HUD provide data for the median income at the 30%, 50% 80% percentile of median income, by FIPS Code for household sizes 1 thru 8.

See http://www.huduser.org/portal/datasets/il/il14/index.html

Some sample data

STATE:ARIZONA ---------------------------I N C O M E L I M I T S---------------------------- PROGRAM 1 PERSON 2 PERSON 3 PERSON 4 PERSON 5 PERSON 6 PERSON 7 PERSON 8 PERSON Flagstaff, AZ MSA FY 2014 MFI: 57900 EXTR LOW INCOME 12500 15730 19790 23850 27910 31970 36030 39300 VERY LOW INCOME 20850 23800 26800 29750 32150 34550 36900 39300 LOW-INCOME 33350 38100 42850 47600 51450 55250 59050 62850

I'm looking for data or an 'approved' method to get the 100% median income for household sizes 1 thru for each FIPS code.

As Andrew has suggested, you could just use ACS data here. Make sure to download as a .csv to get the FIPS State-County codes.


You won't find 100% median income in the tables because HUD qualification is limited to low and very low income families and individuals.


The income data comes from the US Census and American Community Survey.

You can calculate it yourself. Just do 2X the 50% value. Note that HUD rounds the results to the nearest $250 increment.
