How do you explain the statistics that show that the sex ratio in Tribes in India is more favourable to women than the sex ratio among Scheduled Castes?

In short

The more favourable sex ratio among Scheduled Tribes reflects bride price, women's visible economic role, flexible kinship and limited access to sex selection, while Sanskritisation and north-western concentration depress it among Scheduled Castes. Census 2011 recorded 990 females per 1,000 males among STs against 945 among SCs.

Model answer

Ghissu Editorial · Verified 4 Oct 2026

Introduction
Census 2011 recorded a sex ratio of 990 among Scheduled Tribes against 945 among Scheduled Castes and 943 nationally, and child sex ratios of 957 and 933. The gap lies in social structure and region, not income alone.
Why Tribal Societies Value Daughters
•

Bride price

Tribes such as the Gonds and Santhals pay a bride price, so a daughter brings wealth instead of a dowry burden.

•

Women's economic role

Tribal women are valued earners in shifting cultivation and forest produce collection, which gives them autonomy.

•

Flexible kinship

Matrilineal Khasis and Garos, and freer divorce and widow remarriage, reduce the stigma of being a woman.

•

Limited sex selection

Remoteness and weak market reach have restricted access to ultrasound-based sex determination.

Why the Sex Ratio Among Scheduled Castes Lags
•

Sanskritisation

As M.N. Srinivas explained, castes seeking status copy upper-caste dowry, seclusion and bans on widow remarriage, which make the girl child a liability.

•

Regional concentration

SCs are concentrated in the son-preferring north-west, about a third of Punjab's population, while STs live mainly in the North-East and central India.

•

Landlessness

Mostly landless SC households rely on sons for wage income and old-age support, and clinics in the plains make sex selection easier.

Conclusion
A culture that values women's work protects daughters better than income alone. Girl-child education, delayed marriage and strict enforcement of the PCPNDT Act must keep tribal areas from losing this advantage and raise SC ratios.
