Compute Female proportion in each district in long format data in Stata.

I have a long format dataset where it has 5 variables:
did---district id
sid---school id
id--student id
age --student age
count-Bonus count
male--student gender(1-male;0-female)
Now, I want to compute female proportions for each district.
Thank you for your Stata code.
