I believe your interpretation of this data is incorrect. Given the relatively infrequent contact children would have with magnets strong enough to be dangerous as compared to all of these items that are found in every home in America and most certainly in every home with children in America the rates indicate the opposite. Think of all the confounding factors here such as ages 1 month to 15 years - older children are far more likely to be injuring themselves with knives, the population at risk from these magnets is generally under 10 years old. Think of just how rarely a child in America makes contact with one of these magnets as opposed to the other objects. All children in the school age range are practically forced to be in contact with a pencil for hours a day every weekday for ten months. PS: I do really appreciate that you looked these numbers up though.
