As globalization and migration intensified in the late 20th century, many Ngwa families established roots abroad, particularly in the U.S., Canada, and the U.K. These diaspora communities, like the Oha Ngwa Canadian Association in Ontario, continue to serve as cultural custodians.
These associations play a pivotal role in preserving traditions by hosting cultural festivals, offering language classes, and organizing community outreach. They also act as support systems for newcomers and work towards the socio-economic upliftment of underprivileged people back in Nigeria.
The rise of Ngwa professionals abroad has also led to transnational partnerships, including scholarships, health missions, and vocational training programs, empowering the next generation both at home and abroad.
