The word 'trivia' is derived from the latin word 'trivium', which means 'three roads' or more colloquially 'crossroads'. The junction of three roads is where common people meet, and exchage small, inconsequential bits of information or hold conversations that were general, interesting but unimportant in nature.
A trivia could be an information like India having only 2.2% of the Worlds total land mass, but is home to 16.5% of the World's population.
Another trivia is that Kuwait is the 3rd crowded nation in the World, with Singapore and Israel taking the first two places. India is ranked 33rd.
