This note investigates the extension of Roberts' price-independent welfare prescriptions to alternatives in which population size and composition can vary. We show that ethically unsatisfactory orderings result. Suppose that a single person is to be added to a population that is unaffected in utility terms. Either all such additions must be regarded as bad or some expansions in which the added person's life is not worth living must be ranked as social improvements.
