Geostrategic power report - foreword

So following after this post, in step wise fashion over the coming Days of week 11, will be the roll-out of my geostrategic power report. The goal with this report have been to define, calculate and assign a numeric geostrategic power index for each of the worlds countries based on a few key macro variables.
It is of course only a model and a model can never be a true reflektion of reality and especially something like power which in itself is open for discussion how to define it and what it really means.
My respons to this situation have been to construct something quite simple which is always a good characteristic for a model, with easily and readily available data as a basis for made calculations and so the model is also possible to grasp easily and not a "black box" creation.
Nevertheless despite its relative simplicity i think the results from the calculations makes a lot of sense. Remains to be seen what audiences think though. 
I have also adopted a "hard core" view on power meaning that i dont consider soft variables e.g. cultural influence in my power index. However i include as part of my power index such variables as population and total land surface area of each country as these variables clearly weighs in on the common perception of what makes a country powerful, Think e.g. Chinas and Indias 1+ billion people and a lot of us feel a bit of a worry and maybe some relief that my own home country does not share a border with those population giants.
More detailed information and explanations will follow in step with each section of the released report.

I have also calculated a centroid or center of gravity for each variable in the calculations and of course for the main power index itself to visualize where on the surface of the Earth these center positions is currently located. These centroids will probably be a subject for further calculations ahead to incorporate and visualize historical and future forecasted developments.
