I gathered the following statistics from Fiscal Data from the Ministry of Finance from 2009 to 2017. I will let the data speak for itself.
| Year | Grant/GDP | Grant/Revenue | Gov’t Revenue/GDP |
| 2009 | 5.10% | 19.41% | 31.30% |
| 2010 | 2.40% | 13.97% | 19.90% |
| 2011 | 2.10% | 10.06% | 22.80% |
| 2012 | 1.60% | 7.48% | 23.20% |
| 2013 | 0.80% | 3.80% | 20.80% |
| 2014 | 0.70% | 3.29% | 21.80% |
| 2015 | 1.90% | 8.39% | 22.90% |
| 2016 | 0.70% | 3.39% | 20.00% |
| 2017 | 0.70% | 3.43% | 17.10% |
From 2009 to 2017, grants averaged 1.74% of GDP and 8.14% of government revenue. Do note though, that these figures do not include grants to private organizations or citizens.
Here’s the information in a beautiful chart.
Do have a nice day.
