The paper introduces, for age-distribution population vectors, a class of distances to the stable equivalent; each of these distances converges monotonically to zero as the population approaches stability. The Kullback distance, considered earlier to be unique as a measure with this property, turns out to be a mere specimen of this class. It is shown that the very feature of monotonic convergen...

This article describes a methodology for applying a discrete-time survival model-the complementary log-log model-to estimate effects of socioeconomic variables on (1) the total fertility rate and its components and (2) trends in the total fertility rate and its components. For the methodology to be applicable, the total fertility rate (TFR) must be calculated from parity progression ratios (PPR...

The idea that trade-offs between offspring quantity and quality shape reproductive behaviour has long been central to economic perspectives on fertility. It also has a parallel and richer theoretical foundation in evolutionary ecology. We review the application of the quantity-quality trade-off concept to human reproduction, emphasizing distinctions between clutch size and lifetime fertility, a...

CONTEXT The persistent low contraceptive use and high fertility in Nigeria despite improvements in educational achievements calls for an examination of the role of factors, which may moderate the use of modern contraception. This article explores the influence of sexual autonomy on the use of modern contraceptive methods among women and its relative importance compared with other, more traditio...

BACKGROUND Hydatidosis, as the most important zoonotic parasitic disease in Iran, has posed many health and economic losses. This study was conducted to investigate the demographic characteristics of hydatid cyst surgeries in hospitals of East Azerbaijan Province, Northwest of Iran. METHODS Demographic characteristics of all patients with hydatid cyst surgery in hospitals of the province, dur...

Résumé Abstract Fertility remains higher and contraceptive levels are substantially lower in Sub-Saharan Africa than elsewhere in the developing world. In this paper we use information on individuals and couples provided in recent Demographic and Health Surveys (DHS, fifth wave) undertaken in Ghana, Kenya, Madagascar, and Zambia. We use bivariate and multivariate techniques to examine the deter...

OBJECTIVE To assess whether the strategy of "a midwife in every village" in Indonesia achieved its aim of increasing professional delivery care for the poorest women. METHODS Using pooled Demographic and Health Surveys (DHS) data from 1986-2002, we examined trends in the percentage of births attended by a health professional and deliveries via caesarean section. We tested for effects of the e...

Reproductive health surveys often face difficulties in measuring age and durations. Heaping is the phenomenon that certain dates, ages or durations are overor underrepresented. Following the calendar method used in several Demographic and Health Surveys, the current research proposes the use of a local timepath calendar, based on time perceptions of women in South India. The objective of the ca...
