Compare your income to other Americans and see where you fit in.
And you might be interested in who is middle class:
Who is a middle-income American? For much of the nation, the answer
is simple: it’s me, and perhaps people who earn less than I do.
"The latest Wall Street Journal/NBC News poll,
released Friday, showed the overwhelming majority of the public — 90% —
defining a “middle-income household” as families with total income at or
below $100,000. Americans have a strong inclination to consider people in their own income brackets to be middle-income."
"The findings suggest Americans may have a narrower definition of
middle-income households than many politicians do. Some lawmakers often
put the cut-off closer to $200,000 or $250,000 (in many cases using the
looser term “middle class”), leading them to look out closely for
taxpayers who earn more than what the rest of the nation might consider
to be middle-income." Details at: http://blogs.wsj.com/economics/2013/09/13/how-do-you-define-middle-class-people-who-make-what-i-do/
