There's one implementation in www.yoursite.com/admin/statistics/overview

You can find the code for the page from the file views/default/admin/statistics/overview/numentities.php

Thanks I've had a look and clearly need to learn how to combine code and I have my <?php and headers all mixed up with html.

This is the code from the numentities.php

<?php
// Get entity statistics
$entity_stats = get_entity_statistics();
$even_odd = "";
?>        
<table class="elgg-table-alt">
<?php



foreach ($entity_stats as $k => $entry) {
    arsort($entry);
    foreach ($entry as $a => $b) {

        //This function controls the alternating class
        $even_odd = ( 'odd' != $even_odd ) ? 'odd' : 'even';

        if ($a == "__base__") {
            $a = elgg_echo("item:{$k}");
            if (empty($a))
                $a = $k;
        } else {
            if (empty($a)) {
                $a = elgg_echo("item:{$k}");
            } else {
                $a = elgg_echo("item:{$k}:{$a}");
            }

            if (empty($a)) {
                $a = "$k $a";
            }
        }
        
        echo <<< END
            <tr class="{$even_odd}">
                <td>{$a}:</td>
                <td>{$b}</td>
            </tr>
END;
        }
    }
?>
</table>

Just dont know how to embed in a page.

I recommend going through the tutorials to learn the basics: http://docs.elgg.org/wiki/Tutorials
