SYNOPSISThis tutorial describes demographic changes and their implications for parent ing and parent -child relationships. First, we discuss 2 major sociodemo graphic changes -declining fertility and increasing longevity -from the point of view of social demography. Second, we elaborate on implications of de mographic changes for parenting and intergenerational relationships from so ciolOgical and psychological perspectives. This discussion of parenting and parent -child relationships addresses changes from a life-span perspective, tak ing into account contextual factors. Finally, we present examples of empirical investigations of relations among sociodemographic changes, parenting, and parent -child relationships.
INTRODUCTIONMost developmental analyses of parent -child relationships focus on in teractions and conditions within the immediate family. The predominant view in the field, however, is that social changes, such as changes in family size and in individuals' life-spans, uniquely impact family life. These so cial changes offer a means by which to describe those historical shifts that result in cultural differences. However, the nature of these changes, includ ing the ways in which they have been approached by social demographers and how these changes may affect parenting and parent -child relation ships, has not yet been adequately delineated. At issue are the ways in which parent -child relationships may be affected, the kinds of research that should be undertaken, and which theoretical models might be used to guide research. This tutorial is a step toward filling these gaps. It begins with a description of what demographers refer to as "the demographic transition" and then proceeds to consider implications of the demographic transition for the nature of parenting and parent -child relationships in various cultural contexts.
THE DEMOGRAPHIC TRANSITIONThe demograph ic transition is a process that is observed worldwide and has been described by historical and internation al comparativ e demogra phy. This description is based on a model according to which the first phase of the demograph ic transition is characterize d by a multistep pro cess of modernizat ion and adaptation. The starting point is a relatively sta ble state of high mortality with simultaneo us high fertility. Especially be cause of high infant mortality and a relatively stable mortality risk across all other stages of the life-span, high fertility does not result in a significant change in population size, but rather in fast turnover. The second phase of the transition is characteriz ed by an initial increase in mean life expectancy without a simultaneo us decrease infertility, which results in population increase. In the third phase, fertility rates decrease to a similar extent such that in the fourth phase a new equilibrium is reached based on low mortal ity and low fertility with a resulting slow population turnover (see Figure 1). As far as the first three stages are concerned , the model of the demo graphic transition provides a rath...
