The survey showed that of the 13 counties where people spent 13 percent or more of their family income on gasoline, 5 were located in Mississippi, 4 were in Alabama, 3 were in Kentucky and 1 was in West Virginia. While people here in Holmes County spent an average of 15.6 percent of their income on gasoline, people in Nassau County, N.Y., spent barely more than 2 percent, according to the survey.

Economists say that despite widespread concern about gasoline prices, the nationwide impact of the oil crisis has so far been gentler than during the oil crises of the 1970s and 1980s, when shortages caused long lines at the pump, set off inflation and drove the economy into recession.

Americans on average now spend about 4 percent of their after-tax income on transportation fuels, according to Brian A. Bethune, an economist at Global Insight, a forecasting firm. That compares with 4.5 percent in early 1981, the highest point since World War II. At its lowest point, in 1998, that share dropped to 1.9 percent.

“Gas prices have doubled over the last year but the economy has not fallen off the cliff,” said Rajeev Dhawan, director of the Economic Forecasting Center at Georgia State University. “But for the rural lower income people, as a proportion of their income the rise of gas prices is very high.”

While people everywhere are talking about gasoline prices these days, some folks in Tchula (the T is silent) have gone beyond talking.

Anthony Clark, a farm worker from Tchula, says he prays every night for lower gasoline prices. He recently decided not to fix his broken 1992 Chevrolet Astro van because he could not afford the fuel. Now he hires friends and family members to drive him around to buy food and medicine for his diabetic aunt, and his boss sends a van to pick him up for the 10-mile commute to work.
