Salzburg has slipped a point since the January 13 ratings, put together by Around The Rings, in part due to the fallout from the Walter Mayer affair in Turin.
Out of 110 points in the Power Index, Salzburg scores 80.
Sochi picks up 10 points over the January poll with 74, but is still in third place in an increasingly tight race.
Second place goes to PyeongChang at 76, up one from January. Almaty rises to fourth, followed by Jaca, Sofia, and Borjomi.
The index is the third edition from Around the Rings since the campaign for 2014 began in July 2005.
The 11-category index covers a range of technical points as well as more subjective areas, such as the ambience of a city or the last time an Olympics were held in the city or nation.
