The problems of the spatial and velocity distributions of planetary nebulae in our galaxy are still very much with us. In what follows we comment rather hastily on the older work and more especially on the recent work in these fields. We have not been able to carry out an exhaustive literature search, and therefore trust we shall be forgiven by those whose contributions do not appear herein. We first survey the scene in the greater solar neighborhood. Section 2 deals with the local spatial distribution of planetaries in the galactic plane and perpendicular to the plane. Section 3 focuses on the rather meager results that can be obtained on the kinematical properties of the planetaries in our general part of the galactic system. We conclude by moving farther afield and exploring another part of the galaxy and the galaxy as a whole. Section 4 addresses the distribution of planetaries and summarizes recent estimates of the total planetary population of our galaxy. Finally, Section 5 is devoted to what little one can conclude about the overall kinematical properties of the system of planetaries.
