Purple light in Middlesbrough to show a reminder of Census Day 2021

Buildings and landmarks across Middlesbrough are being bathed in purple to mark a once-in-a-decade event.

The striking light show is a colourful reminder that this Sunday, March 21 is Census Day - and taking part is a legal requirement.

The aim is to provide an accurate snapshot of all the people and households in England and Wales and, with the exception of 1941, censuses have taken place every ten years since 1801.

This year's census will be the first to be carried out predominantly online, with the questionnaire able to be completed using a computer, mobile phone or tablet.

The survey - which takes around ten minutes - covers a range of questions about sex, age, work, health, education, household size, and ethnicity.

For the first time, people will be asked if they have served in the Armed Forces, as well as voluntary questions for those aged 16 and over about sexual orientation and gender identity.

Middlesbrough Mayor Andy Preston said:

"The census isn't just compulsory - it's really important, and I'd urge everyone who's received the letter go get online on Sunday and fill it in.

"The results of the census are used to inform how councils are funded, so the more accurate the picture we have, the more chance we have of getting a fair deal.

"It's also a vital source of data that will help to shape local decision-making for things like affordable housing and schools, not just now but for generations to come."

Iain Bell, deputy national statistician at the Office for National Statistics, said:

"A successful census will ensure everyone from local government to charities can put services and funding in the places where they are most needed.

"This could mean things like doctors' surgeries, schools and new transport routes.

"That's why it is so important everyone takes part and we have made it easier for people to do so online on any device, with help and paper questionnaires for those that need them."
