Monitoring the education gap in Thailand: trends and differentials in lower and upper secondary schooling.

"Using 1980 census and 1987 survey data on birth cohorts to examine recent primary and secondary school enrollment trends [in Thailand], this study reports that primary enrollment is nearly universal but secondary enrollment is much less prevalent. The study assesses several factors thought to influence enrollment and finds that urban residence, parents' completion of primary school, the mother's positive attitude toward education, and the family's being comfortable economically to be associated with children's enrollment in secondary school. It also indicates that, for moderately well-off families, proximity to schools has a major influence on secondary school attendance. For the wealthiest families, however, distance is not a hindrance to attendance, and for the poorest families, having a school nearby is not sufficient to ensure attendance."

Has Thailand's fertility decline stalled?

Thailand is 1 of the third world countries in which a very substantial fertility decline has occurred during the last 2 decades. However, there has been some recent concern, based on fertility rates derived from 3 national contraceptive prevalence surveys conducted in 1978/1979, 1981, and 1984, that the fertility decline may have lost momentum at a level well above replacement fertility. New evidence now available from a more recent national survey which permits calculation of retrospective fertility trends, in combination with those from registration data, clearly contradicts the suggestion of a fall in the fertility decline. Moreover, because expected family size remains low among women currently starting their reproductive careers and evidence shows that the preferred number of children has fallen more or less steadily, low fertility may be expected to be a feature of the Thai population for some time to come.

Starting, stopping, and spacing during the early stages of fertility transition: the experience of German village populations in the 18th and 19th centuries.

Examination of the reproductive histories of a sample of German married couples during the 18th and 19th centuries provides insights into behavioral changes involved in the shift from natural fertility to deliberate marital fertility control. A simple accounting scheme is used to assess the relative contributions of starting, spacing, and stopping to changes in family size during the initial phases of the fertility transition. The results suggest that in rural Germany, attempts to terminate childbearing prior to the end of the reproductive span were far more important in initiating the onset of fertility transition than efforts to deliberately prolong intervals between births or changes in the timing of the start of childbearing.

Effects of birth rank, maternal age, birth interval, and sibship size on infant and child mortality: evidence from 18th and 19th century reproductive histories.

There has been long-standing interest in the effects of maternal age, birth rank, and birth spacing on infant and child mortality. Contradictory inferences about the role of these factors have arisen on occasion because of the absence of adequate controls, the use of cross-sectional or incomplete reproductive histories, and inattention to the effect of family size goals and birth limitation practices. This study analyzes completed reproductive histories for German village populations in the 18th and 19th centuries, a period when deliberate fertility control was largely absent. Our results confirm previous studies of the association of infant mortality with maternal age, although in the present data these differentials are largely limited to neonatal mortality. They also confirm the importance of birth interval as a factor in infant mortality. Sibship size is positively related to infant mortality even when birth rank is controlled. However, once sibship size is controlled, there are no systematic differences in infant and child mortality by birth order. The mechanisms relating sibship size and mortality are explored.

From natural fertility to family limitation: the onset of fertility transition in a sample of German villages.

Utilizing data from a sample of German village genealogies, it is possible to document the changes in reproductive patterns on the family level that started to take place in Germany during the nineteenth century and formed the basis for the secular decline in fertility which eventually encompassed the entire country. One striking finding from this study was the substantial diversity among the small sample of villages in terms of the timing of the emergence of family limitation. While couples in all villages who married during the last half of the eighteenth century appeared to be characterized predominantly by natural fertility the emergence of family limitation began as early as the turn of the nineteenth century in some places and as late as the end of the nineteenth century in others. Occupational differentials with respect to family limitation were also examined. There is little evidence that changes in birth spacing played an important part in the initial phase of the fertility trnsition. Rather, the underlying process appears to involve a change from fertility patterns that were characterized by the absence of parity-dependent control to one in which attempts to terminate childbearing in response to the number of children already born becomes widespread.

Breast-feeding and population growth.

Abandonment of breast-feeding in parts of the world where contraception is not in common use may mean both higher birthrates and, especially among the poor, higher infant death rates. In this article estimates of the magnitude of these effects are made.
