Child Health Statistics

What does it mean that 6.8% of children were wasted in 2022 while 4.2 million under 5s still died in 2021, and access gaps keep appearing from handwashing to timely postnatal care and treatment that is less likely than it should be? This page links the biggest child health risks, from pneumonia and diarrhoea to measles resurgence and immunization coverage, so you can see where prevention works and where it is falling short.

Nearly 6.8% of children worldwide were wasted in 2022, about 45 million kids, even as immunization helps prevent an estimated 1.9 million deaths each year. At the same time, huge gaps persist in the basics that keep children healthy, from safely managed drinking water to timely breastfeeding and adequate treatment when pneumonia and diarrhea strike. Let’s look at how these indicators connect, and why the picture is so uneven across preventable risks and survival chances.

Verified

Disease Burden Interpretation

The disease burden facing children remains high and closely tied to preventable infections and nutrition, with 36.7% of children aged 0 to 5 living in places with rising measles risk and around 2.3 million child deaths in 2021 attributed to unsafe WASH.

Immunization Coverage

1In 2022, an estimated 67 million children globally missed at least one dose of DTP-containing vaccine (DTP1–DTP3 missed doses), reflecting immunization system disruptions[21]

Verified

Immunization Coverage Interpretation

In 2022, 67 million children globally missed at least one DTP dose, a clear sign that immunization coverage faced serious disruptions.

Nutrition & Feeding

1In 2022, approximately 70% of households with children had access to soap and water at a handwashing facility on premises (a proxy for hand hygiene capability), improving readiness to reduce diarrheal and respiratory risks[22]

Single source

2In 2022, 45% of children under 2 years received minimum dietary diversity (including at least 4 food groups), a key indicator of adequacy of complementary feeding[23]

Verified

3In 2022, 33% of children under 2 years received at least the minimum acceptable diet, reflecting gaps in both meal frequency and diversity[24]

Verified

Nutrition & Feeding Interpretation

In 2022, while only 45% of children under 2 met minimum dietary diversity and 33% received at least the minimum acceptable diet, the Nutrition and Feeding picture is clear that most young children still fall short on meal adequacy even as 2 billion people globally remain without adequate nutrition.

Verified

4In 2020, maternal pre-pregnancy overweight/obesity affected 28% of women globally (estimated), increasing risks for birth complications that affect child health outcomes[30]

Verified

Maternal & Newborn Interpretation

Across the Maternal and Newborn category, while 74% of children aged 6 to 23 months received vitamin A in 2022, gaps in early newborn care remain substantial, with 45% lacking timely postnatal care in the first two days in 2021 and 29% not protected by early postnatal services within the first day in 2019.

Service Access

1In 2019, 60% of children with suspected pneumonia sought care, but only about 22% received care meeting recommended antibiotic treatment guidance (care-seeking vs. quality gap)[31]

Directional

2In 2020, 68% of children with diarrhea sought care, but only 39% received oral rehydration solution (consistent with persistent gaps between care-seeking and correct treatment)[32]

Verified

Service Access Interpretation

In the service access gap, children show high care-seeking but much lower receipt of recommended treatment, with suspected pneumonia rising from 60% seeking care in 2019 to only 22% getting guideline antibiotics and diarrhea in 2020 moving from 68% seeking care to just 39% receiving oral rehydration solution.
