The time of women's puberty and menopause is a key health metric for a given population. If it's moving up or down something's likely to be very wrong (e.g. exposure to pollution, hormones in the food/water supply). It would be negligent not to track it for health reasons. There seems to have been something shady going on here. I won't comment on that, but the government tracking this isn't per-se strange or unwarranted.
