Median message lengths, in characters, for different groupings of districts.

<p>Combining Northern England with other parts of UK to form (a) Northern UK and (b) Northern Great Britain results in median message lengths equal to that of Southern England. (c) Northern England, by itself, would have the longest median message length but (d) grouping it with the Midlands results in the same median message length as for Southern England. The median message length of the (e) union of the Midlands and Southern England is smaller by one character than that of Northern England, consistent with the stereotype. Computing the median message lengths of the (f) other home countries yields three groups: Southern England, Wales and Northern Ireland, the Midlands and Scotland, and Northern England.
