"This article presents estimates of the number of undocumented aliens counted in the 1980 [U.S.] census for each state and the District of Columbia. The estimates, which indicate that 2.06 million undocumented aliens were counted in the 1980 census, are not based on individual records, but are aggregate estimates derived by a residual technique. The census count of aliens (modified somewhat to account for deficiencies in the data) is compared with estimates of the legally resident alien population based on data collected by the Immigration and Naturalization Service in January 1980." Estimates are provided "for each of the states for selected countries of birth and for age, sex, and period of entry categories.... The origins of the undocumented alien population [are described], as well as some of their demographic characteristics. Some of the implications of the numbers and distribution of undocumented aliens are also discussed." This paper was originally presented at the 1984 Annual Meeting of the Population Association of America (see Population Index, Vol. 50, No. 3, Fall 1984, p. 435).  相似文献

Research guidelines are proposed for the study of long-term marriages based on a critical review of existing studies. Current problems in the collection and analysis of the data include the lack of agreement about the minimum length of a long-term relationship, the failure to make couple comparisons, or to follow samples longitudinally. In addition, the response rate is uniformly low and the variables studied are not consistent. Future research should gather data about couples, not just individuals, and should utilize standardized measures. It is important to begin to build a comprehensive and comparable data base of long-term marital relationships.  相似文献

A socioeconomic survey of migrants from Mali, Mauritania, and Senegal who are residing in France is presented. The data are from the official statistics of the four countries concerned and from surveys undertaken in France and the countries of origin. Consideration is given to sources of data, places of origin, economic activity of migrants, length of stay, residence, and illegal immigration.  相似文献

This paper compares the situation of second generation migrants in employing European nations with first generation migrants in the countries of origin. The study focuses on intergenerational changes in employment, unemployment, and further migration. High rates of failure, underachievement, and non-attendance are often found among migrant school children. Girls and boys show high occupational aspirations from age 10-14, but more realistic aspirations by their last year of school. Although vocational training interests many young foreigners, they usually do not get enough training to compete successfully in the labor market. Unemployment affects young foreigners more, and their employment is more unstable, unskilled, and without advancement. Indecision dominates their attitudes about return migration. The country of origin usually cannot provide employment, especially for women, and the longer young migrants have been in employing nations, the less likely they are to want to leave. Difficulty in migrating and the parental desire for superior schooling also limit return migration. On return, migrants 1) experience no continuity of employment or promotion, 2) often find that the skills they have acquired are not valued, 3) must use parallel labor market and cottage industry work to find employment, 4) find that, especially for women and young workers, the unstable employment experienced abroad also affects them on return, 5) find temporary employment or have difficulty in obtaining a job, 6) find both positive and negative views are held by employers concerning them, 7) find that family and connections are the primary means for finding jobs, and 8) discover return migration may not be an end since many second generation migrants will re-migrate for economic and social reasons. School performance, language mastery, social integration and access to training plague migrants and young nationals of similar socioeconomic background. They are unprepared to succeed in the new country and experience conflict of aspirations. First and second generation return migrants experience great frustration, since employment conditions are poor, and may be forced to migrate to a third country.  相似文献

Abstract Extract In their recent paper in this journal M. and Carol Vlassoff are to be commended for helping to remedy the dearth of empirical studies on the old-age security motive for children (and particularly sons) in rural areas of developing countries.(1) However, while the questionnaire which they applied to 357 ever-married men in a rural village in Maharashtra state in India is potentially useful, several of the conclusions they derive from it are unwarranted and, if left unquestioned, would undoubtedly have the effect of setting back the serious investigation of the effects of this motive rather than furthering it. The invalid or at least questionable inferences are taken up one at a time in the order of their appearance:  相似文献

Summary Marital status life tables, which follow a real or synthetic birth cohort through life and the marital statuses of 'never married', 'presently married', 'widowed', and 'divorced', reflect observed marriage, divorce and mortality behaviour and provide a detailed record of a cohort's experience. The present paper analyses such tables for cohorts of men and women born in England and Wales between 1900 and 1945. The results show that the later cohorts deviate substantially from the 'European pattern' of late marriage and high proportions never marrying, and that a dramatic rise in divorce has taken place, so that among the later cohorts one marriage out of four ends in divorce.  相似文献

This Bulletin examines the evidence that the world's fertility has declined in recent years, the factors that appear to have accounted for the decline, and the implications for fertility and population growth rates to the end of the century. On the basis of a compilation of estimates available for all nations of the world, the authors derive estimates which indicate that the world's total fertility rate dropped from 4.6 to 4.1 births per woman between 1968 and 1975, thanks largely to an earlier and more rapid and universal decline in the fertility of less developed countries (LDCs) than had been anticipated. Statistical analysis of available data suggests that the socioeconomic progress made by LDCs in this period was not great enough to account for more than a proportion of the fertility decline and that organized family planning programs were a major contributing factor. The authors' projections, which are compared to similar projections from the World Bank, the United Nations, and the U.S. Bureau of the Census, indicate that, by the year 2000, less than 1/5 of the world's population will be in the "red danger" circle of explosive population growth (2.1% or more annually); most LDCs will be in a phase of fertility decline; and many of them -- along with most now developed countries -- will be at or near replacement level of fertility. The authors warn that "our optimistic prediction is premised upon a big IF -- if (organized) family planning (in LDCs) continues. It remains imperative that all of the developed nations of the world continue their contribution to this program undiminished."  相似文献
