to assess the demographic determinants of those trends relating to the impacts of fertility and mortality change on aging." A decline in cohort mortality and a significant decrease in the birth rate since 1973 have increased the proportion of the aged population. (SUMMARY IN ENG), (excerpt)

"This paper constructs and estimates a simple model of Japanese completed fertility. The analytical model shows that as a woman's lifetime wage rises, there is a decline in average 'quality' per child, but the effect on the quantity of children is ambiguous. Estimation of the model with rare household level data shows that increases in the husband's permanent income raises completed fertility for high income couples, but lowers fertility for the low income. If the wife's education is an appropriate instrument for her lifetime wage, then a rise in the wife's lifetime wage appears to lower her demand for children.", (excerpt)

Analysis of gonadotropin secretion patterns throughout the menstrual cycle revealed a complex rhythm. Especially at 1-3 hour intervals this was seen, with a frequency that was dependent on the phase of the menstrual cycle. There is little information available concerning the role of plasma luteinizing hormone-releasing hormone (LHRH) in the regulation of donadotropin secretion in amenorrheic and postmenopausal women. In this paper, the authors present the results of a detailed investigation into the secretory pattern of LH, follicle stimulating hormone, and LHRH in normal women with a normal menstrual cycle, amenorrheic women, and postmenopausal women.

"The present paper is a comparative analysis of part of the survey of the elderly population conducted in the Jingan District of Shanghai in October 1987, and part of the survey on the social welfare (the actual living conditions) of the elderly in the special districts of Tokyo, with a view to finding the similarities and differences between the two localities.... The purpose...[is] to pinpoint certain measures adopted by Japan with respect to the aging issue that might be of interest to China." Consideration is given to marital status, family structure, number of children, health status, education, and employment. The role of family support of the elderly receives particular attention., (excerpt)

Tracing the origin of political economy as a class-science, this paper focuses on the political economy of population growth. Exposing the limitations of Malthusian ideas and their invalidity even for the capitalist economies, it discusses the subsequent revival of the Malthusian model during the period of de-colonization and the misinterpretation of the relationship between population growth and development in the developing and developed countries. Taking India, China, and Japan as some case studies, the paper examines the relationship between birth rate levels and some correlates. It elaborates on the Indian experience, emphasizing the association of population growth with poverty and unemployment and lays bare some of the hidden causes of these phenomena. The authors examine some interstate variations in India and identify constraints and prospects of the existing population policy. The paper proposes outlines of a democratic population policy as an integral part of India's development strategy which should recognize human beings not simply as consumers but also as producers of material values. It pleads for 1) restructuring of property relations; 2) bringing down the mortality rates and raising of the literacy levels, especially among females; and 3) improving nutritional levels, as prerequisites for bringing down birth rates.

This paper reviews recent new trends in population structure in the world and its major regions in order to access the determinants of those trends and explore issues regarding the recent and projected changes in the age structure of population and the relationships of those changes to social and economic development. In particular, the paper compares the change in age structure projected by the Population Division of the UN Secretariat in its most recent 3 series--namely, those completed in 1984, 1986, and 1988. By and large, the most recent UN assessment projects that a larger proportion of the world population will be aged 60 and over in 2000 and 2025 than was previously estimated. Those changes in projections can be observed for the world and for the more developed countries as a whole, and for the regions of Africa, Latin America, Northern America, East Asia, Europe, and Oceania. While the recommendations of the International Conference on Population called attention to the importance of changes in population structure, this paper recommends urgent government action in planning social programs for the aged because of the greater eminence of population aging in many settings. The case of Japan is used to illustrate the growing importance of increases in life expectancy as a determinant of age structure changes (in relation to fertility decline), a point that is reinforced through a cruder decomposition of UN estimates and projections for several European countries.

The 1st section of this paper, using a method to decompose a change in the total marital fertility rate into the quantum and tempo effects, confirmed the major effect of birth timing on the 1970s trends in the total marital fertility rate based on the pooled data of the 8th and 9th Japanese National Fertility Surveys of 1982 and 1987, respectively. In the next section, proportional hazards model analyses of the 1st, 2nd, and 3rd birth functions for the pooled data made it clear that the 1st and 2nd birth intervals among the marriage cohorts since the end of the 1960s were shorter than those in the early 1960s even after having controlled for other variables. Given that 1 conception or more can occur during a birth interval, proportional hazards model analyses were again utilized to examine the effects of various variables on the time elapsed since marriage and the 1st conception, the time between the end of the 1st pregnancy and the 2nd conception, and the time between the end of the 2nd pregnancy and the 3rd conception. The authors found that the 1st-conception probability of the marriage cohorts since the late 1960s was smaller than that of predecessors, while the 2nd-conception probability was not affected by marriage cohort. In the last section, a logistic regression analysis of the probability of induced abortion showed that the probability of aborting a 2nd pregnancy decreased in the 1970s compared with that in the early 1960s. When a proportional hazards model analysis of the 2nd birth function was applied after omitting those cases where the 1st pregnancy did not result in birth and/or the 2nd pregnancy was aborted, the strong effect of marriage cohort on the 2nd birth probability was substantially diluted. These facts suggest that the shortened 2nd birth interval in the 1970s was partly caused by the shrinking probability of aborting a 2nd pregnancy in this period.

"The aim of this paper is to illuminate basic characteristics of metropolitan areas in Japan. [The authors] first delineate the boundaries of ninety-eight Japanese metropolitan areas based on the concept of cut-off point on the P-M curve the idea of which was originally developed by Ogawa in 1957. Secondly, [they] carry out empirical analyses on spatial structure and growth patterns of those metropolitan areas by use of 1960 and 1975 data." The results indicate that the population share of central cities declined from 1960 to 1975., (excerpt)

The present study is part of a larger project on the formal demographic analysis of Japanese fertility. It deals with the most elusive aspect of fertility, that is the tempo of fertility. The temporal aspect of fertility, particularly in terms of cohort fertility framework with speical reference to parity of women, has been emphasized by Whelpton and Ryder, but in the Japanese demography there have scarcely been studies of this aspect, probably due to lack of interest. In very recent years, however, interest has grown, reflecting the need for more accurate fertility projections in the future in connection with population projections. The present study is an application of life table techniques to explore the temporal aspect of fertility in Japan. 2 methods have been used. One is the age-marriage-parity specific net reproduction rate tables, which were first constructed by the senior author of this paper. The other is by Professor Chin Long Chiang at the University of California, Berkely. In the application of the former type, net reproduction rate tables were constructed for 3 dates -- 1970-71, 1975-76, and 1980-81. Through this method, it was demonstrated that recent fertility for the period 1980-81 was reduced, partly because of the decline in fertility in live-birth order of 1 and 2 among the relatively young ages up to 25 years old. On the other hand, for the ages up to 30 years old, some catching-up mechanisms took place. The 2nd method is by Chiang's new approach to the fertility table. According to his method, which was included in his new book entitled Life Tables and Its Applications, parity-oriented fertility tables have been constructed for the Japanese females for every year from 1971 through 1983, both inclusive. In these cases, denominator is for year z while numerator is concerned with yea z + 1. This method is particularly interesting since it can calculate waiting time for childbearing until the completion of family formation. Some of the findings indicated: 1) recent increases in both parity progession ratio and parity-specific fertility rate in low parity augur a future increase in fertility in the period measure in the near future; and 2) a shortening of the waiting time until the completion of family formation around 1981 and then the recovery of its lengthening in the years 1982 and 1983 suggest a recent trend of lengthening actual reproductive period which definitely contributes to an increase in fertility.

This paper clarifies the child-sex effects on the number of additional children in Japan. The data were retrospective birth histories of the 8th Japanese National Fertility Survey carried out by the Institute of Population Problems in 1982. 1st, the authors found that the majority of the Japanese had a balanced sex preference. There was a slight shift from boy preference to girl preference in terms of the parity progression ratio. The effect of the 1st child's sex was small, but the effect of the parity-2 sex combination was as big or bigger than that of other socioeconomic variables. Next, the authors observed some evidence suggesting strong sex preference in opinion and behavior, such as differential intentions of further childbearing due to the sex of previous children and differences in the number of abortions caused by the sex combination of living children. Finally, the authors noted further issues to be examined in the study of sex preference in Japan.

"The major objective of this paper is to demonstrate that interregional income differential is exogenous to interregional net migration, but not conversely. Utilizing Japanese prefectural-based data for 1954-82, we conduct the following three kinds of analyses to confirm this statement. Firstly, a simple comparison of the crests of interregional time-series plots was made to see which occurred first. Secondly, Sims', 1972, test of causality was done to investigate causation between urban/rural income differential and net migration. Finally, per capita income and population share were examined by two-dimensional phase diagram for nine regions." (SUMMARY IN FRE AND GER), (excerpt)

"This paper aims at constructing a certain type of double increment-decrement [life] table which will be suited to analyze intercensal mortality and migration experiences [in Japan]. Use was made of the two successive population censuses at a five-year interval from 1970 to 1975 for Kyoto city." (summary in ENG), (excerpt)

"This paper presents a new method that can be used to reveal the policy objectives with which actual public investment decisions are consistent. Japanese regional investment expenditures from 1958 to 1978 are analyzed, and the dominant policies in effect during this period are identified using this method. A connection between Japanese regional public investment policies and the convergence of population growth across regions is suggested." The suitability of redistributive investment policies as a mechanism for the spatial stabilization of other populations experiencing rapid economic growth is noted., (excerpt)

Based on studies carried out by the author and his associates in areas of Japan and South Asia where malayan and bancroftian filariasis is endemic, this paper recommends methods for use in microfilaria surveys and in the analysis of data obtained in such surveys. The author recommends the use of measured blood samples of 30 mm(3), with which 3 linear smears are made on slides. The blood films are then stained with azure II and eosin. Microfilarial counts made with such smears are, it is claimed, simpler, less expensive, and more reliable than those made with round, thick smears. Furthermore, the use of 3 smears from each person permits the calculation of correction factors, by means of which the detection rates that would be obtained by the use of different volumes of blood may be calculated.Information obtained by the use of this method has proved to be of great use in epidemiological studies of filariasis in endemic areas, in comparing the prevalence of the disease in different populations, and in evaluating the results of control measures. Different ways of recording and classifying the results are described, and the frequency distribution of microfilarial densities is analysed.
