All the foreign nationals in Luxembourg

I came across a page here the other day from the bureau of statistics in Luxembourg, showing the number of foreign nationals in the country. The most interesting part is the number of Portuguese there, a full one in six (at least). Turns out this goes back to the 1960s.

The page shows the numbers for 1981, 1991, and each year from 2001 onward, so with a bit of easy Excel work the years in between can be estimated. That gives us the following charts.

First the total population, Luxembourgers, foreign nationals, and each country after that:

Then remove the total population:

Now remove the Luxembourgers:

And finally the individual foreign nationals by country on their own.

The steady decrease in Italians is also fairly pronounces, German and French increase bit by bit over the years too.
