50% of The UK's Population Live Inside This Circle

Map created by @election_data at the request of Mark Pack

The map above shows how far out from London you have to go before you get 50% of the UK population (not including the French of course).

The map was created by @election_data who state that:

There so some sensitivity depending on where the line cuts across Birmingham and Bristol but 10km either side of this line gets 49-51% roughly

Moreover, 20% of UK population live within 50 km of London and 33% within 100 km.

      The Radius is the distance from the centre outwards. Hope that helps.

    Fascinating. From this it follows that if you moved the circle NW to centre on, say, Luton, you ‘d get more than half; and you would therefore make it smaller to get exactly 50%.
    Which leads towards what the relevant ‘optimisation’ question would be. How about, Find the smallest possible circle which would enclose precisely 50% of UK population; state its centre and radius?

    literally just put this comment on youtube, hit return and thought ‘i wish i had checked first’:
    “would work great in britain where we got 30 million people all wanting to be in the same 100 sq mile corner of the country.”

    well i checked afterwards and it seems i wasn’t so far off.
    thank you for your map and website.
    i’ve added it as a bookmark,
    ian
