Does the Dragon Year Really Increase Births?
Yes, in some countries and Chinese communities, births rise in Dragon years and fall in Tiger years. In Vietnam, the main evidence comes from a study by Quy-Toan Do and Tung D. Phung (2010), which found that birth cohorts in years considered auspicious were about 12% larger. This is evidence that childbearing behaviour is shaped by cultural belief, not evidence that the zodiac determines fate.
Why Is the Birth Year Believed to Matter?
Kind of knowledge: SchoolSchool's interpretation. How one school or one book reads it; other schools may read it differently. The five labelsIn East Asian thought, the birth year is one of the four pillars (year, month, day, hour) that make up a chart. The year's can chi is believed to influence personality, fortune, and compatibility among family members. Vietnamese astrology also distinguishes good years for boys from good years for girls, based on the can chi of the birth year compared with the parents' ages.
Kind of knowledge: Folk beliefFolk belief. What people believe, avoid or pass on by word of mouth, recorded as a belief, not as a checked fact. The five labelsMany families believe that having a child in a Dragon year, or a year considered auspicious by can chi, will bring luck, success, and favourable marriage and career prospects. Conversely, some years such as the Tiger year or the Goat year are considered less fortunate.
What Does Research in Vietnam Say?
Quy-Toan Do and Tung D. Phung (2010), published in the American Economic Journal: Applied Economics, analysed birth data in Vietnam and found that birth cohorts in years considered auspicious were about 12% larger than in other years. The study also found that children born in auspicious years had more years of schooling, but the authors note this may result from parents investing more in children born in auspicious years, not from the birth year itself.
Kind of knowledge: UnprovenNot enough evidence. Someone has claimed it, but no source or study is strong enough to confirm it. The five labelsIn addition, Kim Dung Hoang (2013) presented a summary at the IUSSP International Population Conference suggesting that births in 2012 rose even though the overall fertility rate fell. This is a conference report that has not been peer-reviewed, and the figures have not been fully verified, so it should be treated with caution.
East Asia: Common Pattern and Differences
Kind of knowledge: UnprovenNot enough evidence. Someone has claimed it, but no source or study is strong enough to confirm it. The five labelsDaniel M. Goodkind (1991) analysed data from Taiwan, Hong Kong, Singapore, Malaysia, and Chinese communities in the United States, finding that births rose clearly in the Dragon years 1976 and 1988. Paul S.F. Yip and colleagues (2002) also recorded a similar phenomenon in Hong Kong: births rose in Dragon years and fell in Tiger years. Daniel Goodkind (1996) showed that in Singapore, timing births to specific years increased with modernisation rather than declined.
Goodkind (1993) also found that in Taiwan in 1976, the main mechanism was adjusting the timing of marriage and childbearing, not just modern contraception. This shows that people actively arranged marriages and pregnancies so that children would be born in the desired year.
However, in mainland China, Goodkind (1991) notes that the institutional conditions of the Cultural Revolution and the one-child policy prevented birth surges in the Dragon years 1976 and 1988. Only in recent Dragon years (2000, 2012) have some new studies recorded a return of the birth increase.

How Do People Time Births?
Goodkind (1993) shows that in Taiwan, couples adjusted the timing of marriage so they could have a child in a Dragon year. Goodkind's (1991) research also recorded that marriages increased in the two years before a Dragon year. In mainland China, provincial data for 2003-2013 show that marriages rose in Tiger and Cat years (the two years immediately before a Dragon year), and births rose in the Dragon year.
What Does This Say About Belief and Behaviour?
The Dragon year effect is the clearest example of the saying "belief creates real behaviour." Belief in auspicious and inauspicious years is not just a notion; it has changed childbearing, marriage, and investment in children. The measurable change in births is evidence of the power of belief, not evidence that the zodiac determines fate.
Kind of knowledge: UnprovenNot enough evidence. Someone has claimed it, but no source or study is strong enough to confirm it. The five labelsHowever, it should be noted that evidence in Vietnam rests mainly on one study (Do and Phung 2010) and one non-peer-reviewed conference summary (Hoang 2013). There is no full analysis of the 2024 Giap Thin year in the available sources. Findings from Taiwan, Hong Kong, and Singapore cannot be directly extrapolated to Vietnamese people without research on Vietnamese people.
Conclusion
Belief in auspicious and inauspicious zodiac years has left traces in birth data in Vietnam and some East Asian countries. This is a real demographic phenomenon reflecting culturally influenced behaviour. The article does not comment on families' decisions to have children, but only presents the available research evidence.
