The considerable public discussion of the past two years on the subject of our social insurance schemes and their post-war reconstruction has culminated in the publication of the Government's plans as a White Paper (Cmd. 6550–1). At present, social insurance in this country (now to be called National Insurance) is divided into a number of independent sections, each with its own statistical arrangements covering a large part of the population. At the same time some aspects of the whole population are regularly surveyed by the Registrars-General by means of an independent system of recording. The Government's plan greatly expands the field of insurance to cover all classes and groups. Before this unified plan can begin to function, fresh statistical machinery will have to be prepared, adequate to the task of keeping it efficiently in operation, and there will in consequence be a great opportunity for coordinating, simplifying and generally improving the national population records as a whole.
