"This book is destined to become the go-to text for people wanting to use R for the analysis of US Census data. I think this is a strong, clear, and comprehensive introduction to the tidycensus package and the tidyverse. I have been using tidycensus and Walker’s tigris package probably since he initially contributed them to the community of R users years ago. Although I use the packages regularly for teaching and research, I still learned quite a bit about their functionality in the chapters I reviewed. Thus, I think it will be a useful text for both novices and experienced R users. I could see this book being used in a variety of social science courses relating to research methodology, data visualization, and cartography."

"Walker [...] is clearly familiar with the material and how to use R to the best advantage for mapping and modeling. Indeed, he has written the code for some of the many R packages covered in this title. In this book, he recommends which R package is most suitable for each application and then provides code examples to highlight how to carry out a simple version of each task with the package. Some of the specific scenarios include the creation of data visualizations using ggplot2 or tmap, a discussion of handling margins of error with the American Community Survey data using tidycensus, and historical census data analysis and mapping using ipumsr. The code samples are suitable for users who are quite familiar with R or similar GIS software. This title would function well as a reference or a textbook for graduate-level students or faculty.
