Every household in Jersey will receive a census form over the next fortnight ahead of Census Day on 21 March.
We're all legally required to complete the questionnaire once a decade.
This year marks 200 years since the first ever census was taken.
Head of Statistics Sarah Davis explains why it's something that we all need to take part in:
"It gives us a snapshot at a point in time, not just of how many people live in Jersey - but also the structure of our population, so by age, gender, place of birth, how many people are employed and so on. Everybody needs to take part. This information is vital for government to be able to plan what services like school places, hospital beds, health services and infrastructure are needed within the island."
This year's census will include questions on health and disability, and voluntary questions on sexuality and gender identity said to be important for monitoring progress against equalities legislation and providing data that is not currently available.
Jersey’s population according to the 2011 census was 97,857 compared with 28,600 at the first census in 1821.
For the first time in Jersey, Islanders can choose to complete the census online using a unique code to access form.
The results of the census will be published in early 2022.
Islanders who fail to complete the census are liable to a fine of £1,000.
