The world made remarkable progress in child survival in the past three decades, and millions of children have better survival chances than in 1990—1 in 26 children died before reaching age five in 2021, compared to 1 in 11 in 1990. Moreover, progress in reducing child mortality rates has been accelerated in the 2000s period compared with the 1990s, with the annual rate of reduction in the global under-five mortality rate increasing from 1.8 per cent in 1990s to 4.0 per cent for 2000-2009 and 2.7 per cent for 2010-2021.

Under-five mortality

The under-five mortality rate refers to the probability a newborn would die before reaching exactly 5 years of age, expressed per 1,000 live births. In 2021, 5.0 million children under 5 years of age died. Globally, infectious diseases, including pneumonia, diarrhoea and malaria, remain a leading cause of under-five deaths, along with preterm birth and intrapartum-related complications.

The global under-five mortality rate declined by 59 per cent, from 93 deaths per 1,000 live births in 1990 to 38 in 2021. Despite this considerable progress, improving child survival remains a matter of urgent concern. In 2021 alone, roughly 13,800 under-five deaths occurred every day, an intolerably high number of largely preventable child deaths.

Documentation — version 11

This page describes how Gapminder has combined data from multiple sources into one long coherent dataset with Child mortality under age 5, for all countries for all years between 1800 to 2100.

SUMMARY DOCUMENTATION OF V11

Sources

— 1800 to 1950: Gapminder v7 (In some cases this is also used for years after 1950, see below.) This was compiled and documented by Klara Johansson and Mattias Lindgren from many sources but mainly based on www.mortality.org and the series of books called International Historical Statistics by Brian R Mitchell, which often have historic estimates of Infant mortality rate which were converted to Child mortality through regression. See detailed documentation of v7 below.

— 1950 to 2016: UNIGME, is a data collaboration project between UNICEF, WHO, UN Population Division and the World Bank. They released new estimates of child mortality for countries and a global estimate on September 19, 2019, and the data is available at www.childmortality.org. In this dataset, 70% of all countries have estimates between 1970 and 2018, while roughly half the countries also reach back to 1960 and 17% reach back to 1950.

— 1950 to 2100: UN POP, World Population Prospects 2019 provides annual data for Child mortality rate for all countries in the annually interpolated demographic indicators, called WPP2019_INT_F01_ANNUAL_DEMOGRAPHIC_INDICATORS.xlsx, accessed on January 12, 2020.

The best climate news you may not have heard about

Excerpt:

A treaty adopted 35 years ago and meant to solve an entirely different problem is also protecting the climate. And with bipartisan support from the Senate and President Joe Biden’s Oct. 26 signature, the U.S. became the world’s 139th nation to adopt a key amendment to that agreement — the first time the U.S. has joined a legally binding global measure specifically to combat climate change.

Global warming was on the back burner in 1985 when scientists from the British Antarctic Survey found a gaping hole in the planet’s stratospheric ozone layer. A natural feature of the atmosphere, the ozone layer is located between about 10 to 25 miles above Earth’s surface. It shields the planet from the sun’s ultraviolet radiation, which is harmful in large doses to our skin and to myriad other aspects of plant and animal life.

Researchers rapidly pinned down the cause of the ozone destruction: chlorofluorocarbons, known as CFCs, which are chemicals used as refrigerants and to manufacture aerosol sprays and other materials. CFCs had been recognized for years as a threat to the ozone layer, but the ozone hole found in the mid-1980s was far worse than anything expected by that point.

By 1987, diplomats had crafted a treaty known as the Montreal Protocol to fix the problem. It was an immense success, ratified by every member state of the United Nations.

There was a major catch, though.

Both CFCs and their leading replacements – hydrofluorocarbons, or HFCs – trap heat in the atmosphere, causing global warming.

….

Enter the Kigali Amendment.

Adopted at a United Nations meeting held in the Rwanda capital in October 2016, it uses a variety of policy approaches to throttle back on both the production and consumption of HFCs. The amendment has put the world on track to eliminate more than 80% of HFCs by midcentury.

One reason the Kigali Amendment passed the Senate with bipartisan support (69-27, including 21 of the chamber’s 50 Republicans) is that national action on HFCs along the lines of Kigali was already in gear. The pandemic stimulus bill of late 2020 specified an 85% cut in HFC production by 2030. Many lawmakers, especially those from states with major chemical manufacturing, had recognized that cutting HFCs made sense. For one thing, nations that have not ratified the amendment cannot trade HFCs with those that have.
