Gas prices have increased in New Jersey, but dipped across the nation as a whole, as lower demand compensated for a decrease in domestic stocks.

According to AAA Mid-Atlantic, the average price of a gallon of regular gas in the Garden State Friday was $2.23, up two cents from last week. Drivers were paying an average of $2.54 a gallon a year ago at this time.

The national average price for a gallon of regular gasoline was $2.18, down a penny from the previous week. Drivers were paying an average of $2.64 a gallon a year ago at this time.

Analysts say prices are likely to decline with a drop-in demand as fewer road trips are taken in the fall.
