zero population growth
C2Formal, Academic, Technical
Definition
Meaning
A demographic condition where the number of births plus immigrants equals the number of deaths plus emigrants over a given period, resulting in no net population change.
A theoretical demographic and social goal, often associated with environmental and sustainability movements, aiming for a stable population size to reduce pressure on resources. It can also refer to policies designed to achieve this state.
Linguistics
Semantic Notes
Often abbreviated as ZPG. Implies a long-term equilibrium, not just a temporary plateau. Strongly associated with 20th-century demographic theories and environmental activism.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. The term is used identically in demographic and environmental discourse in both varieties.
Connotations
In both regions, it carries connotations of sustainability, resource management, and sometimes controversial population control policies. May be viewed neutrally as a demographic term or ideologically by different groups.
Frequency
Slightly higher frequency in American English due to the historical prominence of the organization 'Zero Population Growth, Inc.' (now the Population Connection) founded in the US in 1968.

Context Usage
Business
Rarely used. May appear in long-term strategic reports concerning market size or labor force projections in aging societies.
Academic
Common in demography, sociology, environmental studies, and economics texts discussing long-term population trends and sustainability.
Everyday
Very rare. Might be encountered in news articles or documentaries about demographics or environmental issues.
Technical
Standard term in demography and population studies, with precise definitions and models (e.g., the stable population model).
Examples
By Part of Speech
verb
British English

- The model simulates what happens when a society decides to **zero population grow**.
adjective

- The **zero-population-growth** target is central to their manifesto.

Examples
By CEFR Level
- Some European countries have almost zero population growth.

Learning
Memory Aids
Mnemonic
Imagine a population counter that clicks up for every birth and down for every death. ZERO POPULATION GROWTH is when the counter stays on the same number – it has grown ZERO.
Conceptual Metaphor
POPULATION IS A LIVING ORGANISM (that can grow or stop growing). SUSTAINABILITY IS BALANCE (a scale in perfect equilibrium).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation like 'нулевой рост населения' as the primary term; the established calque is 'нулевой прирост населения'.
- Do not confuse with 'демографический спад' (demographic decline) or 'старение населения' (population aging), which are different, though related, phenomena.
Common Mistakes
- Using it to mean a temporary one-year halt in growth instead of a long-term equilibrium.
- Confusing it with 'replacement-level fertility', which is a specific birth rate that can *lead to* ZPG only in a closed population with no migration and a specific age structure.
- Misspelling as 'zero population *grow*'.

FAQ
Frequently Asked Questions
No, they are different. ZPG means no net change – the population is stable. A declining population means deaths and emigration consistently outnumber births and immigration.
Yes. Even with ZPG, the population can grow older if life expectancy increases and fertility rates remain at or below replacement level for an extended period.
Not at all. It means, on average, each person is 'replaced' by one person in the next generation. This typically translates to a fertility rate of about 2.1 children per woman in low-mortality societies.
This is a subject of significant debate among demographers, economists, and environmentalists. While some see it as essential for sustainability, others highlight potential economic challenges related to aging populations and argue for the benefits of managed, slower growth.
