“…With regard to the first question, the fertility rebound (despite being more moderate in magnitude) has already exceeded the baby boom, in terms of its length, in many countries. Furthermore, for several demographic researchers, it is projected as a persistent characteristic in the demographic trends of many developed countries for the foreseeable future (e.g., Alkema et al ., 2011; Collins and Richards, 2013; Schmertmann et al ., 2014). These are the reasons why, rather than being a temporary (cyclical) change, the fertility rebound reflects a more persistent change in trend, whereas the consensus of the literature on the theory of fertility is that the baby boom was a temporary interruption to the secular decline in fertility rates that began during the late 1800s (e.g., Van Bavel and Reher 2013).…”
