NOTE.—The population of each Census, except 1801-1831 inclusive, includes all members of the Home Defence Forces, and, except for 1841, persons in the Naval and Merchant Service on board vessels in port on Census night or arriving the following day. For 1931, however, the figures include persons on board vessels in port or at moorings or anchorage, in England and Wales, or engaged in a coastwise or fishing voyage and arriving within a fortnight following the Census day.

* In computing the decennial rate of increase the varying lengths of the intercensal periods have been taken into account, and the rates for the periods 18311841 and 18411851 have been further corrected by the exclusion of the Army, Navy and Merchant Service from the population for 1841, and of the persons on board vessels from the population for 1851.
