    The aim of this paper is to study the status of the elderly, particularly with relation to their health situation and related factors. Multivariate regression analyses are carried out on (i) the current health status of the elderly, (ii) attitude and behaviour of family members towards elderly relatives, and (iii) the status of the elderly within the family as assets or liabilities, in order to study the relationships among several socio-economic, demographic and cultural factors. The above-mentioned study variables are taken as dependent variables and explained separately as they indicate different characteristics of the elderly and have varying impacts on the society. Interrelationships among these study variables have also been discussed. Explanatory (independent) factors are examined on both household and individual (elderly) levels. Factors such as satisfaction with the achievements of one's son(s), social and economic status of the household, the age of the elderly person, monthly income of the elderly person, and maximum education level of the household have been found to be important variables contributing significantly towards the welfare of the elderly in rural northern India. The study is based on random sample data of 980 elderly people collected from the rural areas of the three largest northern states in India.

    This paper examines whether parent-youth coresidence and parents' income affect the labor supply of unmarried Japanese women. The Japanese Panel Survey of Consumption is used to estimate the labor supply function. Parent-youth coresidence reduces the labor supply of unmarried women. However, the reason differs with generation. Unmarried women whose parent is under 60 years old and who live with their parents reduce the labor supply because their parents support them, while those whose parent is more than 60 years old reduce the labor supply because they have to help a widowed father. Moreover, parents' income does not affect the labor supply. Specifically, unmarried women cannot use their parents' income as unearned income. In conclusion,unmarried women enjoy their life with their altruistic parents when they are young. However, as they get older, they have to help their prents.

    For the better observation of fertility trend, it is necessary to analyze Total Fertility Rate(TFR) in tempo and quantum aspect. The former indicates the changes in childbearing timing and the latter shows the changes in the number of children of a woman in her life. There exist different methods to decompose TFR in tempo and quantum factors and among them, so called Ryder Index posed by N. Ryder in his pioneer works is the most popular. However, one needs all the Cohort Total Fertility Rates(CTFRs) in reference to the age-specific fertility rates from 15 years to 44 years to calculate the Ryder Index in a one year period. Thus, due to the limitation of available data, the tempo index(TI) and the quantum index(QI) could be obtained mostly in only limited periods of time. To solve this problem, the author developed the new brief method(named Simple Method) to use only TFRs and CTFRs time series data without detailed age-specific fertility rates. In this paper, we introduced this Simple Method in methodological detail compared with Ryder's Method and explained mathematically the possibility to obtain almost same values with Ryder Index. Then, using time-series and periodical age-specific fertility rates in Switzerland 1932-1996 and in Germany(former West and East Germany), Austria, Switzerland, the Netherlands and Japan after World War II, we calculated the tempo and the quantum by both methods and attested the results. Trends of TI and QI were identical and the RMSPE : the root mean square percentage error(RMSPE) were usually 1%-2% and 5%-6% at most.

    The Russian population shrank by 1.8 million people between the 1989 and 2002 censuses due to natural decreases, caused mainly by an increase in early deaths of males and a decline in birth rates. The life expectancy of males decreased to 57.6 years in 1994, the year of the bottom of demographic deterioration. In particular, mortality rates of 30-44-year-old men almost doubled from 1989 to 2002. If we compare these data with corresponding Japanese ones in 2002, the mortality rates of 25-44-year-old Russian males exceed those of Japanese by more than 8 times. This paper analyses the causes and regional characteristics of this unprecedented deterioration in male longevity, using the official data of mortality by age and region in those 14 years from 1989 through 2002 that have been unavailable until recently. Note that "regions" here refers to the 89 "subjects of federation," including republics, krais, oblasts and so on. In the first place, in the principal analysis of annual mortality data by region we confirmed that regional differences in the mortality of both all men and the male working age population (16-59 years old) remained almost unchanged in these 14 years. Male mortality continued to be high in regions of the central and north-west parts of European Russia, excluding Moscow and St. Petersburg (where an influx of younger men from both inside and outside of the country may have reduced mortality rates), as well as in some regions of east Siberia, while in regions of the north Caucasus mortality remained low. The data for male mortality rates by age in 2002 indicated that the mortality rate of the younger generation (25-34 years old) was high in Siberia, the while mortality rate of the older cohort (35-44 years old) was high in the central and north-west parts of European Russia. In the next step, we carried out principal and cluster analyses on the regional data for male mortality of the working age population and the causes of their deaths. The result of these analyses showed that regions of the central part of European Russia, excluding Moscow, were characterized by a high mortality rate of the working age population and high percentage of deaths caused by diseases of the circulatory system and cancer, while regions of east Siberia and Kalinigrad were characterized by high mortality rate and the prevalence of deaths caused by trauma and poisoning, including suicide and homicide. Note that the diseases of the circulatory system contributed most to the increase in male deaths from 1989 to 1994, followed by trauma and poisoning in Russia. Finally, similar analyses were carried out on the regional data for male mortality by age (25-29, 30-34, 35-39 and 40-44 years old) and causes of death for the male working age population. The results clearly showed that in regions of the central and north-west parts of European Russia (excluding again Moscow and St. Petersburg), where the mortality of 40-44-year-old men was high, deaths caused by diseases of the circulatory system were dominant, while in east Siberian regions and Kaliningrad, where the mortality of 25-34-year-old men was high, deaths caused by trauma and poisoning, including suicide and homicide, prevailed. Statistics of crimes by region also indicated that among crime rates in Russia; those for Siberia were relatively high. The earlier literature pointed out three main causes of the increase in early deaths of Russian males: 1) economic and social crisis caused by system transformation which started in early 1990s; 2) the influence of the anti-alcohol campaign launched by Gorbachev in mid-1980s and its artifact; and 3) the influence of longer trends of male mortality increase which started in the 1960s. This paper suggests that both system transformation and increases in alcohol consumption following the liberalization of alcohol prices and sales in 1992 had a significant influence on the male

    The purpose of this paper is to elucidate possible reasons for the difference in the number of foreign residents in Japan in 2000, with respect to the two major population statistics: the population census and statistics on registered foreigners. Based on an examination of the ratios calculated from the numbers common to the two statistics, and interviews with the organizations concerned, the following findings have been obtained. Regarding the situation that the number from the statistics on registered foreigners is higher than that from the census, the following four specific reasons are conjectured. First, the times at the two sets of statistics differ by three months. Second, foreigners holding "temporary visitor" residence status are included in the registration statistics only. Third, registered foreigners may have left Japan with a re-entry permit at the time of the census. Fourth, a certain number of the registered foreign residents did not cooperate with the census due to their illegal hope to work. As for the situation that the number of residents in the census exceeds that of the registered foreigners, it is recognized that civilian foreigners with US nationality who work within the United States' military bases in Japan tend to consider it unnecessary to follow the registration procedure. Among the five reasons mentioned above, the attitude of non-cooperation with the census is conjectured to be the most important. In terms of nationality, Philippine citizens exhibit the greatest difference between the two statistics. Thus, the conclusion is that the number of foreign residents in Japan shown in the census reports tends to be under-representative; the number in the registered foreigner statistics is more reliable.
