The main aim of this study was to examine factors affecting the demand for a third child (DTC). Methods: This cross-sectional study wa...
Human survival probability and fertility decline strongly with age. These life history traits have been shaped by evolution. However, research has failed to uncover a consistent genetic determination of variation in survival and fertility. As an explanation, such genetic determinants have been selected in adverse environments, in which humans have lived during most of their history, but are alm...
BACKGROUND Fertility is high in rural Ethiopia. Women in the reproductive age group differed in various characteristics including access to food and encounter to drought which requisite the assessment of determinants of fertility. METHODS Reproductive age women were recruited from a DSS, the Butajira DSS database. A DHS maternity history questionnaire was administered on 9996 participants. Da...
BACKGROUND Patient-centered reproductive medicine (PCRM) is important for quality of care, and this is increasingly being recognized. However, its scientific basis is unclear. The main research questions addressed in this review are: 'How has the patients' perspective on fertility care been examined (method and quality)?' and 'What is the perspective of patients in developed countries on fertil...
Abstract This research explores fertility correlates in the Petén, a high fertility region of Guatemala, during the 1998-99 time period. By taking into account land use and labor characteristics at the household and community levels in addition to individual level factors related to diffusion, gender equity, and socio-demographics the research aims to enhance and update the traditional applicat...
The dramatic decline in mortality rates during the nineteenth century put the countries of the world into an imbalanced stage of demographic transition. Developed societies adopted fertility control methods and achieved a balance in their annual rate of population growth, whilst developing countries and traditional societies are still confronted with the following serious hazards: 1. Poor healt...
Fertility has declined very markedly in the majority of developing countries over the past thirty to forty years, and it continues to decline almost everywhere. As a result, fertility has reached very low levels in many countries. In addition, currently more than 40 per cent of the world’s population lives in countries with total fertility levels lower than 2.1 children per woman, the level tha...
Fertility is the major determinant of population growth rate. In the early 1960’s Pakistan was the pioneer country which focused on the family planning issues to control the fertility rate so that population growth would be controlled. But it has been observed that the population growth could not be controlled at the desired level yet. The main objective of this study is to explore the factors ...
We hypothesize that the perceived returns to human capital and to income uncertainty are important determinants of recent cross-sectional variation in Latin American fertility. An empirical study of cross-country individual level data supports the hypothesis. In particular, we find that a higher perceived return to human capital and higher income uncertainty both lead to higher fertility, all e...
