Barrio and Barangay are both the same. Almost all people in our country lives in Barrio or Barangay.
If they moved to subdivisions first class nor any class, you still live in a Barangay or Barrio because all subdivisions and first class village location is in the Barangay or Barrio.
Even people from highlands lives in Barangay.
All our regions are composed of towns/city and they our composed of Barangays.
I usually call them indigenous peoples and I love to speak with them about their culture.
