More than VS Greater than

[sumithshah]

Can someone elaborate about the usage of more than vs greater then?

I know grater than is used for comparing numbers ( but can we use it to compare population? Population of X is greater than that of Y?)

Also, is there a rule which explicitly states the usage of more than / greater than?

Thanks
