According to the 1835 census the parish had a population of 2,921 shortly before it became a municipality.[4] On 1 January 1861 the town of Gjøvik (population: 626) was separated from Vardal to constitute a separate municipality, leaving Vardal with a population of 4,114. On 1 January 1896, a small area of Østre Toten Municipality (population: 49) was transferred into Vardal. On 1 January 1900, an unpopulated area of Søndre Land Municipality was transferred to Vardal.[5]
