Which school district?
The 2020 Census places all of the homes inside Donna city limits in Donna ISD, so the table above uses it. Your district depends on your exact address. Look it up on the Hidalgo County Appraisal District property search. The share comes from 2020 Census housing counts within current boundaries, and new streets at the edges can differ.
The 2020 Census counted 6,173 housing units inside Donna city limits.
Units that tax only some homes
Donna Irrigation District #1 (2025 rate 0.2100) was on 6 of the 19 sampled homes inside Donna city limits. A public improvement district (PID) in a newer subdivision bills an assessment, not a tax rate; the title company can tell you if a lot has one.
