I did not quite understand the solution. I don't understand the solution for 2. Is there a different way to explain it?

The total number of people in 1992 was 4 times more than in 1989.

For Montana, the number of people stayed the same. That’s why its 1989 bar is 4 times bigger than its 1992 bar.

For any other place:

  • If the 1989 bar is smaller than 4 times the 1992 bar, then more people came in 1992.
  • That’s true for every place except Montana.

So, 12 places had more people in 1992. Only Montana stayed the same.
