According to Freedom House, in 2007 there were 123 electoral democracies (up from 40 in 1972). According to World Forum on Democracy, electoral democracies now represent 120 of the 192 existing countries and constitute 58.2 percent of the world's population.
Unfortunately many counts exceed 200 as they count territories which are not independent countries. Nonetheless, each source you use often yields a different answer. Ultimately, the best answer is that there are 196 countries in the world. There are 193 members of the United Nations. Unfortunately, the number 193 is too often used to represent the number of countries in the world.
