Abstract
Background: The annual cut-off date of birth for entry to school in British Columbia, Canada, is December 31. Thus, children born in December are typically the youngest in their grade. We sought to determine the influence of relative age within a grade on the diagnosis and pharmacologic treatment of attention-deficit/ hyperactivity disorder (ADHD) in children.
Methods: We conducted a cohort study involving 937 943 children in British Columbia who were 6–12 years of age at any time between Dec. 1, 1997, and Nov. 30, 2008. We calculated the absolute and relative risk of receiving a diagnosis of ADHD and of receiving a prescription for a medication used to treat ADHD (i.e., methylphenidate, dextroamphetamine, mixed amphetamine salts or atomoxetine) for children born in December compared with children born in January.
Results: Boys who were born in December were 30% more likely (relative risk [RR] 1.30, 95% confidence interval [CI] 1.23–1.37) to receive a diagnosis of ADHD than boys born in January. Girls born in December were 70% more likely (RR 1.70, 95% CI 1.53–1.88) to receive a diagnosis of ADHD than girls born in January. Similarly, boys were 41% more likely (RR 1.41, 95% CI 1.33–1.50) and girls 77% more likely (RR 1.77, 95% CI 1.57–2.00) to be given a prescription for a medication to treat ADHD if they were born in December than if they were born in January.

The teacher can tell you whether your child is one of the younger children in the class without compromising personal information. I see nothing in this study that says the actual birthdate is relative, but rather where the child falls in age with respect to the cutoff for the academic year. Still see no need for requesting birthdates.
In all fairness, OP didn't ask for actual birthdates.
OP asked how many kids in her child's class had a birthday that fell before a certain date.
Her exact words:
"I asked how many students have birthdays prior to X date. Just the number of students. My reason - wanting to know where my child stands age-wise in the class."

This could be helpful information for a parent to have. A teacher might believe that it it completely normal for a group of 1st graders to have a wide range of maturity levels...but a parent might have real developmental concerns if her child (who is 14-16 months older than most classmates) is considerably less mature.
A parent might have legitimate motivations to assess her child relative to age in a way that a teacher might not. I don't think it means the parent has some sort of nefarious motives.
