ABSTRACT
For certain industries, particularly transport, distribution and finance, no regional figures exist, and an attempt to produce them would raise conceptual as well as practical difficulties. With ships and airlines, for instance, it would be difficult to decide how to apportion regional estimates even if sufficiently detailed figures could be obtained. The parts of the economy which are most adequately covered are those included in the Census of Production: manufacturing industry, mining and quarrying, and gas, electricity and water. The industries which were next in importance by amount of investment in Wales were chemicals and textiles: most probably this is accounted for mainly by oil refining and synthetic textiles. These industries also invested more as a proportion of net output in Wales than in Scotland or the United Kingdom as a whole. The Scottish gross investment ratios by industries are much closer to those of the United Kingdom, than were those of Wales.
