Just divide the 104 Billion Dollar Budget by 1.4 Trillion Dollar Economy. However, those numbers are obsolete. We've shunk and fallen behing FRANCE!!! The thing to find out is if France squanders the equivalent of 104 Billion dollars on Socialistic Social Engineering and EnvironMentalism, turning the Revenue Stream into the Waste Stream like CA's legislators have been doing!!!
I'm not sure where you're trying to go with this, FF. About the only thing you can determine conclusively (after crunching numbers) is if the relationship is increasing or decreasing over time. Without even crunching the numbers, I would bet they the budget is increasing as a percentage of GSP. Comparison of State percentages relative to Federal percentages aren't meaningful, as the nature of the expenses are much different (e.g. States have no national defense expenditures) and GSP is derived differently than GDP with respect to inclusion/exclusion of government employees.
I'm an old number cruncher from way back.... but what are you trying to demonstrate?
