Since just 2006 school children in Cornwall have rightly been allowed to record themselves (or via their parents for the younger ones) as ‘ethnically’ Cornish or at least identifying as Cornish, on the annual Schools Census - the Census and Pupil Level Annual Schools Census (PLASC).
Since then the number identifying as Cornish has risen from 24% to 51.1%
2006: 24 percent
2007: 27 percent
2008: 30 percent
2009: 34 percent
2010: 37 percent
2011: 41 percent
2012: 43.2 percent
2013: 46 percent
2014: 48 percent
2015: 49.5 percent
2016: 50.6 percent
2017: 51.1 percent
This bodes well for the future.
