Vietnam has simply handed the 100 million mark and its inhabitants continues to develop. How a ways? What is going to the rustic’s inhabitants appear to be the next day to come? Allow us to hint the demographic evolution of Vietnam and examine it with the ones of alternative Asian international locations to spot Vietnamese specificities.
Vietnam’s inhabitants will achieve 100 million in 2023. The rustic had lower than part (46 million) fifty years in the past, in 1976, when it used to be reunified because the Socialist Republic of Vietnam, and handiest one-sixth (16 million) 100 years in the past, in 1926 (Determine 1).

In step with United International locations moderate projections, the inhabitants is anticipated to keep growing and may just achieve a top of 110 million in the midst of the twenty first century, earlier than declining to 92 million in 2100. This state of affairs assumes that fertility, estimated at a mean of one.9 youngsters consistent with girl in 2023, will fall to one.21 youngsters consistent with girl.
How did the inhabitants of Vietnam achieve 100 million? Why will have to expansion prevent quickly? And what is going to the rustic’s inhabitants appear to be the next day to come?
Enlargement is related to demographic transition
The numerous build up within the inhabitants of Vietnam within the twentieth century and the start of the twenty first century is said to the demographic transition. As far and wide on the earth, mortality has fallen, particularly amongst youngsters, leading to extra births than deaths. Inhabitants expansion peaked at greater than 3% consistent with 12 months within the mid-Fifties and has been declining 12 months by way of 12 months since then, because of declining fertility.
In 2023, Vietnamese ladies will give delivery to a mean of one.9 youngsters, as already discussed, as an alternative of 6 youngsters within the Nineteen Sixties and early Seventies. Determine 2 lets in us to check the evolution of fertility in Vietnam with the evolution in 3 different East and Southeast Asian international locations: China, South Korea and Thailand.

80 years in the past, North Vietnamese government, involved concerning the speedy inhabitants expansion on the time, and in need of to gradual it down, carried out a delivery keep an eye on coverage. In 1963, the federal government first restricted a circle of relatives to a few youngsters, environment the usual at two or 3 youngsters 5 to 6 years aside.
The coverage changed into extra restrictive in 1988: the rule of thumb then changed into “one or two children” consistent with couple.
It refers to households dwelling in towns or densely populated spaces (business zones, rural areas of the Purple River Delta and Mekong Delta or the plains of coastal provinces).
The coverage, however, is much less restrictive against minority ethnic teams in deficient, remoted and carefully populated areas; she permits them to have 3 youngsters.
Did delivery keep an eye on insurance policies play a task?
Is the one- or two-child coverage answerable for Vietnam’s declining birthrate? The query is usually raised for all international locations of the South, particularly the ones in Asia, whose governments have all sought to restrict births when populations have higher impulsively and fertility has fallen sharply. That is the case for South Korea, China and Thailand, the place the decline used to be previous and sooner in those international locations than in Vietnam, and fertility reached even decrease ranges in 2023 – particularly 0.7 youngsters consistent with girl, 1.0 and 1.2 (Determine 2).
The Chinese language executive, as an example, had sought to restrict births for the reason that mid-Fifties, nevertheless it used to be no longer till the early Seventies that this coverage used to be showed after which reinforced, significantly in 1979 with the one-child coverage.
In Thailand, fertility declined concurrently in China, and simply as briefly. However the coverage used to be no longer coercive: it consisted, from the Seventies, of incentive measures, such because the liberalization of abortion and sterilization, and monetary help for training and the home agricultural financial system for {couples} restricted to 2 youngsters.
In South Korea, a speedy decline in fertility passed off a couple of years previous, with measures to advertise birth control and sterilization, but additionally with out coercive measures.
Vietnam’s delivery keep an eye on coverage used to be on the finish between the ones of China and South Korea and Thailand, combining coercion as the primary (with a one- or two-child coverage) and incentives.
As for the position those insurance policies performed, it’s tricky to measure. If within the 70s and 80s of the Seventies and Eighties in China and Thailand fertility declined so briefly, it’s basically as a result of at the moment households in those international locations sought after to have fewer youngsters – as far and wide when schooling advances and dwelling prerequisites support.
Converting path: when the state seeks to restore the delivery fee
Involved concerning the speedy ageing of the inhabitants (see the age pyramids in Determine 3), the Vietnamese executive step by step comfortable the one-to-two-child coverage within the overdue 2010s, then definitively deserted it in 2025 and now advocates a two-child circle of relatives.
As in different spaces, Vietnam has adopted China on this flip, the latter abolishing the one-child coverage in 2015 and introducing a three-child coverage in 2021 – it seems that to no impact, China’s fertility hasn’t ever been so low.

The percentage of boys amongst newborns has higher for the reason that 2000s in Vietnam, attaining 114 boys consistent with 100 women in the second one part of the 2010s (Determine 4). The similar form of expansion used to be seen 20 years previous in South Korea and China, the pioneer international locations on this box.

The rise within the intercourse ratio at delivery in those international locations stems from a robust need to have a minimum of one boy and the selective abortion of women to reach this. Extra exactly, the phenomenon is the results of a mix of 3 phenomena: the relief of circle of relatives dimension, the will for a boy at any price and the unfold of ultrasound.
However no longer all Asian international locations are affected; Thailand, as an example, by no means used to be. In India, this phenomenon has advanced handiest within the north of the rustic. The similar is correct in Vietnam, the place the north is extra affected than the south, with specifically prime intercourse ratios at delivery within the Purple River Delta and mountainous areas of the north (Determine 5).
This north-south distinction is said to cultural variations. The Purple River Delta, within the north, used to be occupied by way of China for greater than 1000 years, and this area within the nation is maximum marked by way of Chinese language affect and Confucian traditions. In this sort of area, boys are continuously most popular, as it’s as much as them to perpetuate the circle of relatives lineage and the obligation of filial piety manifested thru ancestor worship.
However, the Mekong Delta, to the south, used to be a part of the Khmer Empire for a number of centuries and is culturally with regards to Cambodia and Thailand.

The gender imbalance at delivery has been declining in recent times, and the intercourse ratio would possibly ultimately go back to a regular stage, as in South Korea. Alternatively, generations of Vietnamese youngsters wherein boys are overrepresented have already been born. Those boys chance struggling lifelong penalties, particularly after they achieve mating age: women, a minority, will haven’t any issue discovering a mate, whilst probably the most boys will stay and not using a mate.
As for the demographic outlook, they’ve to take this into consideration: the primary affected generations, the ones born within the mid-2000s, are if truth be told attaining childbearing age. Ladies, who’re few in quantity, will give delivery to few youngsters in overall, no longer sufficient to interchange their technology: from 105 boys to 100 women, 2.1 youngsters are already wanted on moderate consistent with girl to verify alternative; with 113 boys consistent with 100 women, as in the second one part of the 2010s, 2.2 is wanted.
Vietnam’s inhabitants expansion would possibly gradual sooner than up to now idea given the decline in fertility on my own. Demographic ageing would boost up, as is already the case in South Korea and China, international locations that pioneered intercourse variety, the place it used to be advanced 20 years earlier than Vietnam.
It is still noticed whether or not Vietnam will practice the similar trail as its neighbors relating to the evolution of its fertility. After a decline from the Seventies to the Nineties, the fertility fee seems to have roughly stabilized at about 2 youngsters consistent with girl since 2000. Will it stay at this stage, or will it fall to a lot decrease ranges, as is now being seen in two huge areas within the south (the Southeast and the Mekong Delta, China) and in South Korea?
Those international locations, actually, have up to now surpassed Vietnam in fertility tendencies. Within the coming years, Vietnam may just achieve even decrease ranges than lately if this nation follows its neighbors.
