The Data file and 14 analysis files are here. A guide to the files is here.
Backmatter of the book available here includes: Appendix A (describes how to download the data from IPUMS-USA, install free R and R Studio software, and use the R scripts and data linked to above). The back also contains a glossary, references to studies that use ACS microdata, and more.
Frontmatter of the book available here includes: table of contents and preface.
This book describes published economics studies which all use the same data source: individual responses to the American Community Survey (ACS), the nation's largest household survey. The author identifies intriguing studies that clearly illustrate core econometric methods--such as regression control and difference-in-differences--and the archived data and code for the book replicates key statistics from the studies. The Appendix to this book contains a guide to using the free R software, downloading the ACS and other public-use microdata, and running the replication files, which assumes no background knowledge on the part of the reader beyond introductory statistics.
By opening up the hood on how top scholars use core econometric methods to analyze large data sets, a motivated reader can use this book to learn not only how to replicate published research, but also to extend the analysis to create new knowledge about important social phenomena.
A more casual reader can skip these online supplements and still gain data-driven insights into social and economic behavior. The book concludes by describing how careful empirical estimates can guide decision making, through cost-benefit analysis, to find public policies that lead to greater happiness while accounting for environmental, public health and other impacts.
With its accessible discussion, glossary, detailed learning goals, end of chapter review questions and companion resources, this book is ideal for use as a supplementary volume in introductory econometrics or research methods courses.

Update: Since the book’s publication, I have written several articles that extend its themes and will be of interest to readers. In The American Economist, I describe the term paper assignment I use in my class, providing a concrete example of the “replicate and extend” pedagogical approach developed in the book. My article in Contemporary Economic Policy integrates the material from Chapters 2 and 7 by applying replication estimates from a regression model in a formal Cost-Benefit Analysis (CBA). In addition, two other recent studies—each with archived data and transparent R code—offer further opportunities for learning econometrics and working with the ACS. For all of these projects, I have followed the same open and transparent coding practices established in Data and the American Dream.

Below I include links to three studies, the published and working paper versions (when available), additional replication files (beyond those available in the archived data and code package on Open ICPSR.) I also list the course topics and learning objectives that I use each study to illustrate.
