[jQuery] Counting Lists inside of Lists

[Tim]

So I have a main list of states in an unordered list and then a
unordered list of cities within each of those. So I wanted to count
the number of cities per state.
<ul class="state_list">
<li>
        <h2>Alabama</h2>
        <ul>
            <li><a href="http://www.google.com";>Alabama State</a></li>
            <li><a href="http://www.google.com";>Alabama State</a></li>
            <li><a href="http://www.google.com";>Alabama State</a></li>
            <li><a href="http://www.google.com";>Alabama State</a></li>
        </ul>
</li>
</ul>

$('.state_list > li').each(function(i){
                $(this+ '> li').count();
        });

It will let me put anything inside of the each function except for
counting or length, when I do that it blows up the whole site without
any errors..
