Caracas, Venezuela topped the list after runaway inflation hurdled the city from 32nd place to 1st in one year. Surveyors found price levels 40% above the second costliest city: Oslo, Norway. Luanda, Angola came in third partly due to import tariffs that have hiked the price for a half-liter tub of vanilla ice cream to $31. Rounding out the list was Juba, South Sudan, where a 90 kilometer drive along one of the only continuous roads to the outside world can take upwards of 24 hours to navigate, according to the World Bank.
