Which State Has The Highest IQ In India? Data, Factors & Surprising Rankings

Bihar, Kerala, Maharashtra, Karnataka — everyone has an opinion about which state is the “brainiest” in India. Family arguments, message board battles, even the odd school quiz… the question just won’t die. But what does it mean to be the “smartest” state, anyway? And who’s actually wearing that invisible crown in 2025? Here’s where raw numbers, cultural quirks, migration patterns, and comparing apples to oranges all collide.

The Science (and Myth) of Measuring IQ in India

People love to throw around IQ scores like they’re handed out along with birth certificates. But IQ isn’t a magical number that captures someone’s full intelligence. It’s a score from tests designed to capture things like problem-solving, math skills, and pattern recognition. In India, with its maze of mother tongues and school systems, standardizing IQ testing is a challenge. Some studies use data from school exams, others use selective IQ testing from elite schools, and some even crunch numbers from international Olympiads.

For context, let’s talk about a study that made some noise: the “India IQ by State” chart by the now-defunct website ‘World Population Review’ claimed to rank states based on average IQ scores. Never heard of it? You’re not alone. The site based a lot of data on global surveys rather than sweeping, official Indian testing. That makes it fun for heated WhatsApp debates, but not quite gospel.

The big challenge? Not every Indian child gets the same education. Huge gaps exist between government and private schools, urban and rural areas, plus the North-South divide in investment and outcomes. And when a paper quotes “average IQ of Kerala is 115,” it rarely explains whether this means urban residents, English-medium students, or the entire state from Kasargod to Trivandrum.

Bottom line: no truly national, scientifically representative IQ survey has ever been completed across every Indian state. But some, like Kerala, do consistently stand out thanks to results in education-based assessments, literacy rates, and international Olympiad wins. Take the 2023 National Achievement Survey: Kerala, Delhi, and Chandigarh topped the test scores in math and science in grades VIII and X. Does that mean they’d come out on top in a formal IQ contest? Maybe. But IQ, as a raw number, doesn’t tell the whole story.

Top States: Solid Data and Controversial Rankings

If you forced me to name the “winner,” I’d say Kerala. Not because of a secret IQ test, but because numbers don’t lie about its education system:

• Kerala has a literacy rate of 96.2% (2022), the highest in India, according to the National Statistical Office.
• The state also sends more students per capita to engineering and medical schools than any other part of the country.
• Keralites routinely crack IAS, NEET, and JEE exams at high rates, and punch above their weight internationally too.

Delhi and Chandigarh, with their access to top schools and resources, also pull strong numbers. But here’s where the plot thickens: some recent surveys place Karnataka and Tamil Nadu right at the top for average IQ scores. Why? These southern states invest in STEM education, have high urbanization, and host tech hubs like Bengaluru and Chennai. As a result, school kids in Bengaluru regularly wipe the floor at math Olympiads—not just nationally but globally.

Here’s a look at some figures that have made headlines (source: National Achievement Survey, Olympiad results, State Boards):

Notice something? Kerala leads in literacy, but Karnataka boasts the most Math Olympiad medals, while Delhi shines in test scores. IQ, as you can see, isn’t just a single “district results day.” It’s a relay race of different metrics and hidden factors. Worth mentioning: Northeast states like Mizoram and Sikkim, often ignored in big headlines, knock it out of the park on state board results and English competence, despite lacking a tech hub or a giant private school culture.

What Shapes IQ and Intelligence in Indian States?

Why does Kerala do so well? One reason: universal access to early childhood education. In Kerala, the anganwadis (government-run daycares) aren’t just nominal—they actually reach every village. Women’s literacy and empowerment help too. Keralite families tend to prioritize reading, math, and after-school work. Contrast this with UP or Bihar, where huge swathes of the rural population still miss out on basic schooling, let alone math clubs or Olympiad coaching.

There’s also the influence of migration. Tamil Nadu, for example, sees a sizable chunk of its brightest kids head to bigger cities—Bengaluru, Mumbai, Delhi—for jobs and college, inflating the “brain drain” stats. Kerala is famous for sending its smart workforce overseas, especially to the Gulf, where skilled Malayalis hold down finance, engineering, and medical roles. This soft “export” of intelligence sometimes skews perceptions of which state actually has the most brainpower at home.

Then you have the language question. A large proportion of IQ and aptitude tests in India are administered in English, naturally favoring regions where English-medium schools are more common. That’s why states like Maharashtra and Karnataka, with massive metros packed with elite schools, produce stellar test scores by national and international standards. Rural Rajasthan or Chhattisgarh, despite having talent, see their kids stumble on test day thanks to language or missing exposure, not “raw” thinking skills.

Another overlooked point: nutrition and childhood health. A UNICEF report from 2022 flagged persistent problems with undernutrition and anemia in states like Jharkhand, Bihar, and UP. It’s no stretch to connect lack of early nutrition with lower cognitive development. Meanwhile, Kerala’s aggressive public health programs have fostered growth and health, giving kids a fair shot in school and beyond. So, IQ isn’t just about being born smart—it’s also about growing up in an environment where you can use that smarts.

Beyond the Numbers: Why State IQ Rankings Can Mislead

If the smartest kid in Delhi moves to Bangalore for university, who gets to claim their IQ points? When a family from Bihar puts everything they’ve got into sending one child to study medicine in Kerala, which state should get the credit for her genius? This is one of the big problems with “IQ by state” questions—it doesn’t capture the movement of minds, resources, or even shifting cultures.

The variables pile up. Urban-rural gaps, family wealth, school infrastructure, English access, exam pattern familiarity, and even parental job stability—all shape how a state does in education and test results. Add in local cultural attitudes towards schoolwork (think: Kerala’s fierce academic competition or Punjab’s focus on sports and army careers), and the picture gets messy fast.

Some experts urge caution. Formal IQ testing, especially the type used in Western studies, often fails to pick up on the practical street smarts, multi-language skills, and problem solving that shape everyday Indian life. For example, a kid in Mizoram who juggles three tongues and navigates bad roads just to reach school gets zero points for “grit” on the Stanford-Binet scale. Is that fair?

So if you’re still itching to settle the “highest IQ” debate at your next get-together, here’s a tip: start with data (kerala, karnataka, tamil nadu—these states consistently finish strong), but don’t ignore the stories behind the stats. Watch out for shifting migration, unsung stars from the Northeast, or UP’s underdog toppers who conquer despite the odds. IQ might be one snapshot of intelligence, but India’s smartest states have stories that can’t be mapped by numbers alone. And that’s what makes the question—and its many answers—so endlessly fascinating.
