Boys! To Putney
The election data noted below also has a lot of constituency by constituency demographic data. One interesting one is the number of women per men (as according to the 2001 census). Almost all of the constituencies with a large female/male ratio are also those with the most pensioners, as men, after a lifetime slogging away whilst their women powder their noses, die earlier. There is one glaring exception however, Putney. 15% more women than men, but a relatively young population. See chart:
Ps There are only 57/600 constituencies that have more men than woman. Aldershot, presumably because of the troops is the leader. I was going to make a snide comment to the effect that contemporaries of mine would not be surprised to learn that Oxford (West) was one of them, at 0.98, but bizarrely Oxford (East) is the opposite, at a respectable 1.06.
