Historical population of Cornwall from 1570 to 2016
Population values from 1570 to 1791 are those estimated by John Rickman.
Rickman based his estimates on the annual totals of baptisms, burials, and marriages collected
in the 1801 census. Annual totals were asked for various years in the eighteenth
century. These estimates were published in 1802. In 1836 he asked incumbents for annual totals
for three-year periods for 1570, 1600, 1630, 1670, 1700, and 1750 and estimates were
published for these years in 1842.
Values for the census years of 1801 to 2011 are from the census.
Recent values for non-census years are estimates from the Office of National Statistics
Earlier population estimates
1086: 29,532 (from Domesday book)
1348: 108,000 (peak population immediately prior to the Black Death)
During the early 1800's there was a devastating collapse in the Cornish economy resulting
in a mass emigration called the
Cornish Diaspora It is estimated that 250,000 Cornish migrated abroad
between 1861 and 1901 with miners making up a large portion.
It is estimated that there are approximately six million persons worldwide with
Cornish ancestry of which fewer than 10% live in Cornwall.
