Agriculture remains the dominant industry in the provincial economy, as it has since colonial times. During the 20th century, potatoes replaced mixed farming as the leading cash crop, accounting for one-third of provincial farm income. The province currently accounts for a third of Canada’s total potato production, producing approximately 1.3 billion kilograms annually. Comparatively, the state of Idaho produces approximately 6.2 billion kilograms annually, with a population approximately 9.5 times greater. The province is a major producer of seed potatoes, exporting to more than twenty countries around the world.
