Summary of Sex Ratio in India

Traditionally, India has had a skewed sex ratio favoring males due to patriarchal norms and female foeticide. The sex ratio is measured as females born for every 1000 males. As per the 2011 Census, India’s sex ratio was 943 but, according to the National Family Health Survey it was improved to 1020. While India has made some progress in improving its sex ratio, there is still a significant deficit of females, especially in rural areas. There are also regional disparities with Haryana having a concerningly low ratio. The main reasons for the imbalanced sex ratio are deep-rooted patriarchal norms favoring sons, female foeticide and sex-selective abortions. This imbalance has negative consequences like delayed marriages and diminished political participation for women. Laws like Preconception and Pre-Natal Diagnostic Techniques (PCPNDT) Act of 1994 and schemes like Beti Bachao Beti Padhao aim to improve the sex ratio. Education, economic empowerment of women, stricter enforcement of laws, and raising youth awareness are crucial for achieving gender equality.

Background of Sex Ratio in India

Sex ratio in India is a contested issue. It has been skewed since ages due to the preference of male child in the patriarchal Indian society. This ratio of the number of men in a population compared to the number of women in the population is called the Sex Ratio. This ratio differs from region to region. This difference is explained due to historical reasons like preference of boys in a feudalistic society. The Indian Sex Ratio is calculated using the population's ratio of females to males, or 1000 females to 1000 males.

Introduction of Sex Ratio in India

The number of females per 1000 males is known as the sex ratio. It has been determined through studies and research that there are more men than women in the majority of countries. However, to carry out their assigned roles, society requires and expects a proportionate balance between the genders.

Males typically have a slight birth advantage, but as they get older, the differences in life expectancy causes this discrepancy to gradually even out. However, certain areas may see variations in the gender ratio due to things like traditions, cultural norms, and financial circumstances. It is important to closely monitor these statistics in order to understand population dynamics and address issues pertaining to gender.

Need to Study Sex Ratio

It is an important aspect of the human population's demographics that provides insight into the social, cultural, and economic patterns of society, including


Types of Sex Ratio: Based on the developmental stages, there are four different kinds of sex ratios:

Census 2011 Findings

National Family Health Survey 5 (NFHS-5) 2020-21 Findings

Child Sex Ratio

The ratio of females to males in the 0–6 age group is known as the child sex ratio.

Reasons for Low Sex Ratio

Despite significant development, it is seen that some prosperous regions still have poor sex ratio. This is because of various factors like son preference and nuclear families where the male heir would inherit the property. Accessibility to pre-natal sex selection is also more rapidly available in affluent areas.

Impact of Low Sex Ratio

Government Initiatives towards Improving the sex ratio


International Conventions: India has ratified Convention on Elimination of All Forms of Discrimination Against Women (CEDAW) in 1993 which mandates securing women’s rights through national laws .
