Environmental Geology : Handbook of Field Methods and Case Studies
As earth’s population continues to grow and the detrimental aftereffects of industrialization and environmental negligence become more apparent, society has become more aware of, and concerned about, stewardship of the natural environment – water, soil, and air. Sustainable development has become more widely received and promoted in many parts of the world. The need is now critical for earth and environmental scientists and engineers to work together to implement technologies that can preserve our environment. The Earth’s population was 6.6 billion as of April 2007 according to the U.S. Census Bureau. This number is expected to rise to 9.4 billion by 2050. The population is increasing the demand for natural resources and energy, and increasing stress on the environment. Thus, protection of the environment and remediation of damage to the environment must be a priority. It is also important to develop procedures that will help to avert further damage to the environment and to recognize as early as possible the risks associated with changes in the environment. Many methodologies and technologies have become more advanced in the past few decades, and new technologies and approaches have been developed, all to address the growing need for environmental assessment, monitoring, and remediation. As these technologies have grown, the need for interdisciplinary cooperation has also become more apparent.
Differential Undercounts in the U.S. Census : Who is Missed?
This 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. In addition to focusing on measuring census coverage for several demographic characteristics, including age, gender, race, Hispanic origin status, and tenure, it also considers several of the main hard-to-count populations, such as immigrants, the homeless, the LBGT community, children in foster care, and the disabled. However, given the dearth of accurate undercount data for these groups, they are covered less comprehensively than those demographic groups for which there is reliable undercount data from the Census Bureau. This book is of interest to demographers, statisticians, survey methodologists, and all those interested in census coverage.
