I think I recall reading that Finland was losing its population because not many people are having kids and there is little immigration.
Do you mean the whole earth or just the crust/surface? The answer varies on this and other questions. The most abundant single mineral in the crust is quartz, unless you lump all of the types of feldspar together as one mineral, in which case the most common mineral is feldspar. The most common mineral in the mantle is olivine. The earths core is made up largely of molten iron, so native iron would be the answer there. Some mineralogists don't regard molten iron as a true mineral.
Germany ?

I believe the answer is Japan.
