Demographic Research Monographs - Böcker

This open access book describes methods of mortality forecasting and discusses possible improvements. The different parts of the book provide discussions of current practice, probabilistic forecasting, the linearity in the increase of life expectancy, causes of death, and the role of cohort factors.

They will also see applications of sensitivity analysis to population growth rates, stable population structures, reproductive value, equilibria under immigration and nonlinearity, and population cycles.

In contrast to previous assertions about a ceiling on the human lifespan, evidence presented in this book suggests that lifespan records in specific countries and globally will be broken again and again as more people survive to become supercentenarians.

As demonstrated in this book, some demographic techniques can also be seen as theoretical models, and some substantive/behavioral models, commonly rejected as theory because of inconsistent observations, are now seen as valuable theoretical models, for example demographic transition theory.

Inverse Projection is a method for estimating accurate demographic indicators of a population where vital registration data are available, but population censuses are lacking or unreliable. The book offers an overview of the present state of methodological development in the field of inverse projection techniques. In the various chapters of the book, leading experts in demography and related fields review the method, discuss recent extensions, test performances, and stress differences of the various procedures. The book is intended for all scientists who are interested in the reconstruction of demographic scenarios in particular situations, with specific kinds of data, as well as for statisticians and mathematicians who are attracted by this fascinating field of application.

The monograph demonstrates the widespread existence of differences in life span by month of birth in the elderly populations of contemporary societies. It provides evidence that the pattern is linked to the seasons of the year, by comparing the Northern and the Southern Hemisphere. It formulates and tests a series of explanations for the month-of-birth effect and rejects many of the most frequently offered explanations. In particular, it rejects those that attribute the month-of-birth effect to social or statistical confounding. It establishes a link between the month-of-birth pattern in the life span and the month-of-birth pattern in survival during the first year of life. It provides evidence that nutrition and infectious disease early in life play an important role in adult health and survival later in life and that the differences in life span by month of birth still exist in cohorts born today.

Seasonal fluctuations in mortality are a persistent phenomenon across populations. This does, however, not explain why in colder countries the differences between winter and summer mortality are smaller than in countries with warm or moderate climate.

Aging is inevitable: this is gerontological dogma. And humans do inevitably grow old, which is probably why it seems so unlikely to us that other forms of life could escape aging. Escaping aging is not escaping death. Death is an inherent part of life, and it can strike any time. But the question is whether death necessarily becomes more likely as life proceeds. And it does not. The theoretical results in this monograph indicate that life provides alternative strategies. While some organisms will deteriorate over adult ages, for others mortality appears to fall or remain constant, at least over an extended period of life after reproductive maturity. This is empirically observed especially for species that keep on growing during adult ages. Perhaps the diversity of aging matches the diversity of life. My thesis, the central insight of this monograph, is: to deeply understand why some species age it is necessary to understand why other species do not.

How should life expectancy be calculated? More generally, how should life - bles be estimated? Since John Graunt's pioneering contribution, read before theRoyalSocietyofLondonat6p. m. onthe27thofFebruary1661,demog- phers have developed better and better methods. Some concerns were raised, including concerns about how to deal with heterogeneous populations p- lished in an article inDemography in 1979 that I wrote with Kenneth Manton and Eric Stallard. Yet, a few years ago nearly all demographers believed that as long as the underlying population and death counts were accurate, then lifetables could be reliably estimated. John Bongaarts and Gri? Feeney launched a revolutionary assault on this dogma. Two key contributions by them are reprinted in Part I of this mo- graph. Some very good demographers agreed, as least in part, with B- gaarts' and Feeney's radical argument that when death rates are changing, then tempo e?ects distort conventional calculations of life expectancy. Other very good demographers disagreed.So John Bongaarts and I brought some leading demographers together in a research meeting, co-sponsored by the Max Planck Institute for Demographic Research and the Population Co- cil and held in New York City on November 18 and 19, 2004. Many of the papers discussed at the workshop, generally after considerable revision, were published in Demographic Research in 2005 and 2006. Nine of these articles, in some cases somewhat revised, are published in this monograph: they are the ?rst seven chapters in Part II and the two chapters in Part III.

This volume, “Fertility of Immigrants: A Two-Generational Approach in Germany” by Dr. Nadja Milewski, is the sixth book of a series of Demographic Research Monographs published by Springer Verlag. Dr. Milewski is now working for the University of Rostock, but at the time she wrote the book, she was a research scientist at the Max Planck Institute for Demographic Research. The book is a slightly-revised version of her doctoral dissertation (“Fertility of Immigrants and Their Descendants in West Germany: An Event History Approach”), which she completed at the Max Planck Institute and submitted to the University of Rostock. She was awarded highest honors, summa cum laude, for her dissertation. As Professor Jan Hoem wrote in his review of Dr. Milewski’s dissertation, the research focuses on the patterns and levels of childbearing among immigrant women. Given Germany’s varied immigration experience with refugees, asylum seekers, guest workers, and foreign-born persons of German ancestry, Dr. Milewski’s topic is of particular interest, especially with regard to differences in the patterns and levels of childbearing among various kinds of immigrants to Germany vs. native-born Germans. Numerous empirical and theoretical studies of childbearing among immigrants to various countries have been published and Dr. Milewski carefully reviews them. While earlier studies have tended to be rather fragmentary, particularly for European populations, Dr. Milewski’s research provides a comp- hensive picture of the recent female fertility of post-war migrants and their desc- dants in West Germany, with an emphasis on migrants who came to Germany to work.

Does human mortality after age 110 continue to rise, level off, or start to decline? The sixteen chapters of this book discuss age validation of exceptional longevity, data on supercentenarians in a series of countries, structure and contents of the IDL, and statistical analysis of human mortality after age 110.

Tommy Bengtsson Population ageing, the shift in age distribution towards older ages, is of immense global concern. It is taking place to a varying degree all over the world, more in Europe and some Asian countries, less on the African continent. The worldwide share of people aged 65 years and above is predicted to increase from 7. 5% in 2005 to 16. 1% in 2050 (UN 2007, p. 11). The corresponding ?gures for developed countries are 15. 5 and 26. 2% and for developing countries 5. 5 and 14. 6%. While population ageing has been going on for some time in the developed world, and will continue to do so, most of the change is yet to come for the developing world. The change in developing countries, however, is going to be much faster than it has been in the developed world. For example, while it took more than 100 years in France and more than 80 years in Sweden for the population group aged 65 and above to increase from 7 to 14% of the population, the same change in Japan took place over a 25-year period (UN 2007, p. 13). The scenario for the future is very similar for most developing countries, including highly populated countries like China, India and Brazil. While the start and the speed differ, the shift in age structure towards older ages is a worldwide phenomenon, stressing the signi?cance of the concept global ageing.

Does human mortality after age 110 continue to rise, level off, or start to decline? This book describes a concerted, international research effort undertaken with the goal of establishing a database that allows the best possible description of the mortality trajectory beyond the age of 110. The International Database on Longevity (IDL) is the result of this ongoing effort. The IDL contains exhaustive information on validated cases of supercentenarians (people 110 years and older) and allows unbiased estimates of mortality after age 110. The main finding is remarkable: human mortality after age 110 is flat at a probability of death of 50% per year. The sixteen chapters of this book discuss age validation of exceptional longevity, data on supercentenarians in a series of countries, structure and contents of the IDL, and statistical analysis of human mortality after age 110. Several chapters include short accounts of specific supercentenarians that add life to demographic research.

Mathematical demography is the centerpiece of quantitative social science. The founding works of this field from Roman times to the late Twentieth Century are collected here, in a new edition of a classic work by David R. Smith and Nathan Keyfitz. Commentaries by Smith and Keyfitz have been brought up to date and extended by Kenneth Wachter and Hervé Le Bras, giving a synoptic picture of the leading achievements in formal population studies. Like the original collection, this new edition constitutes an indispensable source for students and scientists alike, and illustrates the deep roots and continuing vitality of mathematical demography.

The Ukraine faced two very different kinds of health crises during the twentieth century. First, in the 1930s and 1940s, famine, war and political upheaval caused massive population losses. Previous evaluations of overall losses have given an idea of the scale of these catastrophes but do not distinguish between crisis mortality, birth shortfall and loss through emigration. Based on a painstaking work of reconstitution, this study is the first to provide a detailed estimation of the hecatomb in terms of number of deaths and life expectancy. The famine of 1933 was alone responsible for the deaths of 2.6 million Ukrainians and reduced male and female life expectancies to 7 and 11 years respectively. Once the crises of the 1930s and 1940s were over, the earlier trend in health resumed and mortality declined steadily until the 1960s. At this point, however, a new type of crisis appeared that caused a sustained reversal in the existing trends. Life expectancy for women stopped increasing altogether, while that for men began a relentless year on year regression. Notwithstanding the confusing picture created by the fluctuations of the 1980s and 1990s, the long-term trend is to further deterioration. To understand the factors involved, this study analyses in detail the combined effects of different causes of death at different ages.​

Regional mortality differences are one dimension of health inequalities, but its trends and determinants in Germany are widely unknown. This book examines and illustrates patterns of regional mortality in Germany—with focus on small-area differentials—and their changes over time. It identifies explanatory factors at individual and regional level. Mortality differences between eastern and western Germany exist, but small-area mortality differentials are often greater. Though the main spatial mortality patterns remain, this study provides evidence that some distinct changes in the small-area mortality patterns in Germany—especially among women—occurred within a short period of time. Mortality inequalities at younger ages and in behavior-related causes as well as differences in socioeconomic conditions contribute strongly to regional mortality differences in Germany. The book shows that the complex interplay between individual- and regional-level mortality risk factors requires a multidimensional approach to reduce regional mortality inequalities.

Military recruitment will become more difficult in times of demographic aging. The question arises whether demographic change will constrain the capacity of aging states like Germany to conduct foreign policy and pursue their national security interests. Since contemporary military operations still display a strong human element, particular scrutiny is given to the empirical analysis of the determinants of military propensity and military service among youth. An additional human capital projection until 2030 illustrates how the decline in the youth population will interact with trends in educational attainment and adolescent health to further complicate military recruitment in the future. A concluding review of recruiting practices in other NATO countries provides insight in best-practice policy options to reduce the military’s sensitivity to demographic change. Following this approach, the book gives prominence to a topic that has thus far been under-represented in the greater discussion of demographic change today, namely the demographic impact on international affairs and strategic calculations.
