The information is provided in table 1 as follows.

All numbers which appear in national tables have been rounded to the nearest 100 if they exceed 1,000 and to the nearest 10 otherwise. Numbers from 1 to 5 inclusive have been suppressed, being replaced in the table by a hyphen (-). It has been necessary to suppress other figures whenever it would be possible to calculate the value of a suppressed number by a means of simple arithmetic. The rule applied in these circumstances has been to suppress the next smallest data item provided its value is strictly less than 20.
