<p>Our community has 3 custom closure options (self-study, either not stats or about software, data set requests), plus two immutable closure options (migration, other/leave a comment).</p>
<p>Users with more than 10k rep can view how often the closure reasons are used during the previous 90 days via this query: <a href="https://stats.stackexchange.com/tools/question-close-stats?daterange=last90days">https://stats.stackexchange.com/tools/question-close-stats?daterange=last90days</a></p>
<p>The &quot;data sets&quot; option is the least-used option. Even the option which prompts the user to write a comment is used more often than the &quot;data sets&quot; option.</p>
<p>Please note that adding an additional closure reason is not an option available to us at this time. <a href="https://stats.meta.stackexchange.com/a/5606/22311">A previous effort to add a fourth custom closure reason was declined.</a> Moreover, in explaining why it was declined, Catija (an SE representative) explained that the relative disuse of the &quot;data set requests&quot; was a part of the reason.</p>
<p>Removing a vote-to-close reason doesn't change what's on- or off-topic on this site, it just changes the menu options when a person opens the VTC dialogue. A user can still select &quot;this is not about statistics as described in the [help],&quot; or  they could select &quot;other - add comment&quot; and paste the text of the current &quot;data set request&quot; option. The menu of options is just a matter of convenience, so that reviewers have ready-made closure reasons for the most common varieties of off-topic questions.</p>
<p>Since the &quot;data set request&quot; option is so rarely used, should we retire it? Doing so would free a slot for a custom option which could be more useful.</p>
