Anecdotally from an Irish dermatologist - the majority of her clients under 30 are holiday sunburn casualties from either Iberian waterparks or activities like snorkeling/skin-diving in SEA. The ones over 30 are basically all farmers.
She has her entire family wearing SPF20 24/365, constantly reminding me 'it's the overcast days that actually do the long-term damage'.
