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.

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 book presents a rigorous enquiry into life course processes that are thought to influence health, integrating the latest methodologies for the study of pathways that link socio-demographic circumstances to health with an emphasis on the mediating factors that lie on these pathways. Following an introductory chapter on the application of formal mediation methods within the life course framework, the book offers insights on the pathways that link early life socio-economic circumstances to physical activity in later life, the role of physical activity as a moderator and/or mediator of the association between fertility history and later life health and the evolution of self-rated health over the life course in two generations born 12 years apart in 20th century Britain. Pathways to Health presents a dynamic view on how to investigate specific hypotheses within the life course framework and enhances the ability of the social science community to investigate specific mechanisms related to public health interventions.

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.

It traces the demographic consequences of the change from a relative balance between central city, minor urban centres and dispersed rural population within each functional region in 1947, to one of extreme central city dominance by 2011, and examines the long-term implications of these changes for regional policy.

This book analyses the reasons for relying on behavioural contraception methods among urban 'elites' in India and examines their efficacy in controlling fertility.

Combining statistical analyses and personal interviews, this book examines the phenomenon of adult children in the United States who have returned to living with their parents in the family home.

This book tells the story of how a group of far-sighted, academic researchers came to the aid of an overwhelmed local government. It details the history of the Washington State Census Board, which began in 1943 as part of an emergency measure during a massive wartime in-migration. The narrative also shows the demographic legacy of the Board and, ultimately, provides an unforgettable look into the creation and evolution of applied demography.Inside, readers will discover how Washington State struggled to keep up with the unexpected needs for housing, transportation, schools, and public utilities for the hundreds of thousands of migrants who came to work in industries that practically developed overnight with the mobilization for World War II. The author recounts how Professor Calvin F. Schmid, who led the Washington State Census Board, and his team developed methods of population estimation that are still in use today.In the process, the narrative reveals how populationfigures were gathered, compared, and projected at a time when the hand calculator was considered cutting-edge technology. The book also details how methods were refined and improved over time as well as how those involved developed new ways to obtain and, more importantly, utilize the information. With the aid of archived materials, personal interviews, and rich personal accounts, this book will inform and inspire practicing and academic demographers as well as planners, policy-makers, historians, and interested readers.

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.

This comparative study of European time transfers reveals the full extent of transfers in the form of unpaid work and highlights the existence of important gender differences in household time production.

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.
