Each year's increase or decrease in the trade deficit (merchandise imports greater than exports) is calculated in relation to the previous year's. In 1976, imports of private vehicles were 10 percent higher than in 1975, while imports of vehicles including commercial vans was 15 percent higher than in 1975. That 15 percent increase was one and a half times the increase recorded in 1975.
