    2012 appears once as a birth year and once as a surveillance year. The graph says that they only ever surveyed 8-year-olds, since the birth year is always 8 less than the surveillance year.

          It’s probably a dataset that collected every 2 years, but only labeled every other bar to prevent the graph from being overcrowded.

          Not a great decision, but not terrible.

          Although, I’m a bit concerned for Lemmys graph comprehension skills.
