<p>The <a href="https://stats.stackexchange.com/questions/tagged/bivariate" class="post-tag" title="show questions tagged &#39;bivariate&#39;" rel="tag">bivariate</a> tag is a <a href="http://mathworld.wolfram.com/ProperSubset.html" rel="nofollow noreferrer">proper subset</a> of <a href="https://stats.stackexchange.com/questions/tagged/joint-distribution" class="post-tag" title="show questions tagged &#39;joint-distribution&#39;" rel="tag">joint-distribution</a>. </p>

<p>I have updated wiki excerpts as follows:</p>

<blockquote>
  <p>Joint probability distribution of several random variables gives the probability that all of them simultaneously lie in a particular region.</p>
</blockquote>

<p>and</p>

<blockquote>
  <p>Joint probability distribution of two variables.</p>
</blockquote>

<p>Briefly looking at the questions, it seems that most questions in the <code>[joint-distribution]</code> are actually about bivariate distributions, even though many of them are not tagged with <code>[bivariate]</code>. Given that, we could consider mapping <a href="https://stats.stackexchange.com/questions/tagged/bivariate" class="post-tag" title="show questions tagged &#39;bivariate&#39;" rel="tag">bivariate</a>$\to$<a href="https://stats.stackexchange.com/questions/tagged/joint-distribution" class="post-tag" title="show questions tagged &#39;joint-distribution&#39;" rel="tag">joint-distribution</a>. I do not have strong feelings about this. What do people think?</p>
