there are 46259 people aged 34 or younger and 63608 aged 44 or younger, so the median age group is 35-44. You could go further by making some assumptions to try to make an estimate of the year within that - e.g. if you assume uniform age distribution within bins, the median age would be (53885-46259)/17349 = 43.96% of the way through the range
