asked the Chancellor of the Exchequer, from information available from international sources, what was the gross domestic product per head at factor cost in Canada for the most recent year for which information is available; and how this compares with the figure for the same year for the United Kingdom.

The latest year for which information is available is 1975. Details are as follows:

GROSS DOMESTIC PRODUCT(1) PER HEAD OF TOTAL POPULATION
		US dollars
Canada	…	6,994
United Kingdom	…	4,065
(1) In purchasers' values

Estimates based on purchasing power parities are not available for Canada.
