The title supposedly refers to the ratio in the United States between young and old, perhaps with a nod to Sun Tzu's art of war, "if our forces are 10 to the enemy's, surround him; if five to one, attack him."
The lyrics - "The old get older but the young get stronger, it may take a week but it may take longer. They've got the guns, we've got the numbers" - acknowledge the latent power of youth and reflect Morrison's belief (like many of the Summer of Love generation) that music could change the world.
