  In this paper we present a thorough study on the existence of traveling waves
in a mathematical model of dispersal in a partially sedentary age-structured
population. This type of model was first proposed by Veit and Lewis in [{\it
Am. Nat.}, {\bf 148} (1996), 255-274]. We choose the fecundity function to be
the Beverton-Holt type function. We extend the theory of traveling waves in the
population genetics model of Weinberger in [{\it SIAM J. Math. Anal.}, {\bf 13}
(1982), 353-396] to the case when migration depends on age groups and a
fraction of the population does not migrate.
