It's the divorce rate.

[KostasKouvalis]

Either brides or divorce. I wanna say brides, but I think it's Divorce as I know Nevada's is very high

[SaoirseS]

I was going to say average number of firearms per household, but Texas, Missouri, Florida and Kansas aren't on there.

[purplepoppy]

Very tempted to go with marriage age but i think it's first car accident.

[exitseven]

I guesses the age of the first car accident.

[xawyx-3]

I'm not from US so I can't be sure, I voted for the number of divorces...

[xawyx-3]

Ah, the update... so my guess is right ;)

[msc545]

I think those might be the divorce rates - just a guess.

[Cidknee]

Nice shot!

[captain_voidwalker]

Can rule out marriage age thats been trending older for decades, and can rule out number of divorces because thats 900 out of 1000. So it's gotta be vehicle related and I'm gonna guess it's first accident.

[andreasderjuengere]

The exact number of people in the respective state who still have trust in your present ''President''?

[OneViewpoint]

Fried Bologna sandwiches consumed annually per capita.

[Lliam]

I'll go for the number of vehicle accidents per 100,000 people.

[RareBreedOfMan]

Average number of 1000 vehicle accidents that happen

[Kelly6]

@AviatorTom age of bride sounds accurate to me

[NathanDavis]
