Volume I of a two volume compilation which reviews the evolution of the census, including what data and definitions were chosen initially, and how the census developed over the years into a reliable tool which allowed analysts to develop data points by decade. Following an introduction (which includes b&w illustrations of towns and people), facsimile reproductions present census information from 1821 through 1851 that reveals where the Irish had their homes, how they made their living, what kind of an education they received, where they worshipped, and how long they lived. 10.75x14".
