The floor space and employment survey collects data on all businesses, floor space uses and employment numbers for every building or property in the City of Sydney local area every 5 years. The 2022 FES was the fourth full survey within the current City of Sydney local area boundaries. Previous surveys were undertaken in 2007, 2012 and 2017.    Each business establishment is classified using a composite city-based industry classification to report on the various industry sectors across the local area, categorised by the main function of a business. The classifications are based on an expanded version of the Australian and New Zealand Standard Industrial Classification (ANZSIC) 2006.    For more information on the floor space and employment survey, visit the City of Sydney website.
