In India, the projected sex ratio for the population in 2036 is expected to see more females than males in comparison to the population as of 2011. Apart from Kerala, Karnataka, Maharashtra and Gujarat, the sex ratio is expected to increase in eighteen states of India. Of these, the lowest sex ratio is expected to be seen in the national capital region of Delhi with 899 in 2036.

In 2011, the sex ratio of the general population in India was 943 women to every one thousand men. On the other hand, the sex ratio of the elderly population in India stood at 1,033 women for every one thousand men, indicating an increase from the previous year. The sex ratio for both population types was forecasted to increase by 2031. After 2011, the sex ratio for the elderly population was estimated to be over one thousand, which indicates a higher number of elderly women than men.

This Alberta Official Statistic describes Sex Ratio, Total Dependency Ratio, and Aging Index for Alberta and Canada for two census periods, 2006 and 2011. The sex ratio is the ratio of males to females in a given population, usually expressed as the number of males for every 100 females. The sex ratio at birth in most countries is about 105 or 106 males per 100 females. After birth, sex ratios vary because of different patterns of mortality and migration for males and females within the population. Dependency ratio (age dependency ratio) is the ratio of persons in the "dependent" ages (generally under age 15 and over age 64) to those in the "economically productive" ages (15 - 64 years) in a population. The age-dependency ratio is sometimes divided into old-age dependency (the ratio of people ages 65 and older to those ages 15-64) and child-dependency (the ratio of people under age 15 to those ages 15-64) ratios. The sum of these two is the Total (age) dependency ratio. This ratio is often used as an indicator of the economic burden the productive portion of a population must carry - even though some persons defined as "dependent" are producers and some persons in the "productive" ages are economically dependent. Countries with very high birth rates usually have higher dependency ratios because of the large proportion of children in the population. The Aging Index is the ratio of persons aged 65 years and over to every 100 persons under age 15 years. It is a measure of aging of a population. The aging index shows that Alberta’s population is younger than that of Canada.

As per the last census data from 2011, the sex ratio in Mumbai city was ***. This was lower than the sex ratio of the state of Maharashtra. Child sex ratio (in the group of *** years) in the state, however, was ***. Sex ratio refers to the number of females per 1000 males.

In Japan, the population sex ratio has seen slight changes over the past decades. In 2021, the number of men was around 94.6 for every 100 women, constituting a decrease from 96.1 in 1950.

What is the sex ratio? The population sex ratio is determined by the sex ratio at birth, different mortality rates between men and women, as well as losses and gains through migration. In the absence of alteration, the sex ratio in human populations is quite constant, with only minor deviations. While the sex ratio at birth is usually 105 to 107, the population sex ratio, which refers to the total number of males for every 100 females, is often below 100. The reason for the shift mostly lies in differing lifestyles and physical constitutions of men and women. In general, women tend to be more resistant to disease throughout life, while men tend to engage in higher risk behavior or violence.

Influences and consequences
The sex ratio at birth and its possible determinants such as gestation environment, climate change, chemical pollution or socio-economic factors have long been subject to scientific research. Recently the impact of natural disasters, like the nuclear disaster in Japan in 2011, was presumed to influence the sex ratio at birth. The adult gender ratio has long been recognized as a key population-level determinant of behavior. However, there are many different or competing theories in existing literature about the social impacts of gender imbalance on topics such as violence, family stability, reproduction etc.

Evolutionary theory predicts that the spread of cytoplasmic sex ratio distorters leads to the evolution of host nuclear suppressors, although there are extremely few empirical observations of this phenomenon. Here, we demonstrate that a nuclear suppressor of a cytoplasmic male killer has spread rapidly in a population of the green lacewing Mallada desjardinsi. An M. desjardinsi population, which was strongly female-biased in 2011 because of a high prevalence of the male-killing Spiroplasma endosymbiont, had a sex ratio near parity in 2016, despite a consistent Spiroplasma prevalence. Most of the offspring derived from individuals collected in 2016 had 1 : 1 sex ratios in subsequent generations. Contrastingly, all-female or female-biased broods appeared frequently from crossings of these female offspring with males derived from a laboratory line founded by individuals collected in 2011. These results suggest near-fixation of a nuclear suppressor against male killing in 2016 and reject the notion that a non-male-killing Spiroplasma variant has spread in the population. Consistently, no significant difference was detected in mitochondrial haplotype variation between 2011 and 2016. These findings, and earlier findings in the butterfly Hypolimnas bolina in Samoa, suggest that these quick events of male recovery occur more commonly than is generally appreciated.
