From the Pew Research Center:
“As of the end of 2016, 97 out of 167 countries (58%) with populations of at least 500,000 were democracies, and only 21 (13%) were autocracies, both post-World War II records . . . Broadly speaking, the share of democracies among the world’s governments has been on an upward trend since the mid-1970s.”
