According to data compiled from Indian Express and other public sources, the approximate community-wise composition of Tamil Nadu’s population is as follows:
Vanniyars: 15%
Thevars (Mukkulathor): 12%
Scheduled Castes (SC): 20%
Scheduled Tribes (ST): 1.1%
Gounders (Kongu Vellala): 7%
Nadars: 6%
Brahmins: 3%
Christians: 6%
Muslims: 5%
Others: 4%
The reliability of any exit poll depends not just on sample size, but on how well that sample reflects the underlying population.
The Axis My India exit poll raises concerns on this front. From the data presented, it is unclear whether the “actual” figures refer to the composition of the sample or the real population. Regardless of interpretation, the sampling appears significantly skewed.
For instance, Brahmins constitute roughly 3% of the population, yet the poll samples them at around 9%. This is a substantial overrepresentation.
At the same time, communities such as Vanniyars (15%) and Thevars (12%) appear to be underrepresented in the sample, at roughly 7% and 2% respectively.
Such imbalances call into question the representativeness of the survey and, by extension, the reliability of its conclusions. If key demographic groups are not proportionally reflected, the resulting projections can be materially distorted.
What is equally surprising is the lack of scrutiny in public discourse. These discrepancies went largely unchallenged in televised debates, raising concerns about either a gap in analytical rigor or a tendency to prioritize sensational narratives over methodological soundness.
