Rauma Group is the largest company in Ørskog in terms of turnover.

At the time if its dissolution in 2020, the 132 km2 municipality was the 363rd largest by area out of the 422 municipalities in Norway. Ørskog is the 309th most populous municipality in Norway with a population of 2,267. The municipality's population density is 17.6 PD/km2 and its population has increased by 7% over the last decade.

Ørskog was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). On 1 August 1883, the southwestern district of Ørskog (most of Ørskog on the southwestern side of the Storfjorden except for the Søvik and Ramstaddalen areas) was separated to form the new Søkelven Municipality. This left Ørskog with 1,735 inhabitants. On 1 June 1955, the Søvik and Ramstaddalen areas of Ørskog (south of the Storfjorden) were administratively transferred to Sykkylven Municipality. On 1 January 1965, Skodje Municipality (to the west) and Stordal Municipality (to the south) were merged into Ørskog to form a new, larger Ørskog Municipality. This merger was not long-lived. On 1 January 1977, the three municipalities were separated again.

On 1 January 2020, the municipality of Ørskog was merged with Haram Municipality, Skodje Municipality, Sandøy Municipality, and Ålesund Municipality to form one large municipality of Ålesund.
