A lookup between 2011 Census enumeration postcodes for England and Wales, and the parishes / communities, wards and local authority districts as at 31 December 2011. Enumeration postcodes are a sub-Output Area (OA) geography used only for the publication of estimates of males, females and households in the 2011 Census. The enumeration postcodes are defined as only those valid unit postcodes that were recorded during the 2011 Census as containing usually resident population. Postcodes have been assigned using a ‘point-in-polygon’ methodology that plots each postcode's mean address (centroid) into the areas of each of the parishes / communities, wards and local authority districts (LAD). In England there is not a full coverage of parishes, so the 2011 Census enumeration postcodes that do not fall into a parish will have no parish allocation. There are also 23 parishes (0.2%) that do not contain any enumeration postcode centroids. This occurs where a parish contains population, but the centroid of the postcode falls outside the parish. In these instances it is not possible to allocate a postcode to the parish.

This is the ONS Postcode Directory (ONSPD) for the United Kingdom as at February 2023 in Comma Separated Variable (CSV) and ASCII text (TXT) formats. This file contains the multi CSVs so that postcode areas can be opened in MS Excel. To download the zip file click the Download button. The ONSPD relates both current and terminated postcodes in the United Kingdom to a range of current statutory administrative, electoral, health and other area geographies. It also links postcodes to pre-2002 health areas, 1991 Census enumeration districts for England and Wales, 2001 Census Output Areas (OA) and Super Output Areas (SOA) for England and Wales, 2001 Census OAs and SOAs for Northern Ireland and 2001 Census OAs and Data Zones (DZ) for Scotland. It now contains 2021 Census OAs and SOAs for England and Wales. It helps support the production of area based statistics from postcoded data. The ONSPD is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The ONSPD is issued quarterly. (File size - 234 MB)NOTE: The 2022 ONSPDs included an incorrect update of the ITL field with two LA changes in Northamptonshire. This error has been corrected from the February 2023 ONSPD.NOTE: There was an issue with the originally published file where some change orders yet to be included in OS Boundary-LineÔ (including The Cumbria (Structural Changes) Order 2022, The North Yorkshire (Structural Changes) Order 2022 and The Somerset (Structural Changes) Order 2022) were mistakenly implemented for terminated postcodes. Version 2 corrects this, so that ward codes E05014171–E05014393 are not yet included. Please note that this product contains Royal Mail, Gridlink, LPS (Northern Ireland), Ordnance Survey and ONS Intellectual Property Rights.

Data History Data Origin These samples were taken from customer taps. They were then analysed for water quality, and the results were uploaded to a database. This dataset is an extract from this database. Data Triage ConsiderationsGranularity We decided to share as individual results as the lowest level of granularity.Anonymisation It is a requirement that this data cannot be used to identify a singular person or household. We discussed many options for aggregating the data to a specific geography to ensure this requirement is met. The following geographical aggregations were discussed:Water Supply Zone (WSZ) - Limits interoperability with other datasets.Postcode – Some postcodes contain very few households and may not offer necessary anonymisation.Postal Sector – Deemed not granular enough in highly populated areas.Rounded Co-ordinates – Not a recognised standard and may cause overlapping areas.MSOA – Deemed not granular enough.LSOA – Agreed as a recognised standard appropriate for England and Wales.Data Zones – Agreed as a recognised standard appropriate for Scotland.Preferred: Geospatial to LSOA.Why is Geospatial to LSOA preferred? It is more accurate since the postcode mapping is best fitted by plotting the location of the postcode's mean address rather than sample point’s specific location.Data Specifications Each dataset will cover a calendar year of samples:This dataset will be published monthly.Historical datasets will be published as far back as 2022 following the introduction of the Water Supply Regulations. https://www.legislation.gov.uk/uksi/2016/614/contents/made The Determinands included in the dataset are as per the list that is required to be reported to the Drinking Water Inspectorate.ContextMany UK water companies provide a search tool on their websites where you can search for water quality in your area by postcode. The results of the search may identify the water supply zone that supplies the postcode searched. Water supply zones are not linked to LSOAs which means the results may differ to this dataset.Some sample results are influenced by internal plumbing and may not be representative of drinking water quality in the wider area. In this case these test results are omitted from the dataset.Some samples are tested on site and others are sent to scientific laboratories.Data Publish FrequencyMonthly.Data Triage Review FrequencyAnnually unless otherwise requestedSupplementary information Below is a curated selection of links for additional reading, which provide a deeper understanding of this dataset.Drinking Water Inspectorate Standards and Regulations: https://www.dwi.gov.uk/drinking-water-standards-and-regulations/ LSOA (England and Wales) and Data Zone (Scotland): https://www.nrscotland.gov.uk/files/geography/2011-census/geography-bckground-info-comparison-of-thresholds.pdf  Description for LSOA boundaries by the ONS: Census 2021 geographies - Office for National Statistics (ons.gov.uk) Postcode to LSOA lookup tables:  Postcode to 2021 Census Output Area to Lower Layer Super Output Area to Middle Layer Super Output Area to Local Authority District (August 2023) Lookup in the UK (statistics.gov.uk) Legislation history: Legislation - Drinking Water Inspectorate (dwi.gov.uk) Dataset SchemaSAMPLE_ID: Identity of the sampleSAMPLE_DATE: The date the sample was takenDETERMINAND: The determinand being measured DWI_CODE: The corresponding DWI code for the determinand UNITS: The expression of resultsOPERATOR: The measurement operator for limit of detection RESULT: The test resultsLSOA or DATA ZONE: Lower Super Output Area or Data Zone (population weighted centroids used by the ONS (Office for National Statistics) for geo-anonymisation)

Data containing the Output Areas and Output Areas to higher geographies within Glasgow City Council based on the 2011 Census aggregates. It shows a output area codes for Glasgow and a lookup of postcode to output area, data zone, intermediate geography, electoral ward code and other higher geographies with their corresponding Easting and Northing. Output Areas are the main building bricks for census areas. They are derived from aggregating a small number of neighbouring postcodes although in few cases, some postcodes are large enough to become single output areas. Output Areas will aggregate exactly to council areas but not necessarily to other higher geographies. Glasgow City Council Area Code used in the 2011 census is S12000046.

Referential lookup of GP practices and their respective M code for use with Fingertips data at GP level for the Birmingham and Solihull Integrated Care Board (ICB).Data has been enriched with LSOA, MSOA, Ward, Constituency, Longitude, Latitude and map point.This list should not be used for any purpose other than working with Fingertips powered data.

The LSOA atlas provides a summary of demographic and related data for each Lower Super Output Area in Greater London. The average population of an LSOA in London in 2010 was 1,722 compared with 8,346 for an MSOA and 13,078 for a ward. The profiles are designed to provide an overview of the population in these small areas by combining a range of data on the population, diversity, households, health, housing, crime, benefits, land use, deprivation, schools, and employment. Due to significant population change in some areas, not all 2011 LSOA boundaries are the same as previous LSOA boundaries that had been used from 2001. A lot of data is still only available using the 2001 boundaries therefore two Atlases have been created - one using the current LSOA boundaries (2011) and one using the previous boundaries (2001). If you need to find an LSOA and you know the postcode of the area, the ONS NESS search page has a tool for this. The LSOA Atlas is available as an XLS as well as being presented using InstantAtlas mapping software. This is a useful tool for displaying a large amount of data for numerous geographies, in one place (requires HTML 5). CURRENT LSOA BOUNDARIES (2011) NOTE: There is comparatively less data for the new boundaries compared with the old boundaries PREVIOUS LSOA BOUNDARIES (2001) For 2011 Census data used in the 2001 Boundaries Atlas: For simplicity, where two or more areas have been merged, the figures for these areas have been divided by the number of LSOAs that used to make that area up. Therefore, these data are not official ONS statisitcs, but presented here as indicative to display trends. NB. It is currently not possible to export the map as a picture due to a software issue with the Google Maps background. We advise you to print screen to copy an image to the clipboard. IMPORTANT: Due to the large amount of data and areas, the LSOA Atlas may take up to a minute to fully load. Once loaded, the report will work more efficiently by using the filter tool and selecting one borough at a time. Displaying every LSOA in London will slow down the data reload. Tips: - Select a new indicator from the Data box on the left. Select the theme, then indicator and then year to show the data. - To view data just for one borough, use the filter tool. - The legend settings can be altered by clicking on the pencil icon next to the LSOA tick box within the map legend. - The areas can be ranked in order by clicking at the top of the indicator column of the data table.
