XXXII. STATEMENT SHOWING WHAT PER CENT., OR WHAT NUMBER
IN 100, IS EQUAL TO 1 IN A GIVEN NUMBER; AND IN WHAT
NUMBER IS EQUAL TO A GIVEN PER CENT., OR A GIVEN NUMBER
IN 100.

This table is read thus. Suppose we wish to know what is the per
centage of births, marriages or deaths, when either is 1 in 81 of the
population. Look at 1 in 81 at the top of the central column, and it is
found to be 1.234 per cent. Or, if the known per centage be 2.439,
as in the next left-hand column, it is found to be 1 in 41.
