> Can someone please explain to me what a one-number census is?
see text below - this is an extract (page 2) from the the Office for
National Statistics (ONS) publication "A Guide to the One Number Census",
available on-line from:
http://www.statistics.gov.uk/census2001/pdfs/oncguide.pdf
What is a One Number Census?
1.1 The One Number Census (ONC) project aims to integrate the 2001 Census
counts
with the estimated level of underenumeration in the Census – that is the
number of
households and people not counted. First it will provide a new base for the
mid-year
population estimates at the Local Authority District (LAD) level, and second
it will
adjust the Census database itself for the estimated undercount so that all
statistics add
to ‘One Number’ - the national estimate of the population.
1.2 The primary source in estimating the underenumeration will be the
Census Coverage
Survey (CCS). This has a notably different design to the Census Validation
Survey
undertaken following the 1991 Census.
1.3 The project derives its name from the intention to eliminate
different population
counts so that all census outputs add to one number - the national
population estimate
which has been adjusted for underenumeration. Furthermore the mid-year
population
estimates will be based on these ONC population estimates and there
will be
transparency between them.
1.4 The ONC Project considered the methodology separately for England
and Wales,
Scotland and Northern Ireland. The high-level methodology presented here
is
consistent throughout the UK. Although there are some differences, these are
mainly
associated with the design and practical aspects of the Census Coverage
Survey and
the use of different geographies during the quality assurance process in
Scotland.
