PIATTI Observatorio Astronomico, Universidad Nacional de Cordoba, Laprida 854,5000 Cordoba, Argentina; piatti@uncbob.edu.ar Received 1995 February 6; accepted 1995 June 29 ABSTRACT We present a catalog of integrated UBV photometry of 504 star clusters and 120 stellar associations in the LMC, part of them still embedded in emitting gas. We study age groups in terms of equivalent SWB types derived from the (U-B) X (B-V) diagram. The size of the spatial distributions increases steadily with age (SWB types), whereas a difference of axial ratio exists between the groups younger than 30 Myr and those older, which implies a nearly face-on orientation for the former and a tilt of ~45^deg^ for the latter groups. Asymmetries are present in the spatial distributions, which, together with the noncoincidence of the centroids for different age groups, suggest that the LMC disk was severely perturbed in the past.
