Every ten years the Office for National Statistics (ONS) is responsible for undertaking a census or population count. A census took place on Sunday, 27 March 2011, when each household was asked to complete a form (online or on paper) listing all people present at the time.
The statistical information collected determines what government funding the borough receives in the following years to deliver key public services like education, healthcare, housing, social services and transport. Personal information collected is protected by law and kept strictly confidential.
You can find out more on the census 2011 website.
