Geographies Or boundary data available on Nottingham Insight
Geographies • A number of different boundaries are available on Nottingham Insight. • This presentation will explain the different boundaries and how they sit together.
Objectives • Explain the key boundaries • Explain how the different boundaries nestle together • Which boundaries are specific to Nottingham City • Explain larger geographies available through to the smaller level geographies • Explain how data on Insight is aggregated to different geographies
Key Boundaries • The three main boundaries used on Nottingham Insight are District, Ward and Super Output Areas.
Key geographies Ward LSOA District
District Level • In Nottinghamshire there are 7 districts:- • Ashfield • Bassetlaw • Broxtowe • Gedling • Mansfield • Newark & Sherwood • Nottingham City • Rushcliffe
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.
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 Middle Super Output Areas
