This report on the Flow of Intra-Commonwealth Aid for 1970 is the fifth in a series giving a comprehensive statement of official aid flows within the Commonwealth. From the beginning of this series of reports on the flow of official aid, data have been collected and compiled on a programme basis in order to make available aggregate information for individual programmes, such as the Special Commonwealth African Assistance Plan. This information is not elsewhere available on a Commonwealth basis as the Colombo Plan is the only programme for which an annual report is prepared.
