That had decreased to 2.31 million by 2019. They are now closer to the estimates from the World Health Organization, although there are still big differences. However, both put the death from indoor air pollution in the millions. And, despite the uncertainties in the data, the trend in declining deaths is accepted and two independent experts we contacted said they do not have any reason to doubt the data we are using in this question.\n\n[1]  [IHME Global Burden of Disease Study 2019 via Our World In Data](https:\u002F\u002Fourworldindata.org\u002Findoor-air-pollution)  \n[2]  [WHO - Household air pollution and health](https:\u002F\u002Fwww.who.int\u002Fnews-room\u002Ffact-sheets\u002Fdetail\u002Fhousehold-air-pollution-and-health)  ","Indoor air pollution, caused by people cooking food and heating their homes using wood, coal, waste or dung, is still one of the main causes of deaths in the world. But since 1990, the number of deaths from diseases caused by indoor air pollution has dropped from an estimated 4 million to just over 2 million. \n\nThat drop is even more impressive when you consider that the world’s population increased by more than a third during that time!\n\nThe poorer a country is, the more likely people are to be using these unclean fuels. As the world has become richer in the past 30 years, one of the benefits is that people can afford stoves and forms of heating that don’t damage their health.\n\nHowever, there are still more than two billion people who rely on open fires to cook and that needs to change – but the progress that has already been made should give us hope that it is possible. \n\n### Why is it a problem that people are wrong about this?\nIt can make them skeptical that it is possible to stop preventable deaths in poor countries. The data shows that huge improvements can be made with something as seemingly simple as a change of cooking fuel.\n\n### Why are people wrong about this?\nPeople are becoming more aware about pollution in big cities and how it is affecting people’s health and probably assume that there is a growing problem with every kind of pollution.\n\n### Can I trust this fact?\nYes, but there are uncertainties in the data. We use the IHME’s data for this question. Estimates for deaths due to indoor air pollution increased by a lot between the IHME’s 2017 and 2019 Global Burden of Disease Studies. There are also differences between the IHME’s estimates and those from the World Health Organization, but both put the number of deaths from indoor air pollution each in the millions. Despite the uncertainties in the data, the trend in declining deaths is accepted and two independent experts we contacted said they do not have any reason to doubt the data we are using in this question.\n\n### Discover more\nRead more about indoor air pollution at [Our World In Data](https:\u002F\u002Fourworldindata.org\u002Findoor-air-pollution).
