 x: \nDescription: I study “Malthusian Flocks”: moving aggregates of se
 lf-propelled entities (e.g.\, organisms\, cytoskeletal actin\, microtubule
 s in mitotic spindles) that reproduce and die. Long-ranged order (i.e.\, t
 he existence of a non-zero average velocity) is possible in these systems\
 , even in spatial dimension d=2. Their spatiotemporal scaling structure ca
 n be determined exactly in d=2\; furthermore\, they lack both the longitud
 inal sound waves and the giant number fluctuations found in immortal flock
 s. Number fluctuations are very persistent\, and propagate along the direc
 tion of flock motion\, but at a different speed.
