Everyone expects the statistician to be the foe of easy generalization and glib phrases. Hardheadedness and a sceptical approach are occupational characteristics of those who spend their days measuring the world objectively. In talking to you about statistics of the balance of payments I am therefore going to stay on firm ground by discussing several recent developments in Canada's balance of payments and in the statistical tools which have been devised for observing them.

Balance of payments developments have close interrelationships with the internal economy, which, I feel, have never been satisfactorily elucidated. For those interested in studying them further there are two new statistical sources which will facilitate closer analysis. These are new reports soon to be published by the Dominion Bureau of Statistics showing quarterly statements of the national accounts and quarterly statements of the balance of payments in the post-war period. Quarterly statistics of this kind are comparatively new tools and consequently must be used with care, particularly when relationships between internal and external factors are being explored. A thorough knowledge of concepts, definitions, and sources is indispensable before even the obvious steps in comparison may be taken with confidence. Knowledge must also be acquired of the seasonal behaviour of the various series entering into these statistics, in order to distinguish the special and non-recurring from the seasonal. Frequent data on the monetary background published by the Bank of Canada also throw new light on related transactions.
