Bloomberg News ranked artists based on the average secondary-market prices for concert tour tickets for shows from Memorial Day to Labor Day 2013 in the U.S. and Canada.
The most popular tours were selected based on searches on secondary-market ticket price aggregator TiqIQ. Average secondary-market prices were determined by totaling the value of all tickets available on the secondary market according to TiqIQ and dividing by the number of tickets available on TiqIQ as of June 10. Figures are list prices. List prices are volatile and typically change closer to concert dates.
