• Explain how the different boundaries nestle
together
• Which boundaries are specific to Nottingham
City

to the smaller level geographies

Wards
• Wards vary considerably in population size from
1,600 to 21,400 people with an average size of 5,700
people.
• If you are looking to use wards as standard
comparable areas, precaution should be used.
Wards
• Wards are represented at local authority level
by councillors, and the availability of statistical
information for wards has considerable
importance for local government.
Wards
• On Nottingham Insight, all Census data is
displayed using the 2011 wards.
• It is worth noting that Newark and Sherwood,
Bassetlaw and Mansfield have changed their
ward boundaries since the 2001 Census.
• Datasets for these wards are provided on a
best fit for the ward.
Wards
• There are 192
wards within
Nottinghamshire
• Within the City of
Nottingham, there are
20 wards.
Output Areas
• Output Areas were designed for the 2001 Census to
enable data to be released for small, comparable
areas below ward level.
• A small number of revisions were made in 2011 to
take into account changes in the population and to
ensure they remained of comparable size.
• There are 3,609 Output Areas in Nottinghamshire
with an average of 128 households per area.
Output Areas
• Output Areas are mostly used to produce
Census data for small areas.
• Other data is generally released for larger
areas to maintain confidentiality.
• Output Areas provide the ‘building blocks’ for
creating these larger areas.
Lower Super Output Areas
• Super Output Areas are
made up from groups of
Output Areas and are
generally the smallest
area for which data is
available
• There are 679 Lower
Super Output Areas in
Nottinghamshire. (Average
1,500 households)
Lower Super Output Areas
• They provide a basis for comparison
throughout the country because the areas
have similar numbers of households.
• There are 32,844 Super Output Areas in
England and 679 in Nottinghamshire, of which
182 are within the City of Nottingham.
Middle Super Output Areas
• These boundaries were created from the 2001
census and contain similar numbers of households.
• The 138 Middle Super Output Areas have an average
of 3,300 households each.
• They are built from groups of Lower Super Output
Areas
Middle Super Output Areas
• Middle Super Output Areas are not widely
used as they are generally of a similar size to
wards.
• They are mainly used when releasing data for
a smaller area would risk the confidentiality of
the data, or when larger areas of comparable
size are needed.
Middle Super Output Areas
• On Nottingham Insight a number of datasets are
available at MSOA.
• For example:• Births and deaths
• Disability living allowance claimants
• Country of birth
• Pupil absences
Nottingham City Boundaries
• The following boundaries are specific to
Nottingham City and are included on
Nottingham Insight.
Area Committees
• Specific to Nottingham
City.
• Eight Area Committees
covering the whole City
each comprising two or
three adjoining wards.
• Area Committees enable
ward councillors, along
with local residents and
other stakeholders, to
influence what happens in
each area either through
direct decision making or
consultation.

Nottingham City
