The Problem,roceed very irregularly and no longer connect the few estimates of early population to the known totals of the nineteenth and twentieth centuries in a smooth logistic curve, there remain many wide areas of uncertainty, even about some of the key periods of that growth.

A very elaborate recalculation was made by Brownlee in 1915–16, while Griffith prepared another set of figures for his study of English population of 1926. In 1929 Marshall proposed some modifications to the estimates of Farr and Brownlee. Since then Ohlin (1955)

Mortality,was capable of fluctuating violently in the short run in addition to shifting perceptibly in the long run. For this reason, if for no other, estimates derived from the . are even less reliable for mortality than for fertility, since before 1780 the totals of burials relate to single years in which m

The Problem,It has not always been so. When Gregory King made the first scholarly estimate of the number of inhabitants at the end of the seventeenth century there were about one-ninth of today’s numbers; at the time of Domesday there may have been a mere one-fortieth. How and why the population increased on th

The Chronology of Growth,ot be established with any exactitude. But because the establishment of a chronology of growth has seemed to demand some priority, a great deal of the scholarly energy put into the study of British population history has, until recently, been directed to this problem.
