Abstract: In part 1 we identified a coupling between death spikes and birth dips that occurs following catastrophic events such as influenza pandemics and earthquakes. Here we seek to characterize some of the key features of this effect. We introduce a transfer function defined as the amplitude of the birth trough (the output) divided by the amplitude of the death spike (the input). It has two salient features: (i) it is always smaller than one so is an attenuation factor and (ii) as a function of the amplitude of the death spike, it is a power law with exponent close to unity.
