Stage 1 Countries Demographic Transition Model: 2025 Explainer

Stage 1 countries in the demographic transition model are pre-industrial populations where both birth rates and death rates are very high and roughly in balance, so total population stays nearly flat for long periods. This is the model’s baseline stage — the condition in which all human societies are believed to have lived until roughly the late 18th century, when the balance first broke in Western Europe (Wikipedia — Demographic transition). Today, no country truly fits Stage 1, but a few isolated populations still show some of its features.

What Stage 1 Means

The demographic transition model is a framework describing how societies move from high birth and death rates to low ones as they develop. Stage 1 is the starting point: the pre-industrial baseline.

In this stage, birth rates are high partly because children are economic assets on farms — extra hands for planting and harvesting — and partly because many will not survive to adulthood. Death rates are equally high, driven by infectious disease, famine, poor sanitation, and limited medicine. Because the two rates sit close together, natural increase is minimal.

The model’s logic is simple arithmetic: population change equals births minus deaths. When roughly equal numbers of people are born and die each year, a society grows very slowly or not at all. Historical estimates put long-run growth rates at less than 0.05% per year from the Agricultural Revolution until the late 1700s — growth was constrained by the available food supply, since societies lacked the technology to raise output reliably.

Slow growth does not mean stability for individuals. High death rates mean frequent bereavement, and a single bad harvest can push a region into crisis. Stage 1 societies are fragile in ways that later stages are not.

Stage 1 Countries in 2025

As of 2025, there are no true Stage 1 countries. Every recognized nation has moved into at least Stage 2, where death rates have fallen while birth rates remain high, producing rapid growth (United Nations Population Division).

What remains are approximations. A few isolated communities — some remote indigenous groups, certain subsistence populations in difficult environments — have never been fully integrated into national health and economic systems and show elevated mortality alongside high fertility. Even these are not true Stage 1 cases, because almost all have some access to modern medicine, and national statistics rarely capture them separately.

It is worth distinguishing “poor” from “Stage 1.” Many low-income countries today have high birth rates, but their death rates are far below pre-industrial levels thanks to vaccines, antibiotics, and basic sanitation. That combination is Stage 2, not Stage 1.

Characteristics and Example

Stage 1 societies share a recognizable set of features, all of which reinforce one another.

• Agrarian economies. Most people work in farming or herding, and family size is tied to labor needs.
• High infant and child mortality. A large share of children die before their fifth birthday, so families bear many births to reach a desired number of surviving children.
• No family planning. Contraception is unavailable, unknown, or socially rejected; fertility is largely uncontrolled.
• Low education, especially for women. Female literacy and schooling are limited, which is strongly associated with higher fertility.
• Disease and food insecurity. Epidemics and harvest failures cause periodic mortality spikes.

The clearest Stage 1 examples are historical rather than contemporary. Pre-industrial Europe before the late 18th century fits the description well.

Imagine a village of 1,000 people where 40 babies are born each year and 38 people die. The population grows by two people — about 0.2% — but a famine year could reverse that entirely. Compare this with a Stage 2 village of the same size where births stay at 40 but deaths fall to 15: growth jumps to 25 people a year, or 2.5%. That widening gap is what turns a static population into a rapidly growing one.

Why Stage 1 Is Rare Today

The transition away from Stage 1 is one of the most consistent patterns in social science. As countries gain technology, education — particularly for women — and economic development, death rates fall first, then birth rates follow (Our World in Data).

Three forces do most of the work:

1. Healthcare. Vaccines, clean water, and antibiotics cut mortality sharply, ending the high-death half of the Stage 1 balance.
2. Development. Rising incomes and urbanization change the economics of children, shifting them from productive assets to costly investments.
3. Education. Schooling, especially for girls, delays marriage and childbearing and increases demand for smaller families.

The model is a generalization, not a law. It often fits individual countries imprecisely because social, political, and economic factors vary so much (US Census Bureau). Researchers still debate causation — whether industrialization and higher incomes drive lower fertility, or whether falling fertility helps enable industrialization, as demographer John Caldwell argued. The model also offers no clear endpoint. Stage 5, proposed by some demographers, describes societies where birth rates fall below death rates and populations shrink — the opposite problem from Stage 1, and the one facing much of the world today.

Key Takeaways

• Stage 1 is the pre-industrial baseline of the demographic transition model, defined by high birth and death rates that roughly cancel out, producing near-zero population growth.
• All human societies are believed to have been in Stage 1 until the late 18th century, when the balance first ended in Western Europe.
• No country in 2025 is truly in Stage 1; the closest approximations are small, isolated populations partly outside national health and economic systems.
• Typical features include agrarian economies, high infant mortality, no family planning, and limited female education.
• Falling death rates push societies into Stage 2, which is why high-fertility countries today are not Stage 1 examples.
• The model is a simplification that fits countries unevenly, and its Stage 1 starting point is largely historical rather than a description of the present.
