<p>You can use the <a href="http://data.stackexchange.com/stats/queries" rel="nofollow">Data Explorer</a> for this. The data is updated fairly regularly. (It's supposed to be monthly, but as of the posting of this answer, the last update was on June 27, 2012.)</p>

<p><a href="http://data.stackexchange.com/stats/query/81275" rel="nofollow">Here</a> is an example query I made for you, which you could modify to your liking.</p>

<pre><code>select * from Users
where Location like '%Ireland%'
order by reputation desc
</code></pre>

<p>This, of course, only shows users that actually provide a location in their profiles and it may not be accurate since it is self-reported and not authenticated.</p>
