School uniform sets sold in India per year
Cohort sizing + replacement frequency — clean and fast.
Estimate annual sales of school uniform sets in India. A textbook cohort × frequency build: how many school-goers, how many sets each per year.
Cohort
1.4B population, near-uniform age pyramid up to ~25: each year-cohort ≈ 23M. Ages 5–17 = 13 cohorts → ~300M children.
Enrolled & uniformed
Enrollment ~90%; nearly all Indian schools (government and private) mandate uniforms → ~255M uniform-wearing students.
Sets per year
Growing children outgrow + wear out: ~2 sets/yr in primary, ~1.5 in senior grades → blended ~2.
Total
255M × 2 ≈ ~500M sets a year.
How to defend it
Mention the seasonality insight: ~70% of volume sells in the June–July back-to-school window — useful if the conversation pivots to "how would a uniform maker plan capacity?" Interviewers often extend guesstimates into a mini business question; anticipate the extension.
