The transcription of the 1940 population census of Guam is a product of the Chamorro Roots Genealogy Project(TM). Like its predecessors previously published, this book begins with an overview and observations of the census in general. However, unlike the previous transcriptions this does not contain a complete transcription of the census sheet. Rather, each census page contains a transcription of select and limited data from what was handwritten and transcribed into a type written format. It continues to serve as a tool to make it a little easier for fellow genealogy researchers during the course of their work.
