Birth and death registrations in Hong Kong are governed by the Births and Deaths Registration Ordinance. Parents must report the birth of their child in Hong Kong to the Registrar of Births and Deaths within 42 days and the birth can be registered without any fee. A fee is charged if the birth is registered after 42 days and not later than one year. Registration beyond 12 months after the birth of the child requires the consent of the registrar. During the year, 51 births were post-registered. There are four district birth registries providing birth registration service to the public.

Deaths from natural causes should be registered by relatives within 24 hours. Hong Kong has three death registries providing free service, and death may also be registered at one of the 15 designated police stations in the New Territories and outlying islands.

During the year, 57 124 live births and 38 683 deaths were registered, as compared with 48 914 and 37 322 respectively in 2004.
