APPENDIX A.

would certainly have been much smaller in the Manchester Unity Experience,
 it would necessarily have as its consequence more linking-up, and
therefore more short attacks paid at the disablement rate. In the
nature of the case this feature would be of less importance at
ages over 40 than at the younger ages. The experience at ages over 40
appears, in fact, to confirm the corresponding experience in respect of
sickness benefit.
7. The average duration of disablement claims within the year is shown,
in weeks, by Table 3.

8. The average duration within the year is, of course, substantially less
than the total duration of disablement benefit, since cases of prolonged
disablement may extend over several years. In consequence the differeaces
in average duration of claim in the two experiences are somewhat masked
in the figures shown above.
By making certain assumptions it is possible to calculate approximately
the average total duration of disablement claims, and the resulting figures
are shown, in weeks, in Table 4 below.

9. As might be anticipated the figures confirm those of Table 8, and
emphasise the striking differences between the Manchester Unity Experience
 and that of the Selected Societies.
