Ethnic group statistics from the 2011 Census

Lower layer Super Output Areas (LSOAs) are made up of groups of OAs, usually four or five. They comprise between 400 and 1,200 households and have a usually resident population between 1,000 and 3,000 persons.Using Census 2021 data, some changes were made to 2011 LSOAs as a result of population and household changes since 2011. New 2021 LSOAs were created by merging or splitting 2011 LSOAs to ensure that population and household thresholds were met.Outputs from Census 2021 are for 2021 LSOAs and are made up of unchanged 2011 LSOAs and new 2021 LSOAs.There are 33,755 LSOAs in England and 1,917 in Wales.

This dataset consists of flower density values of common British plant species. The data were collected during field surveys taking place from February to October in 2011 and 2012. The majority of field sites were located in the south of England. The data were collected under a project named 'Agriland' ( Linking agriculture and land use change to pollinator populations) based at the University of Bristol, as part of the UK Insect Pollinators Initiative. The Insect Pollinators Initiative (IPI) was funded by Biotechnology and Biological Sciences Research Council (BBSRC), Natural Environment Research Council (NERC), Department for Environment, Food and Rural Affairs (Defra), the Scottish Government and the Wellcome Trust, under the auspices of the Living With Environmental Change (LWEC) partnership.
