Official portals are useful but not perfectly synchronised. A home page may reflect a new district name while an internal history page still uses a 2022 mandal list. An agriculture page may present 2011 census data recalculated for a later boundary, or may quote an undivided district. Read the page's update date, notification reference and geographic scope.
When two official pages conflict, prefer the later gazette for legal boundaries and headquarters, then the current district portal for administration, and then dated departmental statistics for sector figures. Record what each source actually proves. A site map proves location; it does not prove production, project completion or final population.
Worked example: An official district profile may mix 2011 census numbers, 2026 officeholders and pre-split area figures on one webpage. Do not assume every row shares the same date. Record the data vintage and boundary for population, area, crop output and mandal count separately. If the profile contradicts a Gazette or current directory, use the more authoritative dated source for the particular claim.
Active recall: What three labels should accompany a district population or crop-output figure?
