This study, based on Brazilian data from 1976, compared the fertility of migrants and stayers at both origin and destination areas. Observed patterns of fertility differentials were then analyzed in terms of 4 hypotheses of fertility behavior focused on processes of socialization, adaptation, selectivity, and disruption. In the study sample, 31% of migrants moved from rural to urban areas, 45% of moves were between urban areas, and 20% of moves were between rural areas. Among rural-to-urban migrants, only 1/3 moved from traditional to modern regions. To uncover the main patterns of migrant and stayer fertility differentials in the study population, the major flows of migrants by origin and destination were disaggregated by recency of migration, education, and age. The overall conclusions were as follows: 1) rural-urban migration flows need to be disaggregated into various modern/traditional cross-classifications (e.g., modern-rural, traditional-urban, frontier-urban) and greater emphasis needs to be placed on rural-urban, urban-urban, and rural-rural flows; 2) no robust quantitative measures of migrant-stayer fertility differentials held across migrant groups, implying that migrants differing in terms of age, education, origin, and destination are likely to behave in significantly variable fashion with regard to stayer standards of fertility behavior; 3) migrant groups with overall lower fertility levels, such as the young and better educated, are less likely to experience significant fertility reduction to bridge the origin/destination fertility gap; 4) rural-to-rural migrants do not appear to experience any lasting fertility reduction even when they move to areas with lower overall fertility rates; 5) urban-to-rural migrants tend to bridge a larger fraction of the uphill fertility gap than rural-to-urban migrants; and 6) there was evidence of partial adaptation for most migrant categories once disruption effects disappear and evidence consistent with the socialization hypothesis (no fertility reduction for at least 1 generation) was apparent for migrants originating in the least developed parts of Brazil, the frontier region, and the traditional-rural region.  相似文献

Both published results from the 1930, 1947, 1960 and 1971 censuses and unpublished ones are used to examine the influence that religious denomination, socio-economic group and region exerted on the fertility of marriages contracted between 1876 and 1959. A theory formulated by Lesthaeghe and Wilson on the relation between modes of production and secularization and the pace of fertility decline in Western Europe offers — in combination with van Heek's views on the special position of Dutch Roman Catholicism — a starting point for an explanation of why the fertility decline of Roman Catholics, self-employed and agricultural labourers lagged behind.  相似文献

USING DUAL FRAME DESIGNS TO REDUCE NONRESPONSE IN TELEPHONE SURVEYS   总被引:1,自引:0,他引:1  
This article reports on the results of a series of experimentsdesigned to improve response rates for telephone surveys. Inthree surveys telephone households were selected using bothstandard random digit dialing (RDD) techniques and lists oftelephone numbers purchased from a commercial firm. In the RDDportions of the samples "cold contact" interviewing methodswere used; in the list frame portions advance letters were mailed,and the listed household name was used in the introduction.Experiments were designed to test the effects on response ratesof the advance letters and use of the listed household nameas a means of establishing rapport. The advance letters increasedresponse rates, but no difference could be attributed to theuse of names. The mixture of RDD and list sampling techniquesis also used to evaluate the effects of relative response rateson substantive findings. The cost consequences of these dualframe designs are assessed along a number of dimensions, andthe cost and error components of these designs are discussed.  相似文献

The occupational distributions of the native-born and foreign-born in the Australian labor market differ greatly. The disparity between the occupational distributions is greatest among the middle age-bracket, and among immigrants from Eastern Europe and the Mediterranean region. Analysis of occupational attainment using unit record data from the 1981 Census shows that as duration of residence in Australia lengthens, the occupational distribution of the overseas-born converges toward that of the Australian-born. Moreover, birthplace groups differ in the degree of upward mobility associated with length of residence in Australia: immigrants from non-English-speaking countries tend to make greater occupational advances than their counterpart from English-speaking countries. This suggests a higher degree of international transferability of human capital skills among immigrants from English-speaking countries. The analysis also highlights the concentration of immigrants from non-English speaking countries in low-ranked occupations, and the relatively minor influence of education on the occupational attainment of immigrants from these birth place regions.  相似文献

A survey of corporate Planning in Britain suggests that the way the process is organized varies with the need of the firm. There appear to be two types of needs which foster the development of the planning activity—strategy development and co-ordination. In capital intensive companies, threatened by technological or market change, there is a need for reappraisal of the firm's overall strategy. On the other hand, in a large diversified firm the requirement may be to co-ordinate the plans of different divisions and departments, particularly investment proposals. This article suggests a framework for the analysis of these planning needs.  相似文献
