Estimating Changes of Residence for Cross National Comparison

First, among the various spatial models used, the model linking migrations to the zoning of the territory provides a simple summary of this relationship, but its parameters do not have a clear plain language meaning for international comparison. Second, the “migrant-migration” model derives an instantaneous rate based on migrant numbers measured over variable durations that is independent of multiple and return moves occurring over a longer interval. International comparison is thus only possible for the instantaneous mobility rate (change of residence), a standard indicator whose meaning is clear. The authors use numerous examples to show that the simultaneous use of both types of
models provides a means, under certain conditions, to approximate such a rate, that can be linked to the parameters of these models. The validity of these models can be tested and confirmed using data from countries where direct measures of changes of residence are available.

The high variability in the levels of fertility, mortality and migration among Indonesian provinces provides a rich opportunity to perform a statistical analysis on the possible relationship between these demographic components. The analysis utilizes data from the 1980 and 1990 Indonesia population censuses, and the 1995 intercensal population survey with province as the unit of analysis.

Classification and measurement of such phenomena is inevitably complex. Nevertheless, given the significance of mobility, it is surprising that such little progress has been made in codification. In other fields of demography, such as fertility and mortality, common standards for data collection and computation of key measures have been developed -for example, the international classification of diseases was developed to ensure comparability in the collection of deaths data and there are universally agreed measures for analysis and reporting.

The family as a social unit has a major contribution in making decisions related to migration, especially in developing countries (Root and De-Jong, 1991). Data from the 1995 Indonesian intercensal survey clearly documents this phenomenon by showing that more than 50% of internal migrants have cited marriage and family reunion, as well as economic, education, housing concerns as the primary triggers for migration. In addition, the survey provides information on family circumstances (such as family structure, family sources, and previous mobility experiences among family members) that allows for an analysis of migratory trends at the familial level. Adopting a model of family migration as developed by Root and De-Jong (1991), this paper aims to contribute to the study of family migration in Indonesia by exploring trends in family migration as documented in the intercensal survey data. However, the data only allows for the measurement of migrated households rather than family migration. Here, a migrated household is defined as a household in which at least one member is a migrant. A logistic regression model is utilised to explain the differentials in household migration by selected explanatory variables.

This paper focuses on the use of an indirect internal migration estimation method applied to Mexican and Indonesian census data. It shows that the mobility propensities of infants can be used to infer the corresponding propensities of all other age groups. However, the promise of this method is reduced in instances of inadequate data, and great care must be taken to identify outlying values in the data and to correct obviously erroneous patterns. Future work increasingly will be directed to this issue.

We exploit detailed life history calendar data to conduct a more refi ned and defi nitive analysis of the relationship among personal traits, urban residence, and fertility. Although urbanization is generally associated with lower fertility in developing countries, inferences in most studies have been hampered by a lack of information about the timing of residence in relationship to childbearing. We fi nd that the effect of urbanization itself is strong, evident, and complex, and persists after we control for the effects of age, cohort, union status, and education. Our discrete-time event-history analysis shows that urban women exhibit fertility rates that are, on average, 11% lower than those of rural women, but the effects vary by parity. Differences in urban population traits would augment the effects of urban adaptation itself. Extensions of the analysis point to the operation of a selection effect in rural-to-urban mobility but provide limited evidence for disruption effects. The possibility of further selection of urbanward migrants on unmeasured traits remains. The analysis also demonstrates the utility of an annual life history calendar for collecting such data in the fi eld.

Differences in data collection, in geography and in measurement intervals seriously hinder rigorous cross-national comparisons. We supplement data from the University of Minnesota IPUMS collection to make comparisons between 28 countries using both five year and lifetime measures of migration, and focusing particularly on migration intensity and spatial impacts. We demonstrate that Courgeau's k (Courgeau 1973) provides a powerful mechanism to transcend differences in statistical geography. Our results reveal widespread differences in the intensity of migration, and in the ages at which it occurs, with Asia generally displaying low mobility and sharp, early peaks, whereas Latin America and the Developed Countries show higher mobility and flatter age profiles usually peaking at older ages. High mobility is commonly offset by corresponding counter-flows but redistribution through internal migration is substantial in some countries, especially when computed as a lifetime measure. Time series comparisons show five year migration intensities falling in most countries (China being a notable exception), although lifetime data show more widespread rises due to age structure effects. Globally, we estimate that 740 million people, one in eight, were living within their home country but outside their region of birth, substantially above the commonly cited figure of 200 million international migrants.
