Digest of Welsh Historical Statistics : Coal, 1780-1975

This machine-readable version of John Williams' &lt;i&gt;Digest of Welsh Historical Statistics&lt;/i&gt; is the result of a collaboration between the Statistical Directorate of the National Assembly for Wales, the History Data Service and the Centre for Data Digitisation and Analysis at Queen's University Belfast.<br>John Williams' &lt;i&gt;Digest of Welsh Historical Statistics&lt;/i&gt; is intended to provide a service for those working on the history of modern Wales. It arises from a belief that the quantitative element is a necessary and important part of the historical record; from an awareness that it was an aspect that was particularly inaccessible for scholars of Welsh history; and from a conviction that some encouragement in the use of quantitative material was necessary. It is modelled on the two volumes dedicated to British historical statistics: Mitchell, B.R. and Deane, P. (1962) &lt;i&gt;Abstract of British historical statistics&lt;/i&gt; and Mitchell, B.R. and Jones, H.G. (1971) &lt;i&gt;Second abstract of British historical statistics&lt;/i&gt;.
