Following the 2011 New Cambria local government reform, the Municipality of Portsea was merged into the Municipality of Averytown. The population of the new, larger municipality is estimated at 210,794, ranking third out of New Cambria's 22 new municipalities in terms of population. Previously, Averytown ranked second out of New Cambria's 65 former municipalities, behind Arvant. Averytown was the only one of New Cambria's four largest municipalities to consolidate with another municipality.
