| 2013 || July 11 || {{w|Population growth}} || Publication || Our World in Data publishes comprehensive resources on population growth, highlighting its profound impact throughout history. From just one billion in 1800, the global population has surged to over 8 billion today, with expectations of reaching a peak by the century's end. The platform provides extensive data, charts, and analysis on population distribution, changes over time, and future projections. Notably, population cartograms offer a unique perspective by adjusting country sizes based on population rather than landmass. This approach accurately depicts densely and sparsely populated areas, shedding light on global living conditions.<ref>{{cite web |last1=Ritchie |first1=Hannah |last2=Rodés-Guirao |first2=Lucas |last3=Mathieu |first3=Edouard |last4=Gerber |first4=Marcel |last5=Ortiz-Ospina |first5=Esteban |last6=Hasell |first6=Joe |last7=Roser |first7=Max |title=Population Growth |url=https://ourworldindata.org/population-growth |website=Our World in Data |access-date=22 March 2024 |date=11 July 2023}}</ref>

| 2013 || || {{w|Famine}} || Publication || Our World in Data publishes insights into famines, exploring their historical occurrence, causes, and mitigation strategies. A famine is defined as an acute episode of extreme hunger leading to excess mortality from starvation or related diseases. While famines have complex origins, modern industrial developments have reduced their prevalence, with political factors increasingly contributing to their occurrence. Despite advancements, famines remain a significant concern, albeit with diminished geographic scope and lower mortality rates compared to earlier eras. International aid and improved monitoring systems play crucial roles in famine prevention and mitigation, emphasizing the importance of addressing political barriers to food access.<ref>{{cite web |last1=Hasell |first1=Joe |last2=Roser |first2=Max |title=Famines |url=https://ourworldindata.org/famines |website=Our World in Data |access-date=22 March 2024 |date=28 December 2023}}</ref>

| 2013 || August 2 || || Publication || A data review authored by Max Roser explores quantitative information on violent deaths in non-state societies, drawing from archaeological and ethnographic studies. It highlights the abundance of ethnographic evidence for violent deaths in the recent past (since the late 19th century) and archaeological findings for the more distant past. The review notes the limitations of these sources, such as the inability to distinguish between homicides and deaths from warfare in some cases. Overall, it suggests that violence levels in prehistoric times and non-state societies vary widely but tend to be higher on average than in modern state societies.<ref>{{cite web |last1=Roser |first1=Max |title=Data review: ethnographic and archaeological evidence on violent deaths |url=https://ourworldindata.org/ethnographic-and-archaeological-evidence-on-violent-deaths |website=Our World in Data |access-date=22 March 2024 |date=28 December 2023}}</ref>

| 2013 || July || || Publication || Our World in Data provides comprehensive insights into terrorism, defining it as the use of violence by non-state actors to intimidate or coerce for political or ideological goals. While terrorism encompasses various tactics and targets, it remains relatively rare globally, albeit with significant variation across countries. Despite its infrequency in causing deaths compared to other factors like armed conflicts and homicides, terrorism is a significant concern worldwide. In 2019, approximately 20,000 deaths were attributed to terrorism globally, representing a rare cause of death globally but with varying incidence rates across regions.<ref>{{cite web |last1=Herre |first1=Bastian |last2=Samborska |first2=Veronika |last3=Ritchie |first3=Hannah |last4=Hasell |first4=Joe |last5=Mathieu |first5=Edouard |last6=Roser |first6=Max |title=Terrorism |url=https://ourworldindata.org/terrorism |website=Our World in Data |access-date=22 March 2024 |date=12 February 2024}}</ref>

| 2013 || December || {{w|Economic inequality}} || Publication || A publication delves into the distribution of incomes and wealth worldwide. It provides comprehensive data, visualizations, and analysis on economic inequality, revealing its high prevalence and upward trends in many countries. Despite global economic inequality being extensive and compounded by various factors like health and education disparities, the publication notes instances of inequality stabilization or decline within certain nations. Significantly, it highlights a recent decline in global inequality after centuries of increase, underscoring the potential for change through targeted policies to address inequality's impacts on societies.<ref>{{cite web |last1=Hasell |first1=Joe |last2=Arriagada |first2=Pablo |last3=Ortiz-Ospina |first3=Esteban |last4=Roser |first4=Max |title=Economic Inequality |url=https://ourworldindata.org/economic-inequality |website=Our World in Data |access-date=22 March 2024 |date=3 January 2024}}</ref>

| 2015 || July || || Publication || {{w|Max Roser}} and {{w|Hannah Ritchie}} publish an article discussing cancer, highlighting it as one of the leading causes of death globally, with approximately 10 million deaths in 2019. They describe cancer as a group of diseases characterized by the rapid multiplication of abnormal cells that can spread to nearby tissues and other parts of the body. Despite significant progress in understanding and treating cancer, global cancer deaths continue to rise due to factors such as population growth, aging, and greater progress against other causes of death. The article aims to provide an overview of global data and research on cancer, acknowledging its widespread impact and ongoing efforts to combat it. It would be last revised in March 2024.<ref>{{cite web |last1=Roser |first1=Max |last2=Ritchie |first2=Hannah |title=Cancer |url=https://ourworldindata.org/cancer |website=Our World in Data |access-date=19 March 2024 |date=12 March 2024}}</ref>

| 2016 || January || || Publication || [[w:Our World in Data|OWID]] publishes study analyzing the global [[w:Disease burden|burden of disease]], which encompasses both mortality and morbidity, and is measured using {{w|Disability Adjusted Life Years}} (DALYs). One DALY represents the loss of one year of healthy life due to premature death, disease, or disability. DALYs enable comparison of disease burden across countries, populations, and time periods. The Global Burden of Disease (GBD) study and the World Health Organization (WHO) have been measuring DALYs since 1990, providing comprehensive data on disease burden worldwide. This data, broken down by age, type of disability, disease, and country, helps assess the health of populations and guide public health interventions.<ref>{{cite web |last1=Roser |first1=Max |last2=Ritchie |first2=Hannah |last3=Spooner |first3=Fiona |title=Burden of Disease |url=https://ourworldindata.org/burden-of-disease |website=Our World in Data |access-date=21 March 2024 |date=29 February 2024}}</ref>

| 2016 || May 20 || {{w|Fertility rate}} || Publication || [[w:Our World in Data|OWID]] publishes study on fertility rate. Measured as the number of children per woman, it has undergone a substantial global decline since 1950. In pre-modern times, fertility rates were high due to high infant and child mortality rates. However, as health conditions improved, fertility rates decreased, halving from around 5 in the 1960s to about 2.4 in 2021. This decline in fertility rates can be attributed to various factors, including the empowerment of women through education, labor force participation, and enhanced rights, as well as improvements in the well-being and status of children. These societal changes have led to a significant shift in global population dynamics.<ref>{{cite web |last1=Roser |first1=Max |title=Fertility Rate |url=https://ourworldindata.org/fertility-rate |website=Our World in Data |access-date=22 March 2024 |date=12 March 2024}}</ref>

Through a prolonged global effort, including quarantine, improved hygiene, slaughter, and vaccination, rinderpest was eliminated in 2011. The development of a potent vaccine in 1960 by Walter Plowright was a crucial breakthrough. The Global Rinderpest Eradication Programme (GREP), initiated in 1994, intensified surveillance and vaccination efforts, leading to the last known case in Mauritania in 2003. This achievement, costing approximately USD 5.5 billion, marked the first successful eradication of an animal disease and averted substantial economic losses.<ref>{{cite web |last1=Ochmann |first1=Sophie |last2=Behrens |first2=Hannah |last3=Roser |first3=Max |title=How rinderpest was eradicated |url=https://ourworldindata.org/how-rinderpest-was-eradicated |website=Our World in Data |access-date=20 March 2024 |date=14 March 2024}}</ref>

However, women are at this time better represented in top income groups than they were in 2000. The discussion on economic inequality by gender delves into various aspects of the gender pay gap, its causes, and its implications. It highlights how the gap is measured differently across countries and over time, emphasizing that it captures inequality but not necessarily discrimination. Despite progress, the gap remains substantial in most countries, especially for older workers. Factors contributing to the gap include differences in human capital, job characteristics, discrimination, and societal norms. While education has played a role in narrowing the gap, disparities persist due to job-related factors and societal expectations. The analysis underscores the complexity of the gender pay gap and the need for comprehensive strategies to address it.<ref>{{cite web |last1=Hasell |first1=Joe |title=Top incomes: more women, but still very male-dominated |url=https://ourworldindata.org/top-incomes-more-women-but-still-very-male-dominated |website=ourworldindata.org |accessdate=17 June 2019}}</ref>

| 2023 || July 6 || {{w|Economic inequality}} || Publication || An article by Joe Hasell discusses the evolution of income inequality within countries over the past century. While the significant increase in inequality in the United States is well-documented, long-term data on the incomes of the richest individuals reveal diverse trajectories among countries. Thanks to research methods utilizing income tax records, researchers have gained insights into income inequality over extended periods, surpassing the limitations of household surveys. Coordinated efforts by the World Inequality Database have expanded the coverage of countries and periods, providing standardized estimates of income distribution. The analysis reveals that the early and mid-20th century witnessed dramatic declines in income inequality across many nations. However, from the 1980s onwards, inequality began to rise again in numerous high-income countries, forming a 'U-shaped' pattern over the century. For example, the US experienced substantial increases in income inequality, reaching levels similar to a century ago. Conversely, some countries, such as Japan, Sweden, Spain, France, and the Netherlands, have maintained relatively stable levels of inequality since the mid-20th century, displaying an 'L-shaped' trend. These variations underscore the influence of national institutions, politics, and policies in shaping income inequality, challenging the notion that rising inequality is solely determined by global economic forces.<ref>{{cite web |last1=Hasell |first1=Joe |last2=Roser |first2=Max |title=How has income inequality within countries evolved over the past century? |url=https://ourworldindata.org/how-has-income-inequality-within-countries-evolved-over-the-past-century |website=Our World in Data |access-date=18 March 2024 |date=2 February 2024}}</ref>

Latest revision as of 19:52, 21 March 2024

This is a timeline of Our World in Data (OWID), an online publication that presents empirical research and data on global change, in particular global living conditions.

Big picture

Time period Development summary
2011–2014 Max Roser starts working on OWID, researching on economic history and development economics, and collecting lots of empirical data.[1]
2014 ourworldindata.org launches. Since then, OWID would expand into a small team of researchers and web developers, and their reach and audience would grow.[2]
2015 OWID launches website sdg-tracker.org to track progress towards the Sustainable Development Goals.
2019 OWID becomes part of Y Combinator. About a million people visit ourworldindata.org each month, mainly though organic search traffic.[3]


Full timeline

Year Month and date (approximately) Topic Event type Details
2011 Prelude Max Roser, a German-born economist at the University of Oxford, starts working on OWID. Later, he would explain his project was the answer to his dissapointment and anger with a media and education that were not informing him and others about fundamental trends that are changing the world.[4][5]
2013 July 11 Population growth Publication Our World in Data publishes comprehensive resources on population growth, highlighting its profound impact throughout history. From just one billion in 1800, the global population has surged to over 8 billion today, with expectations of reaching a peak by the century's end. The platform provides extensive data, charts, and analysis on population distribution, changes over time, and future projections. Notably, population cartograms offer a unique perspective by adjusting country sizes based on population rather than landmass. This approach accurately depicts densely and sparsely populated areas, shedding light on global living conditions.[6]
2013 Famine Publication Our World in Data publishes insights into famines, exploring their historical occurrence, causes, and mitigation strategies. A famine is defined as an acute episode of extreme hunger leading to excess mortality from starvation or related diseases. While famines have complex origins, modern industrial developments have reduced their prevalence, with political factors increasingly contributing to their occurrence. Despite advancements, famines remain a significant concern, albeit with diminished geographic scope and lower mortality rates compared to earlier eras. International aid and improved monitoring systems play crucial roles in famine prevention and mitigation, emphasizing the importance of addressing political barriers to food access.[7]
2013 August 2 Publication A data review authored by Max Roser explores quantitative information on violent deaths in non-state societies, drawing from archaeological and ethnographic studies. It highlights the abundance of ethnographic evidence for violent deaths in the recent past (since the late 19th century) and archaeological findings for the more distant past. The review notes the limitations of these sources, such as the inability to distinguish between homicides and deaths from warfare in some cases. Overall, it suggests that violence levels in prehistoric times and non-state societies vary widely but tend to be higher on average than in modern state societies.[8]
2013 July Publication Our World in Data provides comprehensive insights into terrorism, defining it as the use of violence by non-state actors to intimidate or coerce for political or ideological goals. While terrorism encompasses various tactics and targets, it remains relatively rare globally, albeit with significant variation across countries. Despite its infrequency in causing deaths compared to other factors like armed conflicts and homicides, terrorism is a significant concern worldwide. In 2019, approximately 20,000 deaths were attributed to terrorism globally, representing a rare cause of death globally but with varying incidence rates across regions.[9]
2013 December Economic inequality Publication A publication delves into the distribution of incomes and wealth worldwide. It provides comprehensive data, visualizations, and analysis on economic inequality, revealing its high prevalence and upward trends in many countries. Despite global economic inequality being extensive and compounded by various factors like health and education disparities, the publication notes instances of inequality stabilization or decline within certain nations. Significantly, it highlights a recent decline in global inequality after centuries of increase, underscoring the potential for change through targeted policies to address inequality's impacts on societies.[10]

Plants, mainly trees, dominate life on Earth, comprising over 82% of biomass, while bacteria make up 13%. Surprisingly, despite our focus on animals, they account for only 0.4% of biomass. Livestock, however, outweighs wild mammals and birds ten-fold, comprising 4% of animal biomass compared to humans' 2.5%. This emphasizes the significant impact of human activities on shaping Earth's biosphere.[60]
2019 April 26 Publication Our World in Data publishes study on global biomass showing how life spans across the planet's three high-level habitat environments.[61]
2019 April 29 Gender pay gap Publication A study on data collected from nine countries is published showing that women are very underrepresented at the top of the income distribution. However, women are at this time better represented in top income groups than they were in 2000. The discussion on economic inequality by gender delves into various aspects of the gender pay gap, its causes, and its implications. It highlights how the gap is measured differently across countries and over time, emphasizing that it captures inequality but not necessarily discrimination. Despite progress, the gap remains substantial in most countries, especially for older workers. Factors contributing to the gap include differences in human capital, job characteristics, discrimination, and societal norms. While education has played a role in narrowing the gap, disparities persist due to job-related factors and societal expectations. The analysis underscores the complexity of the gender pay gap and the need for comprehensive strategies to address it.[62]
2019 May 6 Poverty reduction Publication Our World in Data publishes study indicating that the rate of poverty reduction around the world has slowed and that it may even stagnate. The decline in extreme poverty over recent decades is significant, but the COVID-19 pandemic has exacerbated the situation. While progress has been made in some regions, many still live in extreme poverty. Varying definitions of poverty across countries complicate measurement, but a global poverty line of $2.15 per day provides a consistent benchmark.[63][64]
2019 May 23 Population pyramid Publication An article is published discussing the age structure of populations globally, examining historical trends and future projections. It explains the concept of population pyramids and how they depict demographic changes over time. The analysis highlights the shift from young, growing populations to older, stable ones, impacting societies and economies. It discusses the median age variation across countries and how it correlates with income levels and population growth rates. The article also explores the evolution of age structures in different countries, illustrating the aging transition in higher-income nations and the youthful populations in lower-income ones. Lastly, it examines dependency ratios, emphasizing their significance for economic and social stability, and how they vary across the world.[65]
2019 June 11 Child mortality Publication An article is published discussing historical child mortality rates and the significant progress made in recent decades. Historical data from various regions and time periods indicate that around half of all children died before adulthood, with little variation globally. Despite efforts, no substantial progress was made until recent times, highlighting the challenge of combating early death. High historical mortality rates are supported by evidence of high birth rates and stagnant population growth. However, recent years have seen remarkable improvement, with global child mortality declining from around 50% to 4%.[66]
2019 June Gender ratio Publication Our World in Data publishes study analyzing gender ratio, which reflects the ratio between male and female populations, and fluctuates due to various biological, social, technological, cultural, and economic factors. This ratio impacts society, demographics, and the economy. The disparity in the number of men and women varies globally and over time, influenced by age groups and external forces. While "gender" and "sex" are often distinct, the term "gender ratio" is used interchangeably with "sex ratio" for familiarity and accessibility, although the latter is more precise as it directly reflects the data based on biological sex and is increasingly favored in academic discourse.[67]

Options to reduce food emissions include shifting to plant-based diets, reducing food waste, adopting healthy calorie consumption, and implementing best farming practices. While each option contributes to emissions reduction, combining them is essential for significant impact. Achieving these changes could lead to net negative emissions by 2050, offering a transformative shift towards a more sustainable global food system.[74]
2022 January 11 Poverty Publication In a ourworldindata.org publication, Max Roser discusses the historical perception of poverty and its evolution over the centuries. Contrary to Malthus' assertion of poverty inevitability, economic growth has demonstrated its potential to alleviate widespread poverty. Using Sweden as an example, Roser illustrates how economic progress has lifted many out of deep poverty, highlighting the role of strong growth in achieving this. However, he emphasizes that poverty remains pervasive globally, affecting 85% of the population, with high-income countries being the exception. Roser calculates that a significant increase in global economic output, coupled with reduced inequality, is necessary to substantially reduce poverty. Despite progress, Roser concludes that the fight against poverty is still in its early stages, with much work remaining to be done.[75]
2022 June 9 Poliomielitis Publication Saloni Dattani and Fiona Spooner in their article highlight the urgency of improving testing to eradicate polio worldwide. Despite significant progress, with a dramatic decline in cases from the early 1980s to less than 2,000 in 2020, challenges remain. The disruption in polio testing and reporting during the COVID-19 pandemic poses a risk of undetected cases and further spread of the virus. Cases have been rising in countries where wild poliovirus remains endemic, such as Afghanistan and Pakistan. Additionally, there's a concerning trend of cases emerging in countries previously declared free of wild poliovirus. To combat this, the world requires increased vaccination efforts and enhanced monitoring of potential outbreaks, focusing on areas where countries are falling short.[76]
2022 July 7 Dracunculiasis Publication Saloni Dattani and Fiona Spooner highlight the near eradication of guinea worm disease, from nearly a million cases in the late 1980s to just 15 cases worldwide in 2021. Achievements stem from an eradication program emphasizing water treatment, public education, and access to safe drinking water. Caused by the guinea worm parasite transmitted through contaminated water, the disease inflicts excruciating pain and debilitation. Village volunteers, alongside organizations like the US CDC and the Carter Center, play pivotal roles in distributing water filters, educating communities, and monitoring cases. Despite challenges like monitoring, new outbreaks, and conflict zones, the decline in cases offers hope for eventual eradication.[77]
2022 October 20 Influenza Publication Our World in Data reports that globally, seasonal influenza causes an average of 400,000 deaths from respiratory disease each year. Although the risk of death from influenza has declined over time due to improved sanitation, healthcare, and vaccination, it remains a significant burden worldwide. Individuals born in 1940 had approximately one-third of the risk of dying from influenza compared to those born in 1900, and those born in 1980 had a risk of half that of those born in 1940. Despite these improvements, factors such as an aging population and limited access to healthcare and sanitation contribute to the continued impact of influenza. The article explores these trends and risk factors, as well as the reasons behind large flu pandemics that have caused millions of deaths in some years.[78]
2023 July 6 Economic inequality Publication An article by Joe Hasell discusses the evolution of income inequality within countries over the past century. While the significant increase in inequality in the United States is well-documented, long-term data on the incomes of the richest individuals reveal diverse trajectories among countries. Thanks to research methods utilizing income tax records, researchers have gained insights into income inequality over extended periods, surpassing the limitations of household surveys. Coordinated efforts by the World Inequality Database have expanded the coverage of countries and periods, providing standardized estimates of income distribution. The analysis reveals that the early and mid-20th century witnessed dramatic declines in income inequality across many nations. However, from the 1980s onwards, inequality began to rise again in numerous high-income countries, forming a 'U-shaped' pattern over the century. For example, the US experienced substantial increases in income inequality, reaching levels similar to a century ago. Conversely, some countries, such as Japan, Sweden, Spain, France, and the Netherlands, have maintained relatively stable levels of inequality since the mid-20th century, displaying an 'L-shaped' trend. These variations underscore the influence of national institutions, politics, and policies in shaping income inequality, challenging the notion that rising inequality is solely determined by global economic forces.[79]
2023 July 11 Population growth Publication An article from Our World in Data delves into the crucial topic of population growth, charting humanity's journey from a fraction of today's numbers to over 8 billion individuals. Despite centuries of rapid expansion, experts anticipate a peak in global population by the century's end.
