Human Population Planning

Human population planning refers to policies and strategies implemented by governments or institutions to manage the rate of population growth. Historically known as population control, the practice has shifted in aims over time. Before the mid-twentieth century, population planning in many societies sought to increase population size to strengthen labour forces, armies and economic output. Between the 1950s and 1980s, however, fears of overpopulation, resource scarcity, environmental degradation and political instability prompted many countries to adopt measures intended to slow population growth.
In recent decades, the demographic landscape has changed once again. Declining fertility rates and ageing populations have led countries such as China, Japan, South Korea, Russia, Iran, Italy, Spain, Finland, Hungary and Estonia to introduce policies designed to boost birth rates in order to counteract workforce contraction and future economic strain. While many forms of population planning aim to improve wellbeing by expanding reproductive autonomy, others—most notably China’s former one-child and two-child policies—have involved coercive methods.

Types of Population Planning

Population planning policies can be grouped into three broad categories:

• Policies affecting overall population growth, either encouraging higher fertility or aiming to limit birth rates.
• Policies directed at altering the growth of specific population subgroups, including those defined by socioeconomic status, educational level or perceived abilities.
• Eugenic policies, which may seek either to increase the reproduction of desired groups (positive eugenics) or reduce reproduction among targeted groups (negative eugenics).

Policies that attempt to equalise fertility rates across social classes or demographic categories also fall within the broader scope of population planning.

Historical Perspectives

Ancient to Medieval Thought

Concerns about population size have appeared in philosophical, political and religious writings since antiquity. Around 300 BC, the Indian thinker Chanakya regarded population as a vital source of power and supported policies encouraging marriage and childbirth. In ancient Greece, Plato and Aristotle assessed ideal population sizes for city-states, arguing for populations large enough for defence but small enough for effective governance. Aristotle believed that excessive population growth would provoke poverty and unrest, and he controversially supported abortion and infanticide as methods of limiting numbers.
In China, Confucius and other scholars warned that unchecked growth could depress living standards. Han Fei identified a mismatch between exponential population growth and more limited food production centuries before similar ideas were articulated by Western writers. Despite such warnings, early Chinese dynasties often enacted policies encouraging marriage and fertility.
The Roman Empire introduced laws under Augustus to stimulate childbirth among citizens. These provided benefits for married couples with children and penalised those without offspring, though resistance eventually rendered many of these measures ineffective.
Christian theological traditions in medieval Europe generally supported pro-natalist views based on the biblical imperative to “be fruitful and multiply”. Nevertheless, writers such as Tertullian noted that famine, war and disease could limit population, framing these calamities as natural checks on growth. Scholars such as Ibn Khaldun later connected population change to economic cycles, associating growth with prosperity and decline with hardship.

Early Modern Developments

By the sixteenth and seventeenth centuries, European cities were expanding rapidly and debates about population size resurfaced. Thinkers such as Niccolò Machiavelli, Jean Bodin, Giovanni Botero and Richard Hakluyt examined the relationship between population growth, labour supply, economic output and social stability. Some advocated for emigration to relieve pressures of overcrowding, while others emphasised the economic benefits of a large workforce.
Exploration also revealed population management practices in other regions. In 1817, Otto von Kotzebue documented the use of infanticide in the Marshall Islands as a response to frequent famine, illustrating the global diversity of population strategies.

Population Planning in the Modern Era

Malthusian Thought

Modern population planning was profoundly shaped by the ideas of Thomas Malthus, who in 1798 argued that population grows geometrically while food supply increases arithmetically. Malthus distinguished between:

• Positive checks—disease, war, famine and disaster, which raise mortality.
• Preventative checks—delayed marriage, moral restraint, and birth control, which reduce fertility.

He believed uncontrolled population growth would produce widespread misery, particularly among the poor, and advocated for voluntary restraint as a humane solution.

Twentieth-Century Movements

The twentieth century witnessed the rise of global population planning efforts fuelled by concerns over rapid growth in developing nations. International organisations, governments and philanthropic institutions supported family planning programmes, improved access to contraception and public education about reproductive health. Scholars such as Paul R. Ehrlich warned of environmental collapse and humanitarian crises if population growth outpaced resources.
At the same time, some governments adopted coercive or interventionist policies. China’s one-child policy, introduced in 1979, is among the most significant and controversial examples, involving penalties for unauthorised births and strict reproductive regulation. Other countries implemented sterilisation programmes or incentives aimed at influencing fertility among specific groups, raising ethical and human rights concerns.

Contemporary Challenges and Shifting Priorities

While overpopulation remains a concern in parts of the world, many nations now face the opposite challenge: declining fertility, shrinking workforces and ageing populations. These trends have prompted policies aimed at increasing birth rates, including:

• financial incentives such as child allowances, housing subsidies and tax benefits;
• extended parental leave and subsidised childcare;
• programmes to promote work–life balance and gender equality in the labour market.
