A continuous-state population-size-dependent branching process {X t } is a modification of the Jiřina process. We prove that such a process arises as the limit of a sequence of suitably scaled population-size-dependent branching processes with discrete states. The extinction problem for the population X t is discussed, and the limit distribution of X t / t obtained when X t tends to infinity.
