There is a line in the study material which is as follows:
it is possible to work with the age and cohort but the cohort approach makes heavy data demands and there is a largely insolvable problem that the recent cohort have their history truncated by the present day.
firstly what is this unsoluble problem and what does it means by their " recent history truncated by the present day "
Thanks
