I think we have underestimated how easy it has been to type years like "2020," "2022," and even "2021," "2023," etc.

The physical distance between each key has been small.

Now, "2025" is a bit annoying. The "5" is too far from either the "2" or the "0".

Years like "2068" are so bad.

New article by me!

It's a common mistake to think the TFR is a prediction of the average number of children women will have over their lifetimes.

But it's not. The TFR can decline even when the eventual number of children per woman stays constant or even increases; the opposite can happen too. 🧵
A line graph compares two measures of fertility rates in Sweden over time: the total fertility rate and the completed cohort fertility rate. The total fertility rate is depicted using a red line, which shows a downward trend starting around the early 1900s, with fluctuations and a gradual decline to about 1.5 in 2022. The completed cohort fertility rate is illustrated with a blue line, with the time axis showing the women's birth year. It shows an initial decline followed by a stable fertility rate. A note at the bottom states that the completed cohort fertility rate has been shifted by 30 years to align with the respective birth years of women. The data source is the Human Fertility Database (2024) and the chart is published by Our World in Data.

Today, we have a new page on fertility data on Our World in Data!

It has lots of new charts on a wide range of measures such as parental ages at birth, teenage birth rates, twin birth rates, the use of reproductive technologies, and more.

Explore it all here: ourworldindata.org/fertility-rate
Chart showing the average age of mothers at childbirth by birth order Chart showing the share of women who have had a given number of births over time Chart showing the share of deliveries that are twins over time Chart showing the age distribution of women when they give birth, and how that has changed for women of different birth cohorts.

Spring no more: France’s shift in birth patterns
A line graph depicting the most common birth month in France from 1861 to 2022, with the horizontal axis representing months from January to December and the vertical axis indicating years. Each year shows a line indicating the month with the highest average birth rate per day, with varying colors representing different time periods. In the late 19th and early 20th centuries, lines often cluster around spring months, indicating this as the most common season for births. Disruptions during World Wars I and II are noted, as birth rates shifted temporarily. Since the late 20th century, the trend has changed, with late summer and autumn months becoming the most common for births. The data source is the Human Mortality Database (2024) and the chart is published on OurWorldinData.org, and is licensed under CC-BY by the authors, Saloni Dattani and Lucas Rodés-Guirao.

The twin baby boom
The chart titled "Share of births that are twins" displays the percentage of twin births over time, spanning from 1858 to 2021. The vertical axis represents the share of births that are twins, ranging from 0% to 2%. There are five colored lines, each representing a different country: the United States, France, Canada, Australia, and England and Wales. Throughout the years, the percentage of twin births shows a noticeable increase in each of the countries shown, particularly from the 1980s. A note on the chart indicates that delayed childbearing, alongside technologies such as IVF, has contributed to this rise in twin births. The data for this chart is sourced from the Human Multiple Births Database in 2024. The chart is credited under a Creative Commons BY license, and is published by Our World in Data.

What country has a larger population?

Sometimes the difference is of ~5%. Values according to UN WPP (2024).

I just noticed that @un.org have re-designed their WPP downloads page: population.un.org/wpp/downloads. Looks great!

One can now easily access and download earlier releases from 1998-2022

Americans are now one-third less likely to die from cancer at the same ages as Americans in 1990
How has the risk of dying from cancer changed in the United States? To understand this, we can look at national cancer death rates in the United States. The gray line shows the crude rate, which is the rate of deaths from cancer per 100,000 people. It has risen between 1950 and 1990 and has fallen slightly since then. However, cancer death rates rise sharply with age, and the age of the US population has increased since 1950, so we would expect cancer death rates to rise for that reason alone. What if we adjust for the increased age of the US population? The red line, the age-standardized rate, shows this. It shows the cancer death rate if the age structure of the US population was held constant throughout. This shows a slight rise until 1990 and then a significant decline; rates have fallen by one-third. This means Americans are now one-third less likely to die from cancer at the same ages as Americans in 1990. This comes from several factors: better screening and earlier diagnosis, medical advances in cancer treatments, and public health efforts to reduce risk factors like smoking and exposure to carcinogens.

The world is awful. The world is much better. The world can be much better.

All three statements are true at the same time. Understanding this is key to solving big global problems.

We believe data & research can help us understand both the problems we face & the progress that’s possible. 🧵

Good opportunity to point out a nice OWID feature: interactive charts have dynamic social media preview cards.

If you adjust the chart parameters (add countries, change timeframe, etc.), the URL updates automatically. Share the link, and the social card shows exactly the view you customized ✨

Until 2017, the age group with the greatest number of deaths globally was those aged under five years.

This was interesting, but I can't tell if some of you are trolling.
Survey responses to the question When does human aging begin? The potential answers include gametogenesis, conception, birth, 9 years, 20 years, 30 years. Responses are widely spread except no one responded 30 years.

Today, I'll examine mortality data. This data tells the stories of wars, famines, and other disasters in the last century. It's sad to look at but necessary. I'm also happy to see that, overall, indicators have improved globally.

Few people even know about this; when people are asked in surveys how child mortality has changed the majority says it has stagnated or increased.

If you consider that many don't know about humanity's biggest achievement, then it's not surprising that many are so pessimistic about our future.
