Where They Started redraws the UK map to show which counties have produced the UK’s Olympians over the decades. A whole host of trends are visible on the map. Some aren’t very surprising – boxers tend to come from big cities, while sailors often hail from the coast. Others are less obvious, such as Northern England being good at swimming, or South Wales being good at gymnastics. Counties are scaled according to absolute numbers: the more athletes a county produces, the bigger it is. Where They Started includes all the Olympians – around 4,000 in total – with data that extends back to the first “modern” Olympics in 1896. The map was produced for Join In Local Sport by Kiln, with data provided by OlyMADMen.
