Interested in measuring the spread between the median and mean household income in New York County (aka Manhattan) going back to 1990. Where can I get median and mean household income at the county level going back 20 years?

Sources I've found:

Here is median income for NY State for that time period: http://www.statista.com/statistics/205974/median-household-income-in-new-york/

ACS has this info, but only back to ~2009: https://factfinder.census.gov/faces/tableservices/jsf/pages/productview.xhtml?pid=ACS_14_5YR_S1901&prodType=table

Estimate-based data for mean and median household income at the county level is available for: 1990, 2000, 2005-2009, 2006-2010, 2007-2011, 2008-2012, 2009-2013, 2010-2014 ( and 2011-2015 in Dec. 2016). American Factfinder is a good resource for these estimates. NHGIS is a good resource for processed Census data that is GIS-friendly.

Model-based data for median household income at the county level is available through SAIPE.
