A (general) branching process, where individuals need not reproduce
independently, satisfies a homogeneous growth condition if, vaguely, one would
not expect the progeny from any one individual to make out more than its proper
fraction of the whole population at any time in the future. This notion is made
precise, and it is shown how it entails classical Malthusian growth in
supercritical cases, in particular for population size-dependent
Bienaymé-Galton-Watson and Markov branching processes, and for
nondecreasing age-dependent processes with continuous life span
distributions.
