A team of geodata experts have created a map of the most popular surnames around the UK. As well as mapping the distribution of names from the electoral roll, Twitter account surnames have been included. The results show a marked difference between the two, with Twitter names diverging from national and regional stereotypes. Of electoral roll names, Smith dominates in England, Jones in Wales, and Scotland is dotted with Campbells and Robertsons. Switch to Twitter, and many more non-British names appear.
