Salaries by region of online community

In a recent study done by the Online Community Report, they took a look at the compensation for those working with online community members. I found these two facts to be particularly interesting:

' The highest average / median annual salary in the USA comes from the research participants located in the northwest region. The average salary for the northwest region was $90k with a median of $90k.
' The lowest average / median annual salary in the USA comes from the research participants located in the southeast region. The average salary for the southeast region was $72k and the median was only $67k.
