Human population renewal starts with births. Since births can happen at any time in the year and over a wide range of ages, demographers typically imagine the birth series as a continuous ﬂow. Taking this construct literally, we visualize the Swedish birth series as a ﬂow. A long birth series allows us to juxtapose the children born in a particular year with the children that they in turn had over the course of their lives, yielding a crude notion of cohort replacement. Macro patterns in generational growth deﬁne the meandering path of the ﬂow, while temporal booms and busts echo through the ﬂow with the regularity of a pulse.
