The Authority may send by post a household pack to such households in the address register, and an individual pack to such electors in the address register, as the Authority considers necessary for the purpose of the census in advance of census day.

If the Authority does not send a household pack or an individual pack by post under paragraph (1) it must instead require the relevant census co-ordinator to arrange delivery by hand of a household pack or an individual pack to that household or elector (as the case may be) in accordance with regulation 10.

In respect of each census pack sent by post in accordance with paragraph (1), the Authority must ensure that a record is made in the questionnaire tracking system to show the address to which the census pack was sent.
