Talk by M. M. Postan ,
Professor of Economic History in the University of Cambridge
Since 1801 a census of the population has been taken at fairly regular intervals in the British Isles, and from the evidence provided it has been possible to study the changing size of the community in increasing detail over the past ISO years. The problem of determining the size of the population in the centuries before the regular operation of the census is more complex but no less important. In this talk Professor Postan describes the rise and fall of population through the earlier periods of English history.
