The initial population of Steinkjer was 1,150. On 1 January 1964, a major municipal merger took place, as the municipalities of Beitstad, Egge, Kvam, Ogndal, Sparbu, and Stod were all merged with the town of Steinkjer (population: 4,325) to form a new, larger municipality of Steinkjer. Both the European Road E6 and the Nordland Line run through the town, the latter serving the city at Steinkjer Station.
