Background: To determine the rates of birth registration over a five-year period in New South Wales (NSW) and explore the factors associated with the rate of registration. %26lt;br%26gt;Methods: This is a cross-sectional study using linked population databases. The study population included all births of NSW residents in NSW between 2001 and 2005. %26lt;br%26gt;Results: Birth registration rates in NSW were 82.66% in the year of birth, 93.19% in the first year, 94.02% in the second, 94.56% in the third and 95.08% in the fourth year after birth. The non-registration of births was mainly associated with such factors as neonatal and postneonatal death (adjusted OR = 3.84, 95% CI: 3.23-4.57); being Indigenous (adjusted OR = 3.26, 95% CI: 3.10-3.43); maternal age %26lt;25 or %26gt;39 years (adjusted OR = 2.81, 95% CI: 2.72-2.90); low birthweight (%26lt;2,500 grams) (adjusted OR = 1.79, 95% CI: 1.69-1.90); living in remote areas (adjusted OR = 1.57, 95% CI: 1.52-1.63); being born after the first quarter of year (adjusted OR = 1.08-1.56, 95% CI between 1.03-1.12 and 1.49-1.64); mother having more pregnancies (adjusted OR = 1.85-7.29, 95% CI between 1.78-1.93 and 6.87-7.73). Mothers who were born overseas were more likely to register their births than those born in Australia (adjusted OR = 0.72, 95% CI: 0.69-0.75). Multiple births were more likely to be registered than singleton births (adjusted OR = 0.84, 95% CI: 0.76-0.92). About one-third of the non-registrations of births in NSW were explained by the risk factors. The reasons for the remaining non-registrations need to be investigated. %26lt;br%26gt;Conclusion: Of birth in NSW, 4.92% were not registered by the fourth year after birth.
