<p>The BBC produce statistics relating to evasion rates in the UK using a model that compares the number of licences in force to external statistics on the number of households and other licensable places in the UK.</p><p>In order to give an estimated figure by nation, the BBC use a calculation referred to as “crude evasion”. The crude evasion rate is calculated using a process which estimates the number of unlicensed sites as a percentage of the “licensable universe”, where the licensable universe is the total number of sites, adjusted by an</p><p>estimate of those that are unoccupied on the TV licensing database. Using this crude evasion calculation gives a figure of 8.10% for Northern Ireland for 2012-13.</p>
