[2] In 1977, the city and county governments consolidated to form the single entity of Butte-Silver Bow.

[citation needed] As of the 2010 census, there were 34,200 people, 14,932 households, and 8,651 families living in the county.

In terms of ancestry, 32.6% were Irish, 23.3% were German, 16.1% were English, 8.3% were Italian, 6.9% were Norwegian, and 3.2% were American.

Since 1977, Butte and Silver Bow County have been consolidated into one governmental body under the leadership of the chief executive and the council of commissioners.

Elected in November 2020, J.P. Gallagher is the incumbent Chief Executive of Butte-Silver Bow, a nonpartisan office.

In 2024, Donald Trump, though still losing the county, became the first Republican to get within ten percent of carrying it since the aforementioned 1956 election.

Over the last century, Silver Bow County has voted only once for a Republican gubernatorial candidate (Marc Racicot during the 1996 election).
