The 2001 "One Number Census" project

The "One Number Census" project aims to integrate the population counts from the 2001 census with estimated levels of underenumeration, derived from the census coverage survey (see www.statistics.gov.uk/nsbase/census2001/pdfs/oncguide.pdf).

"For the 2001 Census, the Office for National Statistics, and the statistical agencies of Scotland and Northern Ireland implemented ambitious and innovative plans to maximise response and to minimise the variation in response between different types of people. Through a very large interview survey of 300,000 households after the census, the number and characteristics of non-respondents were estimated, the census database was expanded to include records representing non-respondents, and census output represents an estimate of the full population. This is the One Number Census (ONC)" (Simpson L, Hobcraft J, King D. The 2001 one number census and its quality assurance, 2003. www.lga.gov.uk/Documents/Publication/onenumbercensus.pdf).
