Cultural Victory

So what is the 90% of cultural victory measured in? Playing my first game... I have the most influence in all 16 sectors of the map, but still no cultural victory. In the "menu" screen for cultural victory it states "12 mnts". I have no clue what that is supposed to mean. 
Do you actually need 90% of total influence in the world, as opposed to controlling influence in 90% of the sectors?
