You won't find any Census info about him because the 1940 Census is the latest available to the public.
You can try to order a copy of his birth certificate from the Arizona Department of Health Services, azdhs.gov/vitalrcd/birth_index.htm . I say try because Arizona restricts access to birth records, however, since you're an adult child they might make an exemption. It's all explained at the above web site.
Even though the Social Security Death Index says his Last Residence was Compton, Los Angeles Co., CA that might not be true. He could have died in another town or city.
An obituary might have been published for him. Since Compton is the only info we have, let's search there. That's part of the Los Angeles County Library System, www.colapublib.org/contactus/
and they do search for obituaries. Successful Searching!
