Defining "Socioeconomic Spectrum"?

Question

I just recently read "Nickel and Dimed" by Barbara Ehrenreich and in the book she briefly describes herself returning to her place on socioeconomic spectrum. I tried doing a search to find out more about what a socioeconomic spectrum really is but I did not really find any websites with more information, and I could not find it on wikipedia either. So I was wondering, is anyone able define the words "socioeconomic spectrum"?

:)thanks.
