The reasons are complicated and historical. Thomas Edison chose 110v because that was the voltage he needed to light his lamps. Other countries mostly seem to have followed German standards which allowed cheaper distribution over longer distances at a higher voltage.
To supply 100W of power at 110v requires approximately twice as much current as it does at 230v and the higher the current, the larger the conductors need to be to carry it and the greater the line losses.
