      <abstract xml:lang="en">&lt;P&gt;Abstract copyright UK Data Service and data collection copyright owner.&lt;/P&gt;This machine-readable version of John Williams' &amp;lt;i&amp;gt;Digest of Welsh Historical Statistics&amp;lt;/i&amp;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.&lt;br&gt; John Williams' &amp;lt;i&amp;gt;Digest of Welsh Historical Statistics&amp;lt;/i&amp;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) &amp;lt;i&amp;gt;Abstract of British historical statistics&amp;lt;/i&amp;gt; and Mitchell, B.R. and Jones, H.G. (1971) &amp;lt;i&amp;gt;Second abstract of British historical statistics&amp;lt;/i&amp;gt;.</abstract><abstract xml:lang="en">&lt;B&gt;Main Topics&lt;/B&gt;:&lt;BR&gt; The main tables are:&lt;br&gt; &lt;br&gt;</abstract><abstract xml:lang="en">Output and number of collieries, North Wales and South Wales, 1854-1874&lt;br&gt; Output.
