We have collected various statistics from our database to show progress
in out postcode collection efforts.
Our main summary is below, as displayed on the main page:
</p>

<!--#include virtual="summary.html" -->

<p>
"Total postcodes collected" counts all postcodes collected on this site
that haven't been subseqently deleted, excluding those from our partner site,
<a href="http://freethepostcode.org/">freethepostcode.org</a>.
</p>

<p>
"Prefixes collected" lists the number of unique prefixes (also known as
"outwards" &mdash; the first half of a postcode collected, also excluding
freethepostcode.org data.
</p>

<p>
"Prefixes liberated" gives a rough percentage estimate of the number of
prefixes collected between both sites compared to the total in the country.
This is probably an over-estimate.
</p>

<p>
The <a href="missing_district_stats.html">Known missing prefixes</a>
page gives another measure of our progress, in terms of the prefixes/districts
we know about, collected from a separate source.
