N. Methods of Research and Analysis Including Models

Studies concerned with demographic methods and with methods from other disciplines that have been applied to demographic data as a whole. Includes mathematical demography and studies on methods of estimation and indirect estimation. Methodological studies and models concerned with one demographic variable, such as migration, are coded under the category concerned with that topic and cross-referenced to this heading. Studies on models used to investigate relationships between demographic variables and for the analysis of empirical data are also coded under this heading.

The authors propose an alternative to the treatment of event histories as continuous processes. "Specifically, they show that virtually identical estimates can be obtained from logit regressions and hazard regressions, provided that each month in the history provides one observation in the logit framework." They describe a discrete-time regression model and apply it to data from Sweden concerning third births.

The author describes the concepts involved in the analysis of demographic events in the context of the family life cycle. Specifically, he notes that the various stages in the family life cycle do not occur independently of changes in the social and professional lives of the individuals concerned or of changes in the spatial dimension in which the stages develop. The main part of the study is devoted to consideration of how the data needed for such event history analysis can be obtained, particularly from retrospective surveys.

The authors consider methods for analyzing event histories when such histories are both left- and right-censored. They first discuss the advantages and disadvantages of current-status data, and then review the fitting of proportional hazards and accelerated life models to such data. An example is provided concerning age at menarche in northeastern England in 1967.

"In this paper a method is [proposed] for the simultaneous estimation of reciprocal effects between interdependent processes of the human life course as recorded in event history surveys. The method is first illustrated for the case of just two processes running parallel to each other on the basis of a small set of randomly generated data, and then applied to empirical duration data for four processes from a Dutch event history survey conducted in 1984: cohabitation, marriage, conjugal union dissolution and fertility....Results obtained for the experimental data set suggest that partial estimation may be particularly misleading in the case of processes which appear to play a subordinate role within an interdependent system."

The author proposes the collection and use of biographical data for the analysis of household structure, migration, and career choice. "The analysis...renders it possible to approach human behaviour patterns more accurately and can detect different kinds of dependence between phenomena. In the line of longitudinal analysis, the analysis of life event history data provides a new tool which offers promising possibilities for future research." The geographical scope is worldwide.

Methods of measuring child mortality in developing countries using data on preceding births are examined. The study was prepared as a doctoral dissertation at Princeton University.

The general tools available to the demographer for handling incomplete data are first reviewed. The author then discusses the methods for analyzing event history data when such data are complete, and proceeds to suggest modifications to these methods when incomplete information is available on the times of events or when covariates are missing.

In: Demographic applications of event history analysis, edited by James Trussell, Richard Hankinson, and Judith Tilton. 1992. 9-37 pp. Clarendon Press: Oxford, England. In Eng.
The authors "discuss the analytic issues that arise in identifying, controlling, and--under certain circumstances--estimating the effects of unobserved variables in demographic analyses of a wide variety of time-to-occurrence data. [They] argue that the treatment of the effects of unobservable variables in demographic modelling is a direct and natural extension of the evaluation of model specification for analyses where all relevant variables are assumed to be observed."

58:40763 Mitra, S. A birth model with oscillating rate of growth. Janasamkhya, Vol. 8, No. 1, Jun 1990. 35-40 pp. Kerala, India. In Eng.
"Integral equations similar to those generated by the assumption of unchanging vital rates in a closed population leading to eventual stability can be obtained by allowing the rates to vary according to some prescribed rules. In spite of these changing patterns of the vital rates, some of these models have earlier been found to approach stability where the solutions of the stable parameters can be obtained by following the usual straightforward methods. In this paper, a similar integral equation with changing vital rates has been presented which can also be solved in a similar manner. However, the resulting rate of growth does not stabilize but continues to oscillate. The period and amplitude of this oscillating rate of growth together with its central value can be determined from the specified pattern of variation of the vital rates."

"This paper first introduces the LASA-DO [Look And See And-Do] bridge as a metaphor to better understand solutions for linking data producers to data users. The bridge that links producers and users is known as 'LASA-DO'. How this bridge was constructed in Nigeria to link the Nigerian Demographic Health Survey (NDHS) to potential users is presented in some detail...."

"This paper addresses theoretical and practical issues of combining qualitative and quantitative methods in observational research design, with particular emphasis on the complementary use of focus groups and sample surveys....The article focuses on the concurrent use of these two methods, using a study of the socioeconomic consequences of family size in rural Thailand conducted in 1988 to illustrate the central themes and provide specific examples."

The author analyzes Brentano's economic theory of the family, originally published in 1909, and contrasts it with that of G. S. Becker. A model relating Brentano's concept of the supply of goods to fertility decline is then outlined.
