Abstract
<div>National Exposure Information System (NEXIS) Residential Dwelling Density is a set of four raster layers representing the density of residential dwellings across Australia at different scales and resolutions. A dwelling is defined as self-contained suites of rooms including cooking and bathing facilities and intended for long-term residential use. Such dwelling units include houses-detached buildings used for long-term residential purposes-and other dwellings including flats. NEXIS collates the best publicly-available information, statistics, spatial and survey data into comprehensive and nationally-consistent exposure information datasets. Where data is limited, models are used to apply statistics based on similar areas. Exposure Information products are created at the national, state or local level to understand the elements at risk during an event or as a key input for analysis in risk assessments. NEXIS products are not intended for operational purposes at the building or individual feature level. Its strength is to provide consistent aggregated exposure information for individual event footprints or at standard community, local, state and national geographies such as the Australian Bureau of Statistics (ABS) Statistical Areas (SA) or Local Government Areas (LGA). NEXIS Building exposure information consists of Residential, Commercial and Industrial buildings. This information can be used to understand the type, use, age and structural characteristics such as number of storeys, roof type and wall type of the building stock nationally. Building exposure information can also be used to estimate population attributes such as the number of occupants, household income and other demographic indicators, as well as economic impacts based on building construction and replacement costs. The NEXIS Residential Dwelling Density is a national grid-based representation derived from the number and distribution of dwellings produced from the NEXIS residential buildings data. </div><div><br></div><div>Dwelling density is available as a web service displaying the aggregate number of dwellings, at four different raster scales and resolutions, to show the distribution and density of residential dwellings across Australia. Resolutions include 100m, 500m, 1km and 2km rasters.</div><div><br></div><div>Resolutions:</div><div>1. Number of residential dwellings per 100sqm.
