The age-specific growth function of an observed population and the reproductive value function based on the population´s current vital rates determine the intrinsic rate of growth implied by those vital rates through the simple relationship given in equation (1). That equation establishes the...

Formal demography has yet to move beyond assuming that demographic rates are constant over time, an assumption that is both unrealistic and constraining. To generalize the fixed rate stable model to the changing rate dynamic model, this paper explores the mathematical regularities that underlie...

Many studies have examined Keyfitz’s population momentum, a special case of inertia in long-term population size resulting from demographic transition to the stationary population growth rate. Yet, population inertia can be produced by any demographic perturbation (i.e., not just perturbations...

Many studies have documented a negative association between macroeconomic indicators and fertility in times of economic crisis. These studies are based on research designs that do not allow for excluding that the observed association is driven by confounders. The aim of the present paper is to...

Scholars have recently become increasingly interested in the role religion plays in the responses to the HIV/AIDS epidemic in sub-Saharan Africa. Here, we present the Malawi Religion Project (MRP), which provides data to examine the relationship between religion and HIV/AIDS through surveys and...

We explore the spatial distribution of orphans in two areas of Malawi. We first review pertinent themes in qualitative data collected in our research sites. Then, using spatial analysis, we show how positive and negative clusters of orphans—which we term orphanhood "hotspots" and...

The Netherlands has seen a considerable decline of the period total fertility rate and delayed childbearing, just like all other European countries. The drop in fertility, however, has not been as sharp as in many other regions of Europe. The period total fertility rate in the Netherlands has...

This paper evaluates the quality of the data collected as part of the Kenya and Malawi Diffusion and Ideational Change Projects, two longitudinal household surveys that examine the role of social networks in influencing attitudes and behavior regarding family size, family planning, and HIV/AIDS...

This article examines changes in network structure using data on conversational networks from the 1998 and 2001 rounds of the Malawi Diffusion and Ideation Change project. The principal aims are to show that network structure can change significantly in relatively short periods - in particular...
