International Idea- Citizen Participation in Government

I chose the countries Brazil,Cambodia,Columbia,Guam,Italy,Kuwait,Nigeria, and of course the US. I think that compared to other countries, the US is definitely has the highest rating for involving citizens in the decisions of their government but the voter turnout ratings shocked me. This only makes sense because this notion of voting and a democracy is what the US was founded on. Brazil was first in my search. It had the highest percentage of voters who turned out. The countries Kuwait, Italy, Guam, and Cambodia do not have any statistics meaning that their people cannot vote or did not turn out at all. I am surprised that Italy didn't have a percentage at all.
