UK population is roughly 70 million, population of Europe roughly 700 million, is that a fractal?

No, fractals are much more symmetrical.

Fractals are a curve or geometric figure, each part of which has the same statistical character as the whole. Fractals are useful in modeling structures (such as eroded coastlines or snowflakes) in which similar patterns recur at progressively smaller scales, and in describing partly random or chaotic phenomena such as crystal growth, fluid turbulence, and galaxy formation.


That is called a FRACTION (in this case 1/10th)

A fraction (sometimes, a common fraction) is a way of expressing a number that is a ratio of two integers.

It is also a ratio and a percentage of a whole.

No value can be gained because of your choice to use estimates. Any signficance is lost in the variables of the term 'roughly'.
