The Statistical Abstract of the United States, published since 1878, is the standard summary of statistics on the social, political, and economic organization of the United States. It is designed to serve as a convenient volume for statistical reference and as a guide to other statistical publications and sources. The latter function is served by the introductory text to each section, the source note appearing below each table, and Appendix I, which comprises the Guide to Sources of Statistics, the Guide to State Statistical Abstracts, and the Guide to Foreign Statistical Abstracts.

Genealogists and other historical researchers have valued the first two editions of this work, often referred to as the genealogist's bible."" The new edition continues that tradition. Intended as a handbook and a guide to selecting, locating, and using appropriate primary and secondary resources, The Source also functions as an instructional tool for novice genealogists and a refresher course for experienced researchers. More than 30 experts in this field--genealogists, historians, librarians, and archivists--prepared the 20 signed chapters, which are well written, easy to read, and include many helpful hints for getting the most out of whatever information is acquired. Each chapter ends with an extensive bibliography and is further enriched by tables, black-and-white illustrations, and examples of documents. Eight appendixes include the expected contact information for groups and institutions that persons studying genealogy and history need to find. ""

The decennial Census is the US Government's largest statistical undertaking, and it costs billions of dollars in planning, execution, and analysis. From a statistical viewpoint, it is critical because it is the only database that maps every inhabitant into a geographic location. By constitutional mandate, census data are the basis for reapportioning the House of Representatives and the Electoral College. The states use census data to redistrict their state legislatures and often to redraw boundaries for local elections. Census data inform the distribution of over $1.5 trillion in federal funding during the decade. This book details the fundamentals and significance of the 2020 Census for the non-specialist reader. It covers why the Census is the only statistical activity required by the US Constitution, the challenges of working towards an accurate and complete count, and what political ramifications flow from this process. Concise, timely, and comprehensible, this book provides helpful real-life examples while also offering an overview of the entwined statistical and political issues that surround the Census.
