If analysts need any early signals that the drop in oil prices has begun to affect gasoline prices, it is the fall off in the cost of an average gallon of regular across the 50 states. Gas prices are below $3.50 in 11 of them.

The price of an average gallon of regular nationwide is $3.64 according to GasBuddy, and it has not changed substantially for weeks. Before that, as the crises in the Middle East worsened, gas prices rose as crude reached nearly $110. Since then, it has fallen back to slightly more than $103, and it is still falling.

Oil prices do not play the only role in the price of gasoline. The U.S. Energy Information Administration (EIA) reports gas prices could rise in the second half if geopolitical threats, particularly in Iraq, worsen. For the time being, that assessment is too aggressive.

Among the other factors in gas prices are refinery capacity and prices, and the cost of transportation. Among the most visible evidence of this is that most states with low gas prices are near refineries or a large energy producers. Many of the states on the low price gas list are clustered around the Gulf of Mexico, close to some of the largest refineries in the United States. Seven of the 10 largest U.S. refineries are in Texas and Louisiana. Gas prices are very low in these states, which include Alabama (with an average price of $3.38), Mississippi ($3.40), Oklahoma ($3.43), Louisiana ($3.44), Texas ($3.47), Arkansas ($3.42), Kansas ($3.49), Missouri ($3.46) and Tennessee ($3.42).

Two other states with low gas prices are South Carolina ($3.34) and Virginia ($3.46).

There will always be a debate about at what level high gas prices become a major drag on American gross domestic product. A month ago, they were likely to have been a threat. Lower- and middle-class households based on income continue to face pressure as real income has not risen in a decade. Food, shelter and clothing make up too much of their budgets to allow for large increases in energy costs. This is particularly true for households where some residents have to drive many miles per year.

For the meantime, the economy seems set for some relief as gas prices have started to drop. More and more states are likely to have gas prices at “affordable” levels.
