Norfolk and Waveney: mapping digital exclusion

We're working to ensure every Norfolk resident has digital access to meet their needs. We want everyone to have digital opportunities in all aspects of their life.

To do this, we worked in partnership with:

•    NHS Norfolk and Waveney Integrated Care Board
•    Thrive by Design (part of Leeds and York Partnership Foundation Trust)

We have created an interactive map to show areas across Norfolk and Waveney where people are less likely have digital access opportunities.

The map uses local and national data to help us and our partners understand where to target activity and make best use of resources.

About the digital exclusion map

The map provides an index of digital exclusion, based on the combination of two factors: 

  1. Risk - factors that may have a negative impact on inclusion. For example, age, broadband coverage, and deprivation. 
  2. Capacity - factors that may have a positive impact on inclusion. For example, places that provide (or could provide) digital activities. 

The index then ranks every Lower-layer Super Output Area (LSOA) from 1 (most deprived) to 10 (least deprived). 

LSOAs are small areas designed to be of a similar population size. They have an average of approximately 1,500 residents or 650 households.

The interactive map will allow you to: 

  • Use local and national data sets to predict digital exclusion in LSOAs  
  • Filter different indicators of exclusion (such as age, deprivation etc.) 
  • Find the nearest place offering digital support for people (training, devices, data etc.) 
  • Understand more about the characteristics of excluded people and communities 
  • See where the gaps are in regional support offers.

Questions we're trying to answer

  1. Which areas of Norfolk and Waveney are most at risk of people being digitally excluded?
  2. Which areas of Norfolk and Waveney are at risk of digital exclusion for particular factors? For example age, deprivation, rurality, or type of internet use.
  3. What digital inclusion activities are already underway in Norfolk and Waveney and where?
  4. Which areas could be 'activated' to deliver digital inclusion activities?
  5. Which places can refer individuals to digital inclusion activities?
  6. What are the likely characteristics of excluded people and communities?

How to use the map

Use the map to explore areas of interest.

If you hover over an area on the map, it will display the full data for the area (that we have collected).

To select multiple filters, hold down the CTRL button and click each area you want to view.

How to use the map filters 

You can use interactive filters to filter the map. The filters enable you to view the data by:

  • District
  • Ward
  • LSOA
  • Primary Care Network (PCN) on the Digital Exclusion by PCNs page. A PCN is a group of GP practices working together, aligned to other health and social care staff and organisations. They provide integrated services to their local population. A PCN usually covers a patient population of 30,000 - 50,000 patients.  

Use the filters by clicking in the box next to the area you want to view. 

Use the downwards arrows to expand Districts and PCNs to select smaller areas.  

To select multiple areas at once, hold down the Ctrl button and click.

The map is built in Microsoft Power BI.

How deciles are used

Deciles break up a set of data into tenths.  

A decile is any of the values that divide the sorted data into ten equal parts. Each part represents 1/10 of the sample or population.  

Deciles are like quartiles. Quartiles sort data into four quarters. Deciles sort data into 10 equal parts; the 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, 90th and 100th percentiles. 

Why we use decile ranks 

Ranks are a way to categorise data. 

Using deciles to display class rankings on a pie chart makes more sense than percentiles. That's because a pie chart with ten categories would be much easier to read than a pie chart with 99 categories. 

What the map can tell you

Digital exclusion average

The digital exclusion average tells you the risk of digital exclusion. This is based on all the data collected. The score is weighted.

For more information on the weighting see the Information section of the map.

Key indicators  

The key indicator section is a summary of all the data we have collected to produce this tool. The tool is weighted based on the data. This section shows an average score of digital exclusion for the different headings.  

The key indicator section will update as you move around the map and select areas. For example, if you select a ward, district or PCN, the key indicator section will update to reflect the averages of the areas selected. 

For more information on the weighting see the Information section of the map. 

Why the map shows some areas are more at risk than others areas

Areas on the map may show as more at risk than others, even if there is local knowledge saying otherwise. 

We created the tool to showcase areas most at risk based on the data we have collected. The data is weighted. This is how it generates the digital exclusion score reflected on the map. 

However, there is also local information which the tool won't reflect. This is an important part of the tool for users to explore and challenge in their areas.  

For more information on the data sources see the Information section of the map.

About the Mosaic system

Mosaic is a system for the classification of households. It uses data from government and commercial sources.

It groups individuals and households together into 15 summary groups and 66 detailed types. This is based on the likelihood of them sharing similar:

  • Demographics
  • Lifestyles
  • Behaviours

Mosaic gives the summary groups and detailed types names and descriptions. These are of the likely characteristics of the households falling within these types.  

The map uses these Mosaic groups to allow more detailed analysis of characteristics of the different deciles. You can find this within the four Mosaic pages within the dashboard.
