In general, the study of society is called sociology. There isn't a specific name for studying how society stays the same, particularly since our recent experience has been that societies do not stay the same. However, there are mechanisms that are intended to protect an existing social structure, so to that extent, there are at least attempts to keep society the same. External factors tend to force change on society, even when it is an internally stable society.
