Rethinking of Age and Aging

Population Bulletin vol 63, No. 4 2008 Rethinking Age and Aging
This Population Bulletin illustrates how to use new measures of population aging that take into account changes in longevity over time and place. None of the usual indicators of aging available adjust for increases in life expectancy. With advances in health and life expectancy, measuring population aging presents a problem to demographers because the meaning of the number of years lived has changed. New measures described in this Population Bulletin take life expectancy differences into account. First, we discuss the surprising history of life expectancy change within the last 150 years. Because of increases in life expectancies, it is misleading to compare those who are chronologically age 40 today with people who were 40 a century ago. Second, we introduce the concept of “prospective age” as a way to compare people who live in periods and places where life expectancies differ. Finally, we build on the concept of prospective age in developing alternative definitions of median age, the elderly population, and old-age dependency ratios.

Cyberseminar on “Theoretical and Methodological Issues of the Analysis of Population Dynamics and Supply Systems”

Cyberseminar on “Theoretical and Methodological Issues of the Analysis of Population Dynamics and Supply Systems”2-13 February 2009

The Population-Environment Research Network (PERN) invites you to participate in this upcoming cyberseminar organized in collaboration with the Institute for Social-Ecological Research (ISOE) to examine the theoretical and methodological aspects of research into the population-environment nexus. The starting point in this seminar is an interdisciplinary, social-ecological approach to population dynamics which allows structuring the nexus of population, environment and society in theoretically and methodologically novel ways. It focuses on the interactions among demographic changes and supply systems such as water, food, and energy. The approach seeks to be applicable to different population dynamics (e.g. migration, population growth and decline, urbanization, household structures), as well as to different socio-economic and cultural contexts.

Troubling Trend in Teen Birthrates Seen in New Federal Government Data

From the Guttmacher Institute

From the early 1990s through the early 2000s, rates of teen pregnancy, birth and abortion in the United States all declined dramatically—primarily but not exclusively because of increased and more effective contraceptive use among sexually active teens. These declines have since stalled, however, and new data from the Centers for Disease Control and Prevention’s National Center for Health Statistics (NCHS) indicate that teen birthrates are on the rise. NCHS reports a 3% national increase between 2005 and 2006 (from 40.5 to 41.9 births per 1,000 females aged 15–19). This trend is reflected in data from the Youth Risk Behavior Survey that show recent-year declines in both teens’ contraceptive use and their delaying of first sex.
