In every developed country, the economic transition from pre-industrial stagnation to modern growth was accompanied by a demographic transition from high to low fertility. Even though the overall pattern is repeated, there are large cross-country variations in the timing and speed of the demographic transition. What accounts for falling fertility during the transition to growth? To answer this ...

This paper explores the role of geography in economic development and demographic transition. It presents a growth model where survival is endogenously determined and where the odds of survival and the returns to labor are higher in geographically favorable regions. Higher life expectancy prompts parents to devote more of their resources to old-age consumpion and enjoyment. Consequently, they i...

Background: The study aimed to evaluate the interval between first drug use and regular injection and factors associated with transition from first injection into premature regular injection among people who inject drugs (PWIDs).Methods: In a multicenter cross-sectional study, we recruited 400 PWIDs using snowball sampling. Age of first drug use, age of initiation of regular injection, and demo...

The identification of the characteristics that have an influence on the vaccination coverage of children and the determination of the pattern of such influence are very important since the government can reschedule the policy to immunize each and every child. This paper examines the factors that manipulate the vaccination coverage in terms of five major vaccines using the Bangladesh Demographic...

Most work on the human fertility transition has focused on declines in mean fertility. However, understanding changes in the variance of reproductive outcomes can be equally important for evolutionary questions about the heritability of fertility, individual determinants of fertility and changing patterns of reproductive skew. Here, we document how variance in completed fertility among women (4...

The Agricultural Revolution accompanied, either as a cause or as an effect, important changes in human demographic systems. The consensus model is that fertility and mortality increased and health declined with the adoption of agriculture, compared to those for hunter-gatherers. Analysis of the agricultural transition relies primarily on archaeological and paleodemographic data and is thus subj...

in countries that comprise the majority of the world’s population, the demographic transition has now reached its putative endpoint: a state marked by low fertility and low mortality. it is expected that the rest of the world’s countries are headed in the same direction, prompted by modernizing social change and nudged by looming physical constraints. what were the roles of deliberate policies,...

In most mammals, and in the majority of traditional human societies for which data exist, status, power, or resource control correlates with lifetime reproductive success; male and female patterns differ. Because such correlations are often argued to have disappeared in human societies durmg the demographic transitton of the nineteenth century, we analyzed wealth and lifetime reproductive succe...

References to the second demographic transition (SDT) concept/theoretical framework have increased dramatically in the last two decades. The SDT predicts unilinear change toward very low fertility and a diversity of union and family types. The primary driver of these changes is a powerful, inevitable and irreversible shift in attitudes and norms in the direction of greater individual freedom an...

Advanced economies undergo three transitions during their development: 1. They transition from a rural to an urban economy. 2. They transition from low income growth to high income growth. 3. Their demographics transition from initially high fertility and mortality rates to low modern levels. The timings of these transitions are correlated in the historical development of most advanced economie...
