Guess it... or ask a queston.!!!

To be even more exact it is a Civil War draft lottery machine from Ohio.
A similar draft caused bloody riots in New York.
Irish labourers thought that if the North won a war against the south, freed slaves would come up and take their jobs.
What gave them that idea? The newspapers.

What does this graph show?
Don't do a google image search, as it will find it instantly.

I've added some text now and it no longer finds it.
That's handy.

You would have thought that by the 70s they would have used a computer, but in fact they used something even less hi-tech than the village hall tombola boxes used a century before.. For the Vietnam War, they used a glass bowl.

Side Scale. Not population, but number of people doing something.

Does the botom row of numbers represent years.???

"Years of" something.
Everything in the graph relates to one year. The year 2000.

IOW, it is the ages of people in the year 2000? With the other being the amount in each "age bracket" that is doing something? If so, the matter of what they are doing. The highest hump is circa 70 to 90 years. There's also a mild elevation around the time of newborns and then it goes down sharply only to ascend again.

@CC
That is getting very close to the answer. Ages is the bottom row.
But why would the ages in the year 2000 go down sharply and then ascend again?
Ages of people doing what?
Better be quick or someone, I'm not saying who, will steal the prize.
