Correction to: Chapter 4 in: N. Botev, The Sexuality-Reproduction Nexus and the Three Demographic Transitions, SpringerBriefs in Population Studies, https://doi.org/10.1007/978-3-030-37555-3_4

The original version of the book was inadvertently published with an incorrect equation in Chapter 4. The affected chapter has been updated with the changes and the correct presentation is given here.

$$ R_{0} = e^{rT} \qquad\qquad \text{or} \qquad\qquad T = \frac{ln\,R_{0}}{r} $$
