The map shows nearly every leader tweets throughout North and South America but adoption of the social networking site is lighter among European, Asian and African leaders.
The report claims 75 percent of world leaders now tweet but those numbers are a little fuzzy because the list includes some heads of state whose roles are largely ceremonial. Some of the leader’s accounts are managed by assistants rather than by the leaders themselves.
