Default Population estimating

I am sure this as probably been discussed on Net54 before, but is there any reliable method anyone knows of on how to estimate the population existing of various cards from the 1930's through the 1950's? For instance, what was the estimated original issuance / production figure for each set or card, and how many would we estimate have survived, etc. I suspect perhaps there is a formula for taking the population reports from PSA and SGC and any other major grading companies, adding them up and multiplying by 10 or 20 or something like that. Any thoughts?
