Hiruhimangraw:Ilocos nga Rehiyon
"Ilocos" is an ethnocentric term predominantly used and promoted by the Ilocanos. There are other ethno-linguistic groups in the region such as the Pangasinan and the Bolinao. The ethno-neutral term would be "Northwestern Luzon Region".
Thank you for correcting the term. The Pangasinan people appreciate the correction.
