Wikipedia:RfA inflation

RfA inflation is the belief that as time goes on, the standards for an RfA candidate rise. It is a result of a statistical approach to candidate analysis, with the statistics needed gradually rising with time. The most obvious dangers being that of an overall decline in successful RfA, leading to a decline in active administrators. Problems will result if there are an inadequate number of active admins to do the tasks that require their toolset.
