History:
Smiths widespread presence is mainly because people chose to move. Think of the huge number of people who left England, especially during colonial times. Lots of Smiths went to America, Australia, and other British colonies for better chances, making this surname common there. The same happened within Britain itself, as people moved for jobs or a better life. This surnames popularity in English-speaking countries shows these migrations. The main reason for this surnames global spread is people voluntarily seeking better lives; their settlement patterns follow general population trends.
