Statement

This assessment framework recognises that social vulnerability to flooding is influenced by a mix of personal (e.g. disability or age), environmental (e.g. elevation of housing, presence of green space) and social factors (e.g. levels of income, tenure or extent of social networks). When combined, these affect the degree to which flooding may affect the well-being of individuals and communities.

The index of social vulnerability to flooding comprised 34 indicators in total, relating to 14 thematic domains (Age, Health, Income, Information use, Insurance, Local knowledge, Social networks, Tenure, Mobility, Physical access, Crime, Access to services, Housing and Green space). The main sources of data were Scotland’s Census, Scottish Neighbourhood Statistics, SEPA’s flood data and Ordnance Survey data, in addition to some other information. The indicators were combined to produce an index of social vulnerability for the whole of Scotland at the neighbourhood level (using 2001 Data Zones). The index of social vulnerability to flooding was combined with flood-hazard exposure data, to produce a final index of flood disadvantage. The flood hazard exposure information takes into account different sources of flooding (coastal, river and surface water) and different return periods. Social vulnerability to flooding and flood disadvantage were then categorised into six classes, based on the deviation from average Scottish values, ranging from extremely low to acute.

This digital dataset includes 5 main components:

1. Vulnerability Indicators - the 34 indicators used to calculate the index of social vulnerability to flooding. In order to calculate the index, the indicators were standardised, weighted and combined together.

2. Social Vulnerability to Flooding - the standardised index of social vulnerability is provided, together with the values of the dimensions of vulnerability (sensitivity, ability to prepare for, respond to and recover after flooding). For the index and its dimensions, 0 is the national average; positive values indicate above-average and negative values mean below-average levels of vulnerability, sensitivity, enhanced exposure and inability to prepare for, respond to and recover after flooding.

3. Percentage of Households Exposed to Flooding - the percentage of households in the data zone that are located within flood maps representing the extent of different flood types (coastal, river, surface water) for any type of flooding and for different return periods (1 in 10; 1 in 25/30; 1 in 200; and 1 in 200 years including the impacts of climate change).

4. Flood Disadvantage - the combination of social vulnerability to flooding and the percentage of households exposed to flooding by data zone. This includes the values of the standardised flood disadvantage index for different types of flooding and varying return periods, where 0 is national average, positive values indicate above-average and negative values mean below-average flood disadvantage. The value of -999 code means that the data zone is not exposed to a given type of flooding.

5. Geographical Location - the rurality of each data zone according to the Scottish Urban-Rural Classification (2014). A classification of the coastal and inland areas, is also included based on the location of the data zone population-weighted centroid, and using three distance bands from the coast: 1 km, 2km and 10km.

This project applied the same framework as the first assessment of flood disadvantage in Scotland (Lindley and O’Neill, 2013) and an earlier assessment of social vulnerability to climate change impacts (Lindley et al., 2011). However, this research modifies the original methodology to include more recent datasets to represent the indicators of social vulnerability and flood risk. Therefore, the results of this research should not be compared to the earlier work.
