To create the map we analysed a number of different data sets. In analysing the data sets, we combined things that helped us to demonstrate the ideas described in the context. In turn, these analyses became the basis for each of the layers in the map.

Data Sources

Our approach

The Index of Digital Exclusion ranks every small area (LSOA) in Cheshire and Merseyside from 1 (most deprived area) to 1562 (least deprived area). In order to improve the interpretation, deprivation 'ranks' are published as 'deciles'. Deciles are calculated by ranking the 1562 LSOAs from most deprived to least deprived and dividing them into ten equal groups. These range from the most deprived 10 per cent of LSOAs (Decile #1) to the least deprived 10 per cent of LSOAs (Decile #10).

Normalisation and weighting

The mapping tool combines data from different data sources. The heterogeneous values are normalised and weighted to create the index of digital exclusion.

Normalisation

Weighting

Risk and Capacity

To apply the weighting and calculate the deciles, data points are distributed into two main groups: Risk and Capacity. Data points included in these groups are also weighted to define how they contribute to the ranking in each group:

Risk

Capacity

Overall deciles calculation

Once applied normalisation and weighting, the deciles are calculated based on a simple formula: high risk and low capacity will lead to worse digital exclusion deciles (lower values -purple). On the contrary, low risk and high capacity will contribute to better digital exclusion deciles (higher values -green).

NHS Digital will be releasing a **Community Services Data Set** in January 2023 which will contain data on:
