Alright, here is the Spreadsheet I worked up.First- Methodology.
I took
Siggon Kristov's Exchange rate data and calculated everyone's GDP in Lodamun Dollars with the following Formula: GDPc*RATElod=GDPl
I then ordered the GDP's from Highest to Lowest, and divided them into 5 groups. The bottom three groups had 12 countries per category, while the top two had 11 countries per category.
I then created two indexes. One set at the GDPl for the lowest country in the top Quintile (which is Solentia, at roughly 296 billion) and the second was set at the mean GDPl, (which was Trigunia, at 252.6 Billion). For the first index, I divided each GDPl by Solentia's GDPl, and then multiplied by 100, to produce an index which ran from 166.71 to 0. 10 countries exactly are greater than 100 in this index, the remaining 48 countries are below 100, though except for the lowest 3 countries, the lowest index value is 30.51. This means that each country's GDPl is that much more or less, as a percentage. So, in this case, Republicca Istaliana (Quanzar, on the list, or Country 39) has the biggest economy, and is 166.7 percent of Solentia's. In this case, Solentia is just the country which sits at the lowest point in the top Quintile.
For the Second Index, I divided the (country's GDP in LODs by Trigunia's) times 100, which is the average economy over the entire world. In this case, there are 34 countries with bigger economies than Trigunia's and 23 with smaller economies. On the Indm, the index runs from 196 (or roughly twice as big) to 0, though above the bottom three countries, the lowest indexed score is 35.
The reason for these two different indexes is because then I used the
World Bank's GDP data for September 2014 to create similar indexes. For the data listed by the world Bank, I created a Quintile Index and a Mean Index. Both of these should give us a means for comparison, assuming Terra as a whole is similar to Earth as a whole. Interestingly enough, the Quintile Index had Chile at the bottom of the Quintile Index and Thailand (a country with a bigger GDP than Chile) as the index point for the Mean Index. The answer to this curious situation is that the economies of the US, China, Germany and Japan are so incredibly huge that it pulls the mean WAY off the median income, where would have otherwise expected it to be found. The US is especially problematic in this activity, especially in terms of the Mean Index. Since the Quintile Index is merely a count measure, rather than any sort of mathematical measure, it is not problematic there.
Now- the point of this process is to see what country your country would look like if Terra were transplanted to Earth. Based on these indexes, most of our countries are what we would call "Developing" Countries. That is not a problem- Most of the countries of the world are not advanced economies by any stretch of the imagination. But if your country is in the top quintile of Terran nations, you could generally expect to act like those in the top quintile of Earth's nations as well, and so forth. I included the Mean index to give us some different ideas, and take into account a lot of the differences between earth and Terra.
In no situation will a country approach the GDP of the US comparatively. Or China, or Germany. But then again, you could aspire to Saudi Arabia Status, or Belgium status. And really, in terms of size of the economy, that really isn't so bad. In the Quintile analysis, there is a lot more room... The top of this index are sitting at around Venezuela, Denmark, Malaysia and Singapore levels.
Also, I should point out, that these are just guides for your country. You could go up or down a few degrees in either index.
The ultimate goal is that you should use these indexes to begin to research countries LIKE yours in the real world, in terms of GDP, to get an idea of how they do their spending respectively. It will help you RP your country more accurately, if you are so inclined. Or not. Check out the Spreadsheet, get some ideas, and hopefully it is helpful. Perhaps some of our friends in Moderation can publicize this work.
