List of countries by infant and under-five mortality rates

List of countries by infant and under-five mortality rates is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of countries by infant and under-five mortality rates rather than just read about it. In short: The under-five mortality rate (U5MR) is the number of deaths of infants and children under five years old per 1000 live births. The under-five mortality rate for the world is 39 deaths according to the World Bank and the World Health Organization (WHO). 5.3 million children under age five died in 2018, 14,722 every day.

Reference excerpt

The under-five mortality rate (U5MR) is the number of deaths of infants and children under five years old per 1000 live births. The under-five mortality rate for the world is 39 deaths according to the World Bank and the World Health Organization (WHO). 5.3 million children under age five died in 2018, 14,722 every day. The infant mortality rate is the number of deaths of infants under one year old per 1,000 live births. This rate is often used as an indicator of the level of health in a country. The infant mortality rate of the world in 2019 was 28 according to the United Nations and the projected estimate for 2020 was 30.8 according to the CIA World Factbook. Note that due to differences in reporting, these numbers may not be comparable across countries. The WHO recommendation is that all children who show signs of life should be recorded as live births. In many countries this standard is not followed, artificially lowering their infant mortality rates relative to countries which follow those standards.

Under-five mortality from the World Bank The World Bank has 2024 data by country. World average of Under-five mortality rate is 36.7 per 1,000 live births, according to 2023 estimates. Asterisk (*) indicates "Health in LOCATION" links.

Worked examples

Example 1 — a first encounter with List of countries by infant and under-five mortality rates

Start with the simplest possible case. Write down what List of countries by infant and under-five mortality rates claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of countries by infant and under-five mortality rates before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of countries by infant and under-five mortality rates ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of countries by infant and under-five mortality rates

In research: List of countries by infant and under-five mortality rates appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of countries by infant and under-five mortality rates in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of countries by infant and under-five mortality rates is common in secondary-school and first-year university syllabi. It links to neighbouring topics Death-related lists, Death of children, Demographic lists, so understanding it makes those chapters shorter.
In everyday life: Look for List of countries by infant and under-five mortality rates outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
