The gravitational density wave theory of Lin et al. (1964, 1969) is used to trace the evolution of spiral galaxies to determine the locations of star systems with ages close to our own, which may have civilizations near the same level of development. Stars are projected to have formed within a concentrated shock front corotating in the spiral structure. Locations of star systems diverge from circular paths due to the spiral pattern, with the diffusion of stars governed by the pattern velocity and the galactic rotation velocity. The angular distance of a star cluster from a spiral arm is an indicator of the cluster age. Stars in the solar neighborhood, or in similar positions in other inter-arm regions, would therefore be closest to the sun in age. The similarly-aged stars are calculated to lie on a 3 kpc corotation region with the sun. It is recommended that SETI scans be concentrated on the corotating star systems.
