GEOG 245 Lecture Notes - Lecture 9: Inflection Point, Population Momentum, Social Capital
Document Summary
Drop until 1975, subsequent increases & drops, etc. Population momentum: even if overall fertility decreases, number of births may stay high (echo boom) In good times, people don"t tend to limit their fertility as in bad times (on a societal level) On the local level: there is much variation: corresponds to things like snowstorms. If we don"t have access to power, fertility increases. Consider the pill: released in 70s; graph roughly equal around that time. More people pursuing higher education (profound impact on women) In 1980s, 25-29 age group surpasses 20-24 age group. Normative sequencing (finish education/get a job before starting family) Some give birth young, some delay until later. Some geographic variation: much of middle us is light purple as opposed to green. Life circumstances differ: those invested in social capital (higher education) usually have children later (takes time) Considerable variation, but today, trending the same way downward. Normative sequence shift: coupling having children marrying.
