The Australian Bureau of Statistics (ABS) is wrapping up the formal collection period for the 2016 Census tomorrow.

The Census cand be quickly and easily completed online with the 12-digit login provided to some households.

Alternatively, householders who received the Census in paper form are encouraged to post it back in the provided reply-paid envelope.

Head of the 2016 Census Program, Duncan Young, said people can still contact the program if they have questions, and receive a paper form if they need one, once the online system has closed.

“Paper forms will continue to be accepted as they make their way back via return mail,” Mr Young said.

“Around 95 per cent of households have completed the Census,” he said.

“Census data influences federal funding to states, territories and local governments. Your participation is essential to the future of your community. Without this information, the government, organisations and community groups aren’t able to plan and provide vital services for you, your community and your area.

“Census data is used to inform decision and policy making in every area across Australia. It shows population growth and demographics to help plan investment in schools and day care facilities for children, aged care services for the elderly, hospitals and transport.

“Importantly, Census data shows how we are changing as a society and where we are heading so we can plan appropriately to support our future.”

The Census is compulsory for everyone who was in Australia on Tuesday, August 9, Census night.
