Abstract: Considering the fuzziness and randomness, which are two kinds of uncertain factors in the population system, it is obtained that a class of stochastic fuzzy age-structured population equations with diffusion and Poisson jumps. Such equations can be useful in modeling of hybrid dynamic systems. Under the coefficients of the equation satisfying Lipschitz condition together with boundedness condition(which is weaker than linear growth condition), it can apply the method of successive approximation by constructing Picard iteration sequence to discuss the existence and uniqueness of solutions to stochastic fuzzy age-structured population equations with diffusion and Poisson jumps. Using Gronwall lemma、 fuzzy stochastic It\hat\mathrmo integral and triangle inequality, the sufficient condition for the existence of the strong solution is given and an estimation of error of approximate solution is established.
