Episode notes
Rising Childlessness Not Fewer Children Per Mother
- Birth decline is driven mainly by rising childlessness, not lower parity among mothers.
- In the UK mothers still average ~2.2 children but childlessness is rising toward one third due to delayed or failed attempts at parenthood.
Fertility Window Is Much Narrower Than People Think
- People lack knowledge of the narrow fertility window, which skews choices about delaying parenthood.
- Stephen J. Shaw finds the 50% chance of ever becoming a mother occurs at about age 28 in the UK and 26 in Japan, much younger than public perception.
Hollowed Suburbs Seen In Detroit And Japan
- Shrinking birth cohorts hollow out suburbs and collapse local services, as seen in Detroit and Japanese suburbs.
- Shaw recounts Detroit's decline and hollowed suburban communities in Japan where schools and services disappear.
