<p>The Help Center has a page for <a href="https://stats.stackexchange.com/help/on-topic">What topics can I ask about here?</a>. Part of it states:</p>

<blockquote>
  <p>Questions about <strong>obtaining particular datasets</strong> are off-topic (they are too specialized). The <a href="https://gis.stackexchange.com/">GIS site</a> welcomes inquiries about obtaining geographically related datasets.</p>
</blockquote>

<p>It seems strange to link to the GIS site but not to <a href="https://opendata.stackexchange.com/">Open Data</a>, which exists specifically for this purpose.</p>

<p>I appreciate Open Data is only in beta, but recent SE announcements make clear no beta site is in imminent danger of being culled.</p>

<p>Similarly, quite a few requests that get closed here are for economic data, and these requests seem to be considered on-topic on <a href="https://economics.stackexchange.com/">Economics SE</a>, as can be seen from their <a href="https://economics.stackexchange.com/questions/tagged/data-request">data request tag</a>. If GIS is linked from our on-topic help, I think it might be worth including Economics too. Perhaps something like this?</p>

<blockquote>
  <p>Questions about <strong>obtaining particular datasets</strong> are off-topic (they are too specialized). The <a href="https://opendata.stackexchange.com/">Open Data site</a> is suitable for general requests for publicly available data. The <a href="https://gis.stackexchange.com/">GIS site</a> and <a href="https://economics.stackexchange.com/">Economics site</a> welcome inquiries about obtaining geographic and economic datasets respectively.</p>
