Mid-year (30 June) estimates of the usual resident population for Lower layer Super Output Areas (LSOAs) in England and Wales by broad age groups and sex.

This dataset has been converted from a download of geography data from the Office for National Statistics Neighbourhood Statistics website. It provides information about Lower layer Super Output Areas (LSOAs), their location and the Local Authority District to which they belong. Where a LSOA intersects with a parish, the dataset includes a link from LSOA to parish. Because LSOA and parish boundaries do not align, it is possible for an LSOA to intersect with several parishes. Note that parishes only exist in some parts of England, therefore there are many LSOAs with no link to a parish. The data is currently available from http://opendatacommunities.org/data/lower-layer-super-output-areas/

This dataset provides population estimates for the lower layer super output areas (LSOAs), middle layer super output areas (MSOAs), upper layer super output areas (USOAs) and local authorities in Wales. These estimates are consistent with the results of the 2011 Census and are available for the 2011 LSOA, MSOA and USOA geographic boundaries published in October 2012. Super output areas (SOAs) were introduced in 2004 to improve the reporting of small area statistics. They are built from groups of census output areas, are of a consistent size and are not subject to boundary changes between censuses. Where possible they are formed from groups of socially similar households and align with local features such as roads and railway lines. The comparability and stability of the geography is a key benefit to users of statistics which cannot be provided by other small area administrative geographies such as wards or parishes. Following the 2011 Census, some boundary changes to SOAs were required and the new set of SOA boundaries was published in October 2012, although the stability of the geography has been largely maintained. Three hierarchical levels of SOAs are available in Wales. LSOAs were designed to have a population of between 1,000 and 3,000 in 2011, and there are 1,909 of them in Wales. MSOAs were designed as aggregations of LSOAs, had a population of between 5,000 and 15,000 in 2011, and there are 410 of them in Wales. USOAs are aggregations of MSOAs and were defined in conjunction with local authorities in Wales. There are 94 of them in Wales and they are only defined in Wales. This data does not differ from that published in the separate table (POPU1015), but it is presented using a different hierarchy to allow the user to more easily select the data from a single layer of the geography (for example, selecting only the lower super output areas, without the other area types). Further information on SOAs, can be obtained from the geography section of the ONS website (see weblinks).

Understanding Society (the UK Household Longitudinal Study), which began in 2009, is conducted by the Institute for Social and Economic Research (ISER) at the University of Essex, and the survey research organisations Verian Group (formerly Kantar Public) and NatCen. It builds on and incorporates, the British Household Panel Survey (BHPS), which began in 1991.

The Understanding Society COVID-19 Study is a regular survey of households in the UK. The aim of the study is to enable research on the socio-economic and health consequences of the COVID-19 pandemic, in the short and long term. The surveys started in April 2020 and took place monthly until July 2020. From September they took place every other month until March 2021 and the final wave was fielded in September 2021. They complement the annual interviews of the Understanding Society study.

This dataset contains Census 2011 Lower Layer Super Output Areas (LSOA) geographic variables for the Understanding Society COVID-19 study.

A file is provided for each wave of the Understanding Society COVID-19 study to date, containing the Census 2011 Lower Layer Super Output Areas (LSOA) geographic variable and a personal identification serial number (pidp) for file matching to the main Understanding Society COVID-19 study (https://beta.ukdataservice.ac.uk/datacatalogue/studies/study?id=8644">SN 8644). There are two types of waves: web waves have a filename postfix of _w and telephone waves have a filename postfix of _t.

In addition, this study also contains Census 2011 LSOA geographic variables that can be matched to a dataset released with the main Understanding Society COVID-19 study containing data taken from waves 10 and 11 of the main Understanding Society survey, specifically for the respondents in the COVID-19 study. This file is named jk_lsoa11_cv and as well as the LSOA11 geographic variable, it also contains a personal identification serial number (pidp) and a household identification serial number for both wave 10 (j_hidp) and wave 11 (k_hidp). Further details can be found in the Understanding Society COVID-19 User Guide.

This dataset contains Census 2011 Lower Layer Super Output Areas (LSOA) geographic variables for the Understanding Society COVID-19 study.

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.  Context Many 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. Some samples are tested on site and others are sent to scientific laboratories. Data TriageWe are sharing individual results, anonymised by mapping samples to LSOA (lower super output area).Data Specifications Each dataset will cover a calendar year of samples.This dataset will be published annually.The Determinands included in the dataset are as per the list that is required to be reported to the Drinking Water Inspectorate.
