Charting the Dramatic Gas Price Rise of the Last Decade

Different Situation, But Prices Are Not Unprecedented

In a previous column, I pointed out that — perhaps surprisingly — the price we’ve been paying for gas lately, compared to 90 years ago, is not as high as people would think — that is, once the rate of inflation is factored in to the equation.  For instance, while motorists may have been paying only $0.25/gallon in 1919, when converting that number to February 2012 dollars, the cost was $3.35/gallon — a mere 6.5 percent cheaper than 2011′s annual average of $3.57/gallon. The chart below shows the price movement (based on February 2012 dollars) from 1919-2011.

How High Have Gas Prices Risen Over the Years?

Inflation Adjusted Data

Gas prices are spiraling through the roof like never seen before. People often point to specific years that gas was so cheap, in an effort to blame politicians, Big Oil, or whomever else is the flavor of the day. Indeed, a gallon of gas was going for only a quarter of a dollar in the years after World War I, and even less than that before and after World War II.

A 1920 Standing Liberty Quarter could buy you more than a gallon of gas for most of the years after World War I until after World War II.

But the key fact that’s missing from all the ranting and raving is the rate of inflation. The simple definition of inflation according to Wikipedia is: “A rise in the general level of prices of goods and services in an economy over a period of time.” Keep in mind, that at the end of World War I, average annual income was only $1,500. Currently, annual income is around $50,000.

For this exercise I plotted various sets of data in graphs — sometimes combined — based on information compiled by the U.S. Department of Energy’s (DOE) statistical office, the Energy Information Administration (EIA). The purpose of this two-part segment is to provide a clearer understanding of how much the price of gas has actually gone up relative to a family’s budget and other household costs, and most importantly, during what time frame.
