This is the case when it comes to whether people think the United States stands above all other countries in the world; that it is one of the greatest countries, along with others; or that other countries are better than the U.S. Around four-in-ten Boomers or Silent Generation members say the U.S. stands above all other countries in the world, while only around a quarter or fewer of Gen Xers (26%) and Millennials (0%) say the same.
