15"Total postcodes collected" counts all postcodes collected on this site
16that haven't been subseqently deleted, excluding those from our partner site,
17<a href="http://freethepostcode.org/">freethepostcode.org</a>.
18</p>

21"Prefixes collected" lists the number of unique prefixes (also known as
[435]22"outwards" &mdash; the first half of a postcode collected), also excluding
[349]23freethepostcode.org data.
24</p>

26<p>
27"Prefixes liberated" gives a rough percentage estimate of the number of
28prefixes collected between both sites compared to the total in the country.
29This is probably an over-estimate.

31
32<p>
[435]33"Sectors collected" lists the number of unique sectors (places with the
34same "outward" part, and the same first number of their "inward" part,
35such as "OX11 4AB" and "OX11 4TZ"), excluding freethepostcode.org data.

39"Sectors liberated" gives a rough percentage estimate of the number of
40sectors collected between both sites compared to the total in the country.
41This is probably an over-estimate. (The total number for the country is
42taken from
43<a href="http://www.graticule.com/products/PostcodeFocus.html">here</a>.)

[349]47The <a href="missing_district_stats.html">Known missing prefixes</a>
48page gives another measure of our progress, in terms of the prefixes/districts
49we know about, collected from a separate source.
