Blackville was first incorporated as a village in 1967, annexing the neighbouring communities of Underhill and Breadalbane later that year.
On January 1, 2023, Blackville amalgamated with all or part of eight local service districts to form the new incorporated rural community of Miramichi River Valley.
[5] Blackville residents are able to cast votes in the Miramichi River Valley Rural Community's elections for mayor, three at-large councillors, and the Ward 3 councillor.
A large sawmill that employed 200 workers had been operated in the village by industrial conglomerate UPM Kymmene, but it closed in 2007 as a result of economic pressures.
According to the 2016 Census, Blackville citizens had a median income of $30,816 for individuals, and $62,976 for households in 2015.
