What Is 2011 Census for England and Wales

Overview

The 2011 Census for England and Wales was a comprehensive national survey conducted to collect detailed demographic and socioeconomic data. It provided a statistical snapshot of the population on a specific day, forming a critical foundation for government planning and resource allocation.

Administered by the Office for National Statistics (ONS), the census occurs every 10 years, as required by law. The 2011 edition marked a significant shift toward digital data collection while maintaining traditional paper forms for accessibility.

• Population count: On 27 March 2011, the official population of England and Wales was recorded as 56,075,912, an increase of 3.7 million since the 2001 Census.
• Response rate: Over 95% of households returned their census forms, one of the highest compliance rates in the survey’s history, reflecting public trust in the process.
• Digital innovation: For the first time, households could complete the census online, with approximately 16% choosing this method, marking a shift toward modern data collection.
• Legal requirement: Participation was mandatory under the Census Act 1920, with non-compliance punishable by fines, ensuring near-universal coverage.
• Language diversity: The census identified over 180 languages spoken at home, highlighting the growing linguistic diversity across urban and rural communities.

How It Works

The 2011 Census followed a structured, legally enforced process to ensure accurate and comprehensive data collection across all regions of England and Wales.

• Enumeration: The process of counting every resident on census day. Enumerators visited non-responding households to ensure complete coverage and minimize undercounting.
• Census day: Set as 27 March 2011, this fixed reference point ensured all data reflected the same moment in time for consistency.
• Household questionnaire: Each household received a form with 50+ questions covering age, sex, ethnicity, employment, housing, and health status.
• Anonymization: Personal data was stripped of identifiers after processing; only anonymized statistics were published to protect privacy under the Data Protection Act.
• Field operations: Over 30,000 temporary staff were hired to distribute forms, follow up non-respondents, and assist vulnerable populations.
• Data coding: Responses were digitized and coded using standardized classifications, such as the National Statistics Socioeconomic Classification, for analysis.

Comparison at a Glance

Comparing the 2011 Census with previous decades reveals key demographic shifts in population size, diversity, and household composition.

Why It Matters
