This book demonstrates that population structure and dynamics can be reconstructed by stochastic analysis. Population projection is usually based on age-structured population models. These models consist of age-dependent fertility and mortality, whereas birth and death processes generally arise from states of individuals. For example, a number of seeds are proportional to tree size, and amount of income and savings are the basis of decision making for birth behavior in human beings. Thus, even though individuals belong to an identical cohort, they have different fertility and mortality. To treat this kind of individual heterogeneity, stochastic state transitions are reasonable rather than the deterministic states. This book extends deterministic systems to stochastic systems specifically, constructing a state transition model represented by stochastic differential equations. The diffusion process generated by stochastic differential equations provides statistics determining population dynamics, i.e., heterogeneity is incorporated in population dynamics as its statistics. Applying this perspective to demography and evolutionary biology, we can consider the role of heterogeneity in life history or evolution. These concepts are provided to readers with explanations of stochastic analysis.

This open access book provides an overview and analysis of the causes and consequences of the massive and highly consequential transition in reproductive behaviour that occurred in Asia, Latin America, and Africa since the mid-20th century. In the 1950s contraceptive use was rare and women typically spend most of their reproductive years bearing and rearing children. By 2020 fertility and contraceptive use in Asia and Latin America reached levels commonly observed in the developed world. Africäs fertility is still high, but transitions have started in all countries. This monograph is the first to provide a comprehensive analysis of these trends and their determinants, covering changes in reproductive behaviour (e.g., use of contraception and abortion), preferences (e.g., desire to limit and space births) and the role of socioeconomic development (e.g., education). The role of government policies and in particular family planning programs is discussed in depth. Particular attention isgiven to provide a balanced assessment of several political and scientific controversies that have beset the field. As such this book provides an interesting read for a wide audience of undergraduate and graduate students, researchers, and public health policy makers.

The book comprises three chapters, with each chapter assigned various type data such as time series data, cross sectional data and panel data. The second is that time series analysis such as the Bayesian vector autoregressive (BVAR) model or co-integration concepts is applied to explore the determinant factors of fertility.

This book represents a first attempt to comprehensively discuss and investigate causes and potential implications of changing patterns of spouse pairing in Japan and to consider similarities and differences with patterns observed in the USA and other low-fertility Western societies.

This book provides an insightful sociological study of the shrinking Japanese population through a regional variation perspective as it varies significantly by municipality, even within the same prefecture.

This open access book provides a step-by-step overview on how to build a microsimulation model with SAS. The book also describes how to adapt the model for other countries or other purposes. It also provides details on how to extend and adapt the model for other purposes as well as other use of microsimulation with SAS.

This book looks at how Australia's migrant population composition is likely to change over coming decades. These projections indicate a massive shift in Australia's migrant composition from a European to an Asian-dominated population over the coming decades-a change which can be interpreted as a third demographic transition.

This book provides an insightful sociological study of the shrinking Japanese population through a regional variation perspective as it varies significantly by municipality, even within the same prefecture.

This book describes the low fertility status in three developed Asian countries-Japan, South Korea, and Singapore-and outlines countermeasures for their declining birthrates.

This book focuses on the links between family, education, and employment systems in the Asian developed economies, proposing that these three systems and their interrelations are powerful factors causing the low fertility in Asia.The phenomenon of low fertility has been widely observed in developed countries, and the birthrate in Asian countries is among the lowest in the world. Although these countries have implemented measures to counter the falling birthrate, the expected effect has not yet been achieved. Moreover, Asia has seen a rapid decrease in the number of marriages. To promote effective countermeasures, it is necessary to clarify the factors influencing the low birthrate and decline in the number of marriages. Based on a statistical analysis of survey results mainly from Japan, South Korea, and Singapore, this book discusses several important points. First, because the family system is strong, cohabitation and children born to single mothers are not socially accepted. Further, mothers play a strong role in fulfilling expectations for children's education. Second, the popularization of higher education and intense academic competition, which have been a driving force for rapid economic growth, have led to many parents opting to have fewer children, as the cost of education is high. Lastly, wage disparity is large and employment stability is a matter of concern. These factors increase competition within education and, in turn, make it difficult for the young generation to choose marriage. Within the employment environment, balancing work and family life is problematical, especially for women.

This monograph outlines an integrative framework that conceptualizes the role of relations of control in human reproduction and long-term population dynamics.

This principle of sustainable population indicates that the demographic transition must follow a logistic curve.Using a system dynamics approach, the author constructs a simulation model based on four major loops: fertility, reproduction timing, social capital accumulation, and lifespan.

This open access book describes the differences in US census coverage, also referred to as "differential undercount", by showing which groups have the highest net undercounts and which groups have the greatest undercount differentials, and discusses why such undercounts occur.

This book interprets and explains contemporary population issues from historical and cultural perspectives. These include lowest-low fertility in the Republic of Korea and Taiwan, early population aging in China relative to the developmental level, and various modes of domestic and international migration in the region.

This book provides a systematic framework for interpreting the fertility decline in Japan. It situates the change in fertility rates in a broader context, such as family life and working customs. The basic argument it puts forward is that Japan has failed to establish a "dual-earner" society: women still face the trade-off between having a career or starting a family, which has led to an extremely low fertility rate in Japanese society.Further to this rather common explanation, which could also be applied to other low-fertility societies such as Germany and Italy, the author presents an original view. Japan has had its own momentum in holding on to its strong "men as breadwinners and women as housekeepers" model by creating a unique regime, namely, a Japanese model of a welfare society. This regime places special emphasis on the welfare provided by private companies and family members instead of by the government. Private firms are expected to secure men's jobs and income to the greatest extent, taking advantage of Japanese employment customs. On the other hand, women are expected to provide care for their family members. The book argues that the familialist orientation is still dominant in Japan and is repeatedly reinforced in the policy context.

This book introduces Japan's current policy initiatives directed at eldercare and international labor migration, and, wherever appropriate,it adds a comparative perspective from Germany.

This book describes the development of studies of the family system in Japan and the West, introducing the evolution of the key concept of kin availability. It points out that the concept was first formulated by the Japanese sociologist Teizo Toda in the 1930s to analyze the unexpectedly low frequency of three-generation family households in Japan in the 1920s. The book provides an analytic model proposed by the author in the 1980s, which explains the halt in the decrease in the prevalence of married children residing with their parents in the 1970s and 1980s in Japan. The author maintains that this change was caused not by the breakdown of the nuclearization of the family system, but by a decrease in the availability of parents with whom to co-reside. This model provides a sophisticated measurement of living- arrangement behavior, showing that fewer people in Japan are choosing to co-reside. It can also be applied to regions where there is demographic transition and the stem-family system is maintained to varying degrees. The book shows that a controversy similar to that surrounding the Japanese family was occurring in the West in the 1980s in the context of the then recently discovered scarcity of extended families in seventeenth and eighteenth- century England. It shows that the quantitative historian Steven Ruggles came close to successfully resolving this question using a model based on the concept of kin availability.The book demonstrates that these endeavors in the 1980s yielded a new discipline of family demography both in Japan and the West and that one of the key concepts articulated by the author has taken on practical as well as theoretical significance with regard to the provision of care for the elderly in residing with the generation of children born after the1970s.

After a rapid decline shortly after the war, in which fertility was halved in one decade from 4.5 children per woman in 1947 to 2.1 in 1957, Japan's fertility started to decline to below-replacement levels in the mid-1970s, reaching 1.3 per woman in the early 2000s.

The overarching objective of this book is to summarize, extend, and update previous research on educational differences in family behavior in Japan.

This book presents original data on the proximate determinants of fertility in Japan. Further, it sheds new light on the similarities and differences between the fertility level in Japan and in other countries in terms of biodemographical components, helping readers understand the mechanisms of fertility change in Japan.

Finally, the historical relationships among women's survival rates at reproductive age, the theoretical fertility rate to maintain the replacement level and the recorded total fertility rate (TFR) were analyzed.

Analyzing the relation between population factors and technological progress is the main purpose of this book. The increase in technological progress, which is measured as total factor productivity (TFP), is realized both by improvements in productivity in the short term and by economic developments in the long term.

Through this book, a Japanese economic demographer clearly shows the various economic consequences of population problems in Japan, especially the impacts of continuing ultra-low fertility and the world's highest life expectancy in the post-demographic transition phase.
