The book assumes minimal knowledge of statistics, and no previous knowledge of demography. The authors have developed a set of R packages implementing the methods. Data and code for all applications in the book are available on www.bdef-book.com.
This book will be welcome for the scientific community of forecastersas it presents a new approach which has already given important results and which, in my opinion, will increase its importance in the future. ~Danie
