We are committed to ensuring we deliver a high quality, inclusive census and a lot of work has gone into making sure we had all the right addresses to send access codes or questionnaires, minimising burden as much as possible by making it simple to complete and working closely with community groups to promote Census 2021 and iran rcs data encourage people to respond. giving help and encouragement to those who have not yet filled in their census questionnaire online or on paper after Census Day and direct them to the support services they need. They will be operating in the same way as a postal or food delivery visit, will never need to enter people’s homes, they will always be socially distanced, equipped with PPE and work in line with all government guidance.
In 2011 we achieved a response rate of 94%. We know there will always be people who don’t fill in the census and we need a way to account for this non-response/under coverage in our estimates. As in 2011, we’ll run a Census Coverage Survey (CCS) shortly after the Census and we’ll use this to estimate the total population. More information on how we do this (Dual System Estimation) is available on the ONS website and will feature in an upcoming UKDS Impact blog as part of this series.
