'Ideal weight' is determined more accurately by height and bone structure rather than the age of the individual.
Average weight for a 9 year old boy is 62 pounds; however, obesity - being overweight - cannot be determined this way. You have to take into account his height to get any idea of his body fat index, and it's best if you go to a doctor for that. If you're concerned that someone you know is overweight, it might be a good idea to encourage them to participate in sports - children who are overweight have a very hard time loosing weight as adults and it can cause serious health problems later in life.
