Book excerpt: This book presents new insights into the consequences of the impending growth in and impact of the older segment of Latino aging adults across distinctive regions of the Americas. It uses a comparative research framework to further understanding of current issues in health and aging in the transnational context of the health and migratory experiences of the U.S.- Mexican population. It provides an important contribution to the interdisciplinary investigation of chronic diseases and functional impairments, social care and medical services, care-giving and intervention development, and neighborhood factors supporting optimal aging, using new conceptual and methodological approaches (inter-group comparisons). Specifically, the chapters employ different methodologies that investigate trends in aging health and services related to immigration processes, family and household structure, macroeconomic changes in the quality of community life, and focus on the new realities of aging in Latino families in local communities. The book focuses on measurement, data-quality issues, new conceptual modeling techniques, and longitudinal survey capabilities, and suggests needed areas of new research. As such it is of interest to researchers and policy makers in a wide range of disciplines from social and behavioral sciences to economics, gerontology, geriatrics, and public health.
