Notes

Census Day was the 21st of March 2021. The ONS perturbs every count slightly to protect privacy, each cell on its own, so a council's categories can add up to a total a few people different from one topic to another, and its councils add up to England's and Wales's counts only within a few dozen.
By council as the ONS's Census API gives them, its lower-tier local authorities of 2023, with Barnsley's and Sheffield's figures under the codes they had until the 1st of April 2025, as the API gives them. Scotland's and Northern Ireland's censuses are separate, so their councils are not here.
Every council's categories together count all its households.
The ONS's description of the topic, “Occupancy rating for rooms (6 categories)”: Whether a household's accommodation is overcrowded, ideally occupied or under-occupied. This is calculated by comparing the number of rooms the household requires to the number of available rooms. The number of rooms the household requires uses a formula which states that: * one-person households require three rooms comprised of two common rooms and one bedroom * two-or-more person households require a minimum of two common rooms and a bedroom for each of the following: 1. married or cohabiting couple 2. single parent 3. person aged 16 years and over 4. pair of same-sex persons aged 10 to 15 years 5. person aged 10 to 15 years paired with a person under 10 years of the same sex 6. pair of children aged 10 years, regardless of their sex 7. person aged under 16 years who cannot share a bedroom with someone in 4, 5 or 6 above An occupancy rating of: * -1 or less implies that a household’s accommodation has fewer rooms than required (overcrowded) * +1 or more implies that a household’s accommodation has more rooms than required (under-occupied) * 0 suggests that a household’s accommodation has an ideal number of rooms The number of rooms is taken from Valuation Office Agency (VOA) administrative data for the first time in 2021. The number of rooms is recorded at the address level, whilst the 2011 Census recorded the number of rooms at the household level. This means that for households that live in a shared dwelling, the available number of rooms are counted for the whole dwelling in VOA, and not each individual household. VOA’s definition of a room does not include bathrooms, toilets, halls or landings, kitchens, conservatories or utility rooms. All other rooms, for example, living rooms, studies, bedrooms, separate dining rooms and rooms that can only be used for storage are included. Please note that the 2011 Census question included kitchens, conservatories and utility rooms while excluding rooms that can only be used for storage. To adjust for the definitional difference, the number of rooms required is deducted from the actual number of rooms it has available, and then 1 is added.
The ONS's quality statement: It is inappropriate to measure change in number of rooms from 2011 to 2021, as Census 2021 used Valuation Office Agency data for this variable. Instead use Census 2021 estimates for number of bedrooms for comparisons over time.
