In order to ensure that population density did not skew migration figures to Latin America from each sub-registration district, these were calculated against the total population of each in 1871, the decade before population started to decline markedly. Only Gwennap, Redruth and Camborne, in that order of significance, were statistically visible. The top four Latin American receiving regions: Mexico, the Pacific Littoral, Brazil and Cuba, have been selected and the migration flows to these regions compared with flows from the top three sub-registration districts in Cornwall. Two of these, Camborne and Redruth, are parishes in their own right but Gwennap includes Stithians which, with a population that was about three times smaller than Gwennap’s in the mid nineteenth century, represents a mere 4 per cent of migration from the sub district of Gwennap. The migration flows from all three districts are extremely varied; this is all the more surprising when we consider that the four parishes that comprise the sub-districts in question cover an area of around 10 square miles.
migration from Gwennap to the Pacific Littoral accounts for almost half of
the total migration from this sub-district to all seven Latin American
regions, it sends a mere 3 per cent to Cuba. However, neighbouring Redruth
sends only half the number of migrants to the Pacific Littoral as Gwennap,
but the figure for migration to Cuba from Redruth, the sub-district that
sends the majority of Cornish migrants there, is over eight times higher
than that of Gwennap. A similar complex picture emerges for migration to
Mexico that accounts for a staggering 66 per cent of all migration to
Latin America from Camborne, yet Gwennap sends less than half this number,
while Redruth sends around five times less. Camborne is the sub-district
from which the majority of Cornish migrants to Mexico originated, with
Gwennap next in order of significance.
