Teaching Kimchi has another nice table comparing ESL salaries and whatnot from a collection of countries:
Country Monthly Salary (USD) Insurance Flight Housing Severance Dubai $3,200-5,000 No Yearly Return Airfare Free and Furnished No Taiwan $3,000-4,000 Depends on program No Free not furnished No Korea $2,000-2,300 Depends on your salary Roundtrip Furnished Apt. One month salary after contract Japan $2,000 Depends on program Roundtrip Depends on program Extended holidays Thailand $800-1,000 Depends on program Roundtrip Depends on program Depends on school Russia $900 No Roundtrip Free and furnished No China $400-550 No Depends on length Free and furnished One month salary Vietnam $370 Depends Depends on length Free local food No
One thing that is lacking is adjustments for the cost of living. For example, the cost of eating in Dubai is $450 US per month but in Taiwan it's around $140 US (NT$150 x 30 days) and in Korea it's around $270 per month.
