"As we discussed on the phone, the official poverty measure for the nation comes from Current Population Survey (CPS-ASEC).
And it is recommended to use the American Community Survey (ACS) to get income and poverty rate estimates for state and lower-level geographies.
If you have any question, please let us know. Thank You."
