Help please

Hi ladies, I'm starting to do my senior final report for my Econ class so I'm doing my report on household salaries medians/ averages in the U.S and how it differs from each state. 
I just found out I'm pregnant so money has been On my mind. 
Please put in the comments below.
1. Household salary 
2. Family of ___  ( 1,2,3,4) 
3.  Is your income in the medium/ lower/high range
4. State 
I'd really appreciate the help since I can't find information that's up to date!
