The surge of interest in this topic in 2021 was largely driven by the release of China's Seventh National Population Census data in May 2021, alongside viral social media documentation of its real-world effects. The Census Numbers
The videos trending in 2021 opened a window into deeper systemic issues that continue to reshape Chinese society:

The main reason for this imbalance is the cultural preference for sons over daughters, which is deeply rooted in Chinese tradition. In many rural areas, families rely on sons to support them financially and to carry on the family lineage. This preference, combined with the one-child policy implemented in 1979, led to a surge in sex-selective abortions and infanticide.
In traditional Chinese society, sons are viewed as essential for carrying on the family lineage, inheriting property, and providing financial support for aging parents. When the One-Child Policy restricted family sizes, the desire for a male heir intensified. chinese sex ratio video 2021
On paper, it sounds mathematical. In reality, it was a collision point between cold, hard demographic data and the warm, messy complexity of modern relationships. In 2021, the "ratio" wasn't just about numbers; it was a cultural barometer measuring the tension between traditional expectations and a new wave of romantic storytelling.
The 2021 census data exposed a profound structural deficit in the national demographic makeup:
The 2021 videos also shed light on the hyper-competitive and highly commercialized nature of modern Chinese dating, driven entirely by supply and demand. The Bride Price ( Caili )
In the crucial marriageability demographic (ages 20 to 40), there were about 17.5 million more men than women. The surge of interest in this topic in
Footage from public parks in cities like Shanghai and Beijing showed desperate parents listing their sons' credentials (income, apartment ownership, education) on umbrellas, trying to attract increasingly scarce prospective brides.
Some demographers link the surplus of young, single men to increased savings rates (to compete for brides), reduced consumption, and potential increases in violent crime.
In 2021, the Chinese Ratio was not a static formula but a contested language for desire and security. Dominant romantic storylines used it to validate pragmatic, state-aligned partnerships. Yet, emerging subcultures weaponized the ratio to highlight social inequities, proposing that the most revolutionary act in a neoliberal society might be a love story that refuses to balance the books. As China moves toward an aging, low-birthrate society, how the ratio evolves—whether toward flexibility or rigidity—will shape the next generation of romantic narratives.
Because women are in high demand, the traditional custom of caili (bride price) has skyrocketed. In rural areas, a prospective groom is often expected to provide a cash payment to the bride's family, alongside a house and a car. This has priced millions of lower-income men out of the marriage market entirely. The Rise of the "Hypergamy" Trap In many rural areas, families rely on sons
According to the 2021 National Population Census, China's sex ratio at birth stood at 111.3 boys per 100 girls, with 51.3% of the population being male and 48.7% female. This translates to a surplus of 33.3 million males, with many of these excess males likely to remain unmarried and without a female partner.

Documentaries and citizen vlogs showcased rural communities heavily populated by single men ( guanggun , or "bare branches"). These videos put a human face on the statistics, showing aging bachelors living with their parents, unable to find wives due to the migration of rural women to wealthier tier-1 cities.
Viral videos from 2021 vividly illustrated the phenomenon of Guanggun ("Bare Branches")—a term used for men destined to never marry or pass on their family name. Documentaries tracked rural villages in provinces like Hainan, Shaanxi, and Henan, where female faces were entirely absent from younger demographics. 2. The Economics of the "Bride Price" ( Caili )
