No, you need to have units on your data. Without units, numbers mean nothing. You select a country, and then you're presented with a list of other countries and some numbers. It's not clear that these are lifetime immigrants or permanent residents. There should be a title on the country info box "Total lifetime immigrants" or "Total lifetime emigrants", and ideally a legend at the bottom defining what that means.
It's also confusing in that the number format follows a European convention of using decimal points rather than commas in between every three digits the numbers, though I can accept that localising your site isn't a big concern.
