Determinants of migration values and expectations in rural Thailand.

"Based on the argument that values and expectations underlie behavioral motives, this study explores the determinants of migration-related values and expectations, and whether they are intervening factors in explaining intentions to move among residents of rural northeast Thailand. Data from the 1992 National Migration Survey of Thailand identify four migration-related value-expectancy dimensions: income, affiliation, stimulation, and comfort. Logistic regression analysis shows that landownership and being married are associated with higher expectations, while a diversified village economy, a village economy development program, and a younger and extended household structure are associated with lower expectations of attaining valued goals in the local rural village. The analysis also shows that value-expectancy concepts are only partial intervening explanations for intentions to move or stay."

Gender, values, and intentions to move in rural Thailand.

"This article explores gender differences in the intentions to move among a sample of young adults in rural northeastern Thailand. Based on the value-expectancy framework of migration decisionmaking, an explanatory model is tested which includes migration-related value measures along with individual, household and community-level determinants of both intentions to move and change in intentions to move. Multinomial logistic regression results based on data from the 1992 Thailand National Migration Survey provide some support for the hypothesis of gender-specific determinants of both intentions to move and the reconsideration of migration intentions. For men, value measures of affiliation and comfort, social networks, the presence of young children in the family, and land holdings are significant determinants of migration decisionmaking; for women income and comfort values, the presence of elderly persons in the household, community size, and crop losses are the salient factors."

Motive and the geographic mobility of very old Americans.

The proposition that motives for migration are important in explaining geographic mobility of very old persons was explored in this study. Data from the biennial 1984 through 1990 rounds of the Longitudinal Study on Aging were used to predict the move/not-move behavior of a nationally representative sample of noninstitutionalized respondents aged 70 years and over in 1984. Six motives for elderly migration were identified: health, affiliation, economic security, comfort, functional independence, and getting on with life after family crisis. When incorporated within this motivational framework, reason-for-move data showed that health was not the dominant motive; responses were divided among the five other motive categories. The logistic regression analysis showed that increasing disability was positively related to mobility for respondents in only one of six motive categories. The results suggest that a motive-for-migration perspective broadens the debate on types of, and explanations for, migration behavior of noninstitutionalized very old Americans.

Changing occupational characteristics of U.S. immigrants.

"The purpose of this research is to: (1) describe changes in the occupational characteristics of immigrants to the United States between 1972 and 1986; (2) analyze immigration statistics to see how policy admission categories, source country, and individual demographic factors help determine the entry patterns of professional and technical immigrant workers in 1972 and 1986; and (3) evaluate the immigrant stream recomposition argument that the changing levels of professional and technical occupational immigration [are] due to shifts in class and visa categories, region of origin, and demographic characteristics of workers admitted to the United States. In the conclusions we discuss how changes in immigration policies during this period may have contributed to the statistical patterns on occupational skills of immigrants."

International and internal migration decision making: a value-expectancy based analytical framework of intentions to move from a rural Philippine province.

"The study compares determinants of internal and international migration intentions, drawing upon interview data from a sample of adults in Ilocos Norte, a largely rural province in the Philippines. A regression model is applied to test the relative determinants of intentions to migrate to Manila and to Hawaii. The study is based on a value-expectancy model of migration decision making. The results document the importance of subjective expectations related to the attainment of different values and goals in Manila and Hawaii."

Aged in cities: residential segregation in 10 USA central cities.

This study focuses on the segregation of the aged in ten USA cities. The objectives are to determine the degree of segregation of elderly within cities, and how the pattern varied from 1960 to 1970 by size of city, age of city, and for cities that are growing and declining in population. Census data were used to compare proportions of the population 65 and over living in central city and suburban locations, and a summary Index of Dissimilarity was computed to measure the degree of age segregation by census tracts. In all metropolitan areas there was a disproportionate share of the elderly residing within the central city and considerable segregation in certain census tracts within the city. However, the degree of segregation showed no pattern of increase between 1960 and 1970. There was less segregation of the aged in older, declining cities and greater segregation in younger, growing cities. These findings suggest that age segregation is in part a function of the urbanization process.

Residential preferences and migration.

For some time now, public opinion polls have revealed Americans' strong preference to live in comparatively small cities, towns, and rural areas rather than in large cities. However, as Fuguitt and Zuiches (1975) have reported, the majority of people also want these places to be within commuting distance of a large metropolitan city. This research tests the hypothesis that size-of-place and urban proximity preferences are factors in the dispersal of population through migration. A one-year panel survey of Pennsylvania households indicates that only about one household in ten that moved actually attained its preference for a smaller-sized place or a location more distant from a large city. Preferences for smaller-sized places and proximity to a city were not correlated with where people actually moved when the size and proximity of the previous residence were taken into consideration.
