Background & Evolution
Post-2011 Reassessment
Following the 2011 census, significant concerns arose regarding the escalating costs and the continued relevance of the traditional decennial census methodology. The UK Statistics Authority initiated the "Beyond 2011 Programme" to explore alternatives, including more frequent, smaller-scale surveys and leveraging administrative data, prompted by technological advancements and evolving data needs.
The Digital Shift
A key recommendation from the Beyond 2011 Programme was a predominantly online approach for the 2021 census in England and Wales. This marked a significant departure from previous censuses, aiming for greater efficiency and data accuracy by encouraging online returns, supplemented by administrative and survey data. The target for online completion was set at a minimum of 65%.
Pandemic Impact
The censuses proceeded amidst the COVID-19 pandemic. While the England and Wales census took place as scheduled on 21 March 2021, the Scottish census was postponed to 20 March 2022 due to pandemic-related challenges. The pandemic underscored the importance of census data for understanding societal impacts and informing public policy.
Legislative Framework
Census Act 1920
The foundational legislation for census-taking in England and Wales remains the Census Act 1920. This act mandates participation and outlines the framework for census arrangements. Similar legislative procedures were required in Scotland and Northern Ireland, ensuring coherence across the UK.
Modern Amendments
Specific legislative amendments were introduced to accommodate new questions. The Census (Amendment) (Scotland) Act 2019 and the Census (Return Particulars and Removal of Penalties) Act 2019 enabled the voluntary inclusion of questions on sexual orientation and transgender status in Scotland, England, and Wales, reflecting evolving societal considerations.
Religion Question Dynamics
Advocacy for Accuracy
Campaigns, such as that by Humanists UK, advocated for clearer wording of the religion question to encourage accurate self-reporting by non-religious individuals. The aim was to provide a more precise reflection of religious adherence and non-adherence across the UK.
Climate Census Campaign
An unconventional campaign suggested writing "Climate concerned" in the religion section to draw attention to climate action demands. This highlights the evolving use of census forms as platforms for public expression and advocacy.
Sex vs. Gender Identity Debate
Legal Challenge
A legal challenge was mounted against the Office for National Statistics' guidance on the 'sex' question, specifically concerning gender self-identification. Campaign groups argued against allowing self-identification based on documents like passports, leading to a judicial review and a concession from the ONS, revising the guidance.
Academic Discourse
Academics engaged in debate regarding the ONS's approach, with some criticizing the conflation of sex and gender identity, while others supported the census design, citing the small size of the transgender population. The accuracy and interpretation of data related to gender identity later became a subject of scrutiny.
Scottish Context
In Scotland, similar guidance was issued, allowing transgender individuals to answer based on self-identification without a Gender Recognition Certificate. This faced scrutiny from the UK Statistics Authority and a legal challenge, which was ultimately dismissed by the Court of Session, affirming the guidance.
Coordinated Efforts
UK Statistics Authority Role
The UK Statistics Authority, through the Office for National Statistics (ONS), coordinated census activities across the United Kingdom. This central oversight ensured a degree of consistency in methodology and data collection, despite the distinct administrative responsibilities of devolved nations.
Agency Responsibilities
The ONS managed the census for England and Wales. The Northern Ireland Statistics and Research Agency (NISRA) handled the census in Northern Ireland, and National Records of Scotland (NRS) was responsible for Scotland's census.
Methodological Research
Optimizing Data Collection
Extensive research, initiated post-2011, focused on developing new census methodologies. This included trials for online data collection, assessing the utility and accuracy of administrative data sources, and exploring the potential for integrating survey data to provide more frequent population statistics.
Census Transformation
The Census Transformation Programme aimed to define the future shape of population statistics. Research strands were commissioned to determine the optimal blend of online census methods, administrative data, and traditional surveying techniques, with findings expected to inform censuses beyond 2021.
Project Work Programme
Eight Phases
The ONS developed an eight-phase work programme extending until 2024. Key phases included research (concluded March 2015), design and prototyping (concluded December 2016), testing (2017), development (2018), rehearsal (Jan 2019 - Jun 2020), collection operations (Jul 2020 - Dec 2021), analysis and dissemination (2022-23), and evaluation (2023-24).
Statistical Trials
Parallel to the main programme, trials were conducted from Autumn 2015 to 2021 to generate statistics using administrative data. These trials aimed to assess the breadth, detail, and accuracy of outputs achievable through alternative data sources.
Production & Contracts
Questionnaire Management
Leidos Innovations UK secured a contract valued at approximately £65.1 million for managing the preparation, dispatch of paper questionnaires, and digitization of responses. This followed Lockheed Martin UK's contract for the 2011 census.
Field Staff Recruitment
The Adecco Group UK & I was contracted by the ONS to recruit, train, and manage the payroll for the approximately 30,000 temporary field staff required for the 2021 census operations.
Key Changes from 2011
New Questions
The 2021 census introduced several new voluntary questions for individuals aged 16 and over, focusing on:
- Veteran status (ex-armed forces).
- Sexual orientation.
- Gender identity (asking if it differs from sex registered at birth).
Advertising Strategy
An advertising campaign, developed by M&C Saatchi under the slogan "It's about us," utilized television adverts featuring diverse individuals and a cover of The Zombies' "This Will Be Our Year." The campaign aimed to encourage participation and highlight the census's collective relevance.
Northern Ireland Census 2021
NISRA's Role
The Northern Ireland Statistics and Research Agency (NISRA) conducted the census on 21 March 2021. Pre-census publicity, unique internet codes (ePins), and coordinated promotional activities were identified as crucial elements based on international comparisons and previous census experiences.
Digital Focus
Similar to England and Wales, the Northern Ireland census heavily emphasized online completion, supported by Leidos Innovations UK. The census included the new voluntary questions on sexual orientation and gender identity.
Scotland Census 2022
Postponement and Turnout
Scheduled for March 2021, Scotland's census was postponed to March 2022 due to the COVID-19 pandemic. Despite an extended collection period and significant investment (£148m total), the census faced criticism for a record low return rate of 88%, falling short of the 94% target. This lower turnout has implications for data completeness.
Demographic Trends
Initial results indicated Scotland's population reached a record high of 5.44 million, though growth slowed compared to the previous decade. A significant trend observed was the aging population, with over 1 million people aged 65 and over, surpassing the number of children under 15. The proportion identifying with no religion increased substantially to 51.1%.
Crown Dependencies
Jersey & Isle of Man
Jersey conducted its census on the same day as the main UK censuses in 2021. The Isle of Man also held its full census in 2021, following an interim census in 2016.
Guernsey's Approach
Guernsey has moved away from decennial censuses, adopting a Rolling Electronic Census Project to generate regular population reports, reflecting a trend towards more continuous data collection.
Key Census Findings
England & Wales (2021)
The population reached 59.6 million, a 6.3% increase. Notably, the 65+ age group (11.1 million) now exceeds the under-15 population (10.4 million). Religious affiliation showed 46.2% identifying as Christian and 37.2% as having no religion. Sexual orientation data indicated 89.4% identified as straight/heterosexual.
Gender Identity Data Scrutiny
The census data on gender identity, particularly the 0.5% (262,000 individuals) identifying as transgender in England and Wales, faced scrutiny. Concerns were raised about potential overestimation due to misinterpretation of the question, especially among non-native English speakers and specific demographic groups. The Office for Statistics Regulation initiated an examination, and the accreditation of these statistics was later downgraded.
Scotland (2022)
Scotland's population reached 5.4 million. The census revealed an aging demographic, with over 1 million individuals aged 65+. The non-religious population grew significantly to 51.1%. Minority ethnic groups constituted 12.9% of the population, an increase from 8.2% in 2011.
