Census and Social Structure [PDF ebook] 

First Published in 1978. The census of population is a key source for any study of nineteenth-century England. In association with parish registers and, from 1837, the civil registers recording births, deaths and marriages, population numbers and trends, the essential dynamic basis of population analysis, may be studied. For the present day student they are an incomparable storehouse of data for the historian and social scientist; indeed in almost any study of the nineteenth century we must sooner or later turn to the census for information.
