Note that Pitcairn Island isn't 47 sq. km. That's the size of the combined islands in the Pitcairn area - Henderson, Ducie, Oeno and Pitcairn. Pitcairn Island itself is 3.2km long and 1.6km wide.

The population has been in the low hundreds in the past, and population pressure was one of the reasons for the 1831 migration to Tahiti and the 1856 migration to Norfolk.

I agree more information on the website would be good.
