    What about small populations? For example, your sample size of 385 makes no sense for a small population of 100. Can you direct me to a source that would explain this?

    Frankly, your post makes no sense either.  It seems to be out of context and possibly a reply to another thread.  As to what I think you are saying probably refers to the Finite Population Correction Factor.  Do a web search on it to get specifics.  At a high level, the usual sample size calculations assume a large population.  Where a small population exists, some adjustment is needed to reflect that.  That is where the correction factor comes in.
