Administration as the closest proxy for the core historic environment sector. <strong>The</strong> output multiplier for the<br />

Public Administration sector, as presented in the Irish input-output tables, is estimated at 1.51 66 . A similar<br />

estimate is not available for employment and GVA multipliers and we have therefore used an<br />

approximation based on the multipliers developed for the Public Administration sector in Scotland 67 . In<br />

summary:<br />

GVA multiplier = 1.69, calculated as [Output multiplier in Ireland (1.51)/ Output multiplier in Scotland (1.7)]<br />

multiplied by GVA multiplier in Scotland (1.9)<br />

Employment multiplier = 1.60, calculated as [Output multiplier in Ireland (1.51)/ Output multiplier in<br />

Scotland (1.7)] multiplied by employment multiplier in Scotland (1.8)<br />

<strong>The</strong>se derived multipliers may then be applied to the values for direct effects to produce estimates <strong>of</strong> total<br />

economic impact for the 'Inner Wheel' <strong>of</strong> <strong>Ireland's</strong> historic environment sector.<br />

Built <strong>Heritage</strong> Construction Sector<br />

<strong>Economic</strong> activity corresponding to those components <strong>of</strong> the construction sector which relate specifically<br />

to <strong>Ireland's</strong> built heritage does not fit neatly into traditional economic disaggregations or standard industry<br />

classifications. Consequently, there is a lack <strong>of</strong> directly observable values concerning the size and<br />

importance <strong>of</strong> the sector in terms <strong>of</strong> employment and output. In order to overcome these data<br />

deficiencies we have used published data on total construction output in Ireland together with best<br />

supporting evidence and reasoned assumptions to apportion that share <strong>of</strong> output which may be attributed<br />

to the built heritage sector as a basis for deriving robust estimates <strong>of</strong> the sector's value.<br />

Based on publically available data contained in the Construction Industry Review and Outlook (CIRO), it<br />

is estimated that approximately €5.8 billion <strong>of</strong> the total Irish construction industry output (€18 billion)<br />

corresponds to elements associated with repair, maintenance and improvement (RM&I) (2009 figures).<br />

In order to provide a measure <strong>of</strong> the share <strong>of</strong> this RM&I output which may be attributed specifically to the<br />

built heritage construction sector, we have made reference to: (1) the pr<strong>of</strong>ile characteristics <strong>of</strong> <strong>Ireland's</strong><br />

residential building stock and, (2) the overall value <strong>of</strong> residential RM&I output nationally. According to<br />
