Document Summary
Definition: # of births / mid-period population * 1000. What are problems with this measure: total fertility rate (tfr): A summary measure of age-specific fertility rates. Difference between period tfr and cohort tfr. Definition: the level of tfr at which women, on the average, have enough daughters to replace themselves in the population. Always above 2 (at least one son born for every daughter, some potential mothers die) Has already occurred in europe and most other mdcs, as well as some ldcs (like china), still on-going in other countries (esp. countries in sub-saharan africa) European fertility decline: variation in starting dates and pace of decline. France earliest, ireland latest: most of the declines started between 1890 and 1920, use of parish records to reconstruct demographic history, two components: Declining childbearing of married couples (from natural fertility to parity-specific control) Is their fertility as high as is biologically possible: parity-specific control.
