This article continues the series of annual estimates which started in the September 1963 Bulletin. It discusses the flow of funds between six sectors of the economy: persons, industrial and commercial companies, the public sector, the overseas sector, and financial institutions considered under two headings-banks (i.e., the banking sector) and other financial institutions. Definitions of sectors and of items in the tables, and notes on sources of the figures are given at the end of this article.
