We investigate a state estimation problem for an infinite dimensional system appearing inpopulation dynamics. More precisely, given a linear model for age-structured populations with spatialdiffusion, we assume the initial distribution to be unknown and that we have at our disposal anobservation locally distributed in both age and space. Using Luenberger observers, we solve the inverseproblem of recovering asymptotically in time the distribution of population. The observer is designedusing a finite dimensional stabilizing output injection operator, yielding an effective reconstructionmethod. Numerical experiments are provided showing the feasibility of the proposed reconstructionmethod.
