Age patterns of chinese marital fertility, 1950–1981

Coale and Trussell’s model of marital fertility is used to analyze data from China’s National One-per-Thousand Fertility Survey. Rural China experienced a regime of natural fertility until 1970, after which levels of fertility control rose with unprecedented speed and with an age pattern starkly dissimilar from that observed in other populations. Urban marital fertility was apparently under a modest level of deliberate control in the 1950s, with a sustained rise in control beginning in 1963. Natural fertility was low relative to other populations, with the urban level exceeding the rural.     

The changing impact of white migration on the population compositions of origin and destination metropolitan areas

Increased migration to the sunbelt and the metropolitan-nonmetropolitan "turnaround" represent departures from long-standing redistribution trends. Although these patterns have been examined from a number of perspectives, their consequences for individual metropolitan areas have not yet been brought to light. In the present study, stream-disaggregated data for the late 1950s and late 1960s are employed to assess the impact of recent migration on the sizes and compositions of white populations in thirty-one large metropolitan areas. Most large northern SMSAs have been experiencing the "new" migration patterns since the late 1950s. They have incurred net out-movements of whites to both metropolitan and nonmetropolitan areas. In their exchanges with nonmetropolitan areas, however, they have managed to retain greater numbers of college graduates and professional workers. Southern and western SMSAs did not sustain losses to nonmetropolitan areas during either period. They did appear to gain both total and high status population as a result of interregional metropolitan redistribution.     

Immigration and internal migration “flight”: A California case study

Recent analyses of 1990 census migration data have pointed up disparities in the way immigration and internal migration contributions affect an area's demographic profile. They show that there is little overlap between states with large population gains from internal migration from other parts of the United States and states with large population gains from immigration from abroad. This emerging pattern, along with the fact that immigration and internal migration select on very different demographic characteristics, could lead toward a demographic balkanization of the nation's population. This paper evaluates immigration-induced out-movement from California, based on an analysis of recently released migration data from the 1990 U.S. census. The results presented here suggest that California's out-migration consists of two different migration systems: first, an immigration-induced flight that exports lower income and less-educated Californians, primarily, to the nearby states of Washington, Oregon, Nevada and Arizona. And second, a more conventional migration exchange with the rest of the United States that involves the redistribution of better educated, higher income migrants. It is the former migration system which appears to be most responsive to the low-skilled immigration flows, while the latter should be responsive to more conventional labor market employment characteristics. This implies that, irrespective of changing economic conditions in the state, the continued immigration of low-skilled migrants will lead to more losses of native-born internal migrants to neighboring states and metropolitan areas. However, these migrant streams will not be made up of the best and brightest residents that characterize most conventional migration streams.A longer version of this report with more extensive background statistics isResearch Report 94–306 (Frey, 1994b) available from Publications, Population Studies Center, The University of Michigan, Ann Arbor, MI 48104.     

The effects of food and density of the movement ofArion ater andAriolimax columbianus (Pulmonata: Stylommatophora) between habitats

Summary Experiments were conducted to determine if slug density, or food quantity and quality could cause dispersal by slugs.Arion ater dispersed quickly from overcrowded areas, where high mortality was incurred by this species. Poor food conditions, caused more dispersal than good food conditions, but food had no effect on the mortality ofA. ater. Neither food nor density factors had significant effects on the dispersal ofAriolimax columbianus. However, moreA. columbianus died in the high- than low-density treatments.A. columbianus mortality was unaffected by the food factor. DispersingArion were heavier than non-dispersers, but there was no difference between the weights of dispersing and non-dispersingAriolimax. There were significant seasonal changes in the dispersal rate, mortality and weight of dispersingArion, whereas only the mortality ofAriolimax changed significantly during the experiments. SinceArion ater did not markedly reduce its activity during unsuitable weather it was able to leave areas of poor food and high slug density fairly rapidly.Ariolimax columbianus' large size allowed it to remain inactive during unfavourable weather and permitted this species to be relatively unresponsive to the experimental treatments.     

Sons,Daughters or Both?: An Analysis of Family Sex Composition Preferences in the Philippines

An analysis of family sex composition preferences as well as the relationship between actual family sex composition and desire for no additional children among a national sample of Filipino women is presented. An emphasis on balance or son-daughter equivalence is strongest in Metropolitan Manila. Son preference is highest in rural Mindanao and Sulu, primarily due to the concentration of Muslims in this section of the country and secondarily to its pioneer environment and the presumed utility of sons in such a milieu. The importance of eliciting sex composition preferences from both husbands and wives as well as distinguishing the “striking for a balance” from sex-linked preferences in future research is discussed.     

Educational efforts in the implementation of rural family planning programs in East Pakistan

The pilot family planning studies reported in this paper were conducted in a rural area adjacent to the city of Dacca in East Pakistan. It reports the preliminary findings of action-research in the implementation of educational efforts to reach rural villagers of a developing country.Preliminary analyses of the records identify two significant educational problems: (1) most of the villagers (85-90 percent of the couples) who initially accepted contraceptives do not truly adopt and become continuing users and (2) the continuing users (10-15 percent of the initial users) are generally characterized by large families. (Later data show an even lower percentage of continuing users.)The field activities in the development of various educational approaches to family planning are described. Three separate geographic areas (from 15,000 to 20,000 population) were each approached in a different way, varying in the number and educational qualifications of the workers and in the degree of involvement of village leadership. Preliminary analyses of field records indicate that these variations of approach apparently have little effect on the percentage of the population willing to accept contraceptive supplies.It is the opinion of the writers that more intensive educational efforts are necessary at the village level to develop social support for continuing use of contraception and to gain adoption of contraception by younger married couples primarily for spacing of births.The impact of introduction of the IUCD in populations where condoms and foam tablets have been available for one to two years has also been reported. Preliminary findings indicate that the IUCD encourages adoption by previous non-users and may increase the over-all percentage of contraceptive users.     

Community size preference status,community satisfaction and migration intentions

Increasing attention has been directed to the effect of cognitive factors on migration decision making. We evaluate the influence of community size preference status and six domains of community satisfaction on migration intentions per se and short- vs. longterm migration intentions, separately, simultaneously, and with controls on community involvement and social position. The data are from a 1988 statewide migration survey of 851 Utahns. Separate multivariate analyses are conducted for metropolitan and nonmetropolitan residents. Satisfaction/dissatisfaction with selected features of community life primarily impacts migration intentions per se while community size preference status dominates the time frame of migration intentions.     

Women and retirement planning: towards the "feminization of poverty" in an aging Hong Kong

Hong Kong's population is aging but retirement research is largely missing from the research agenda in Hong Kong. This study, based on a telephone survey of 1,078 respondents, examines middle-aged adult's retirement planning activities in Hong Kong. The findings show men are more likely to be involved in financial planning, while women are more likely to take part in some forms of health, living arrangement and psychological planning for retirement. Further, there are age, education and income differences in the various forms of retirement planning activities within genders. Women are living longer; because of their lack of financial retirement planning, they are prime candidates for poverty. The discussion concludes with policy implications related to assisting midlife individuals, in particular women, in planning for retirement.
