CITY HHINCOME for 2008-2012 for San Diego and San Jose California

Hello, the PolicyLink National Equity Atlas has calculated Income Inequality 20/95 for larger cities across the nation including San Diego and San Jose, California, using IPUMS 2008-2012 (example:,_CA/United_States/Year(s):2012/).

I want to calculate a similar metric (income inequality 20/80) but I can’t find data for San Diego or San Jose for the 2008-2012 ACS sample.

Could you indicate how I can find these data?

Thank you.
