how to merge several layers and attributes

how to merge shapefiles and attribute tables...?

so i have a parts of the world that i want to bring together. and i tried 'merge' but instead of overlaying the attributes, it just makes a more attributes.

so, for example, i want to merge USA and Canada
suppose there are 3 columns (both datasets have the same 3 columns) name, area, population.
when i merge them, instead of aligning the columns, so that it makes the list longer, it creates 10 columns. does that make sense?
so it looks like this:

name | area | population | name_1 | area_1 | population_1 |
usa      123   123123123     can          123       123123123

but i want it to look like this:
name | area | population
usa      123   123123123 
can      123   123123123


i just want to be able to merge them together so that the attributes also come together in the same column too .... which wouldn't be a problem to do manually if i had just one or two datasets and 3 attributes, but i'm merging together about 15 layers, each with about 18 attributes.

do you know if there's a way to do that? i think there is a very easy way to do this, but i just can't seem to figure it out for the life of me. tips anyone? i'm looking to get this done by 12/28!
