After thinking about it a bit more, the only reasonable conclusion I can come to is the following:<p>It&#x27;s the number of times users actually typed<p><pre><code>    bower install lodash
</code></pre>
i.e. adding it to a project that didn&#x27;t already have it, as opposed to just running bower install on a package which uses lodash.<p>Would also explain why despite bower itself being installed 37000 times in the last 7 days, the most installed package is only listed as 100 or so times.
