The result was a majority of 1,269,501 votes cast in favour of leaving the EU.

[17,410,742 LEAVE, 16,141,241 REMAIN]

MAPPING THE RESULTS

Using ESRI's ArcGIS Pro and ArcGIS Online,  I have created a 'WEB-MAPPING APPLICATION' of the referendum results that can be viewed on PC or Mac, pad or phone. The results were published by local authority districts for England And Wales, council areas for Scotland and by parliamentary constituency for Northern Ireland.

Statistical methods

Each statistic is presented in seven classes according to the following statistical methods:
        These methods are easily understood but may not relect patterns within the data.
        The following two are more complex but may be more enlightening.

THE MAPPING INTERFACE

Legend control

The map first appears without a legend. This appears to be an ESRI setting, but is easily remedied. The legend control appears in the top right of the map, highlighted in red on the image below. Click on the control and the legend appears. It can then be minimised or removed by controls highlighted in yellow and red on the second image.
 
Legend 1   Legend 2


Layer control

Each of the statistics, and statistical methods, desribed above, is represented by an individual layer. These layers may be switched on or off through the layer control, highlighted in red on the graphic below.

Each layer is semi-transparent to permit the OS raster backdrop to show through. As a result only one layer should be selected at any one time.

District names layer

In contrast to the other layers, this layer may be selected in conjunction with any other layer. Note though that this carries an increasing performance hit as you zoom out.
