In a recent post on his blog Terence Tao had the idea to scale the US budget and other data with the scale factor of 3/100 million. In particular the US population of 306.44 million shrinks -if one uses this factor- to about 9 people (306.44million/(100 million/3) =3.0644*3 =(approx) 9 people) which is about one to two average families. He did that in order to facilitate the comparision of the US-budget with a normal one-to-two family household budget.
I found that a useful visualization experiment and thus tried to do the same with the german budget – that is I used a scale factor which scales the population of Germany (originally 82.099 million down to 9, i.e. I used the factor 0.000 000 11 = 11/100 million (82099000*0.00000011 = 9.03..) and multiplied it with the corresponding amount in euro and in US-dollar (since I did this with an online currency calculator on different days there may be some variations). All calculations are without guarantee and I hope mistakes will be pointed out to me in the comment section. I abbreviate the number 1 billion = 10^9=1 000 000 000 with the letter B. So 1 B$ means 1 billion US dollar. Interesting figures are highlighted with an ->.
The revenues and spending in Germany are divided into the federal government (“Bund“) on one hand and the federal states (“Länder“) and districts (“Gemeinden“) on the other hand (here details in german). Both shares are very roughly the same. For example in 2005 the spending was
Bund 294.0 BEuro
Länder 259.3 BEuro and Gemeinden 153.3 BEUro
alltogether: 625.9 Beuro
I found no survey on the federal states and districts, besides this overall Länder and Gemeinden revenues and spending. The federal states are for example in charge for schools, I think they do not pay for military (?). However besides this the federal government budget (“Bund“) gives already quite a good overview over priorities.
I recovered the other data (like GDP etc.) to a great part from the federal office of statistics which hosts confusingly also the statistikportal. The website of this federal office is -mildly put- uncomfortable. That refers not only to the overall webdesign like for example it took me more than quite a while to find detailed readings on the GDP (since I started out at the statistikportal), but also to the overall accessability of data. For example I was also interested wether things like the Abwrackpraemie raise or lower the GDP or wether paying for volunteering could raise the GDP in some way…(just as a trick for the upcoming elections…), however in this GDP document it is even not possible to deduce within a reasonable amount of time which positions are summed over and which are subtracted.
But back to the budget discussion. The federal government (“Bund”) budget (Bundeshaushaltsplan) which is as explained above about half of the overall german budget is available as a pdf document here. From it one can read off a lot of the following figures (I tried approximately to reflect the ones Terence Tao chose). If there is no other link provided then the corresponding number in the below list is from this document.
Example: If the federal government (“bund”) has a budget of 283.200 BEuro for 2008 then this is a scaled budget of 283 200 000 000 Euro * 0.00000011 = 31152 Euro. Since this is as explained above about one half of the overall german budget the state family of 9 has thus an approximate budget of 2*31152 Euro =
->(approx) 60 000 Euro (per year).
That is 2* 383.343 B$=2*383 343 000 000$ which gives a scaled budget of 2*42167 $ =(approx) 84 000 $ (per year) which is in the same range as the US budget of 75 000 $ (per year), which appears in Terence Taos list. Compare these 60 000 Euros to the salary of 500 000 Euros which are not enough for the best.
The green number is a real budget number which is rescaled to the budget of a “family of 9 people” in Euro, the blue number gives the same amount in dollar so that it is comparable with the US budget in Terence Taos list.

- cars and electricity: economic stimulus for electromobility: 0.5 BEuro 0.706 B$ 55 Euro 77 $
comment: de facto this amounts to a percentual decline in investments in renewable energies, which seems to be an overall trend – the International Energy Agency estimates that
“for 2009 as a whole investment in renewables could drop by as much as 38%, although stimulus provided by government fiscal packages can probably offset a small proportion of this decline”
