The Total Fertility Rate (cont.)

Period table with cohort example

The table below shows age-specific fertility rates for seven calendar periods.  The TFR for the first three periods have been calculated and you are asked to calculate TFRs for the remaining periods.

These are the “normal” period TFRs.  Could we calculate a cohort TFR?  Yes we can, but only in a limited way.  This is dealt with on the next page.
