Here are the 10 least affordable countries for gas or gasoline when measured against average national incomes. The U.S. consumes more gasoline than any other country, and the average household spends about $2,000 a year on gas. But in the last few years, low gas prices have given millions of drivers extra money to spend or save.

In the rest of the world, gas prices tend to be higher. But the nominal price of gasoline doesn’t provide a complete picture of how expensive the fuel really is in a given country. In order to determine the affordability of gasoline (or any other product), you have to compare the price to income. A recent Bloomberg report compared gas prices in different countries to the average national paycheck to find where gas really is the most, and least, affordable.

In high-wage nations, expensive gas prices are by and large affordable for the population. For example, Norway’s gasoline price of $6.53 a gallon is the third highest in the world, but its average citizen earns nearly $200 a day. This combination means that Norway’s high prices are the 10th most affordable in the world. On the other end of the spectrum, Nigeria, Africa’s leading oil producer, boasts the 7th cheapest gas prices in the world at $1.94 a gallon. But when coupled with an $8 average daily wage, Nigeria’s gas becomes the 4thleast affordable in the world.
