current mood: starving but there is a plan and I’ll be eating in <5 minutes.

am i hungppy?

we act like nothing happened after dreaming intense shit.

today i had a nightmare, where i was on a plane and we crashed. I somehow survived, but the whole experience was very intense. It felt so real.

I then woke up and went to work, as usual lol. come on

ah, nice!
guess who introduced me to raycast months ago! loving it a bit more now

at least some custom workarounds for now: discussions.apple.com/thread/25079...

I'm probably not using the proper positioning of my hands, though I try...

anyway, there should be some system shortcut to type the current year.

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.

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.

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. 🧵

mostly gpt (4) because i have a work subscription; but tried others and they all work pretty much the same for me.

use it to debug, improve code, ask questions about pokemon, some research questions sometimes too :3

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.

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.

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.

Spring no more: France’s shift in birth patterns

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).

Sankey chart showing that most people who leave their home country stay on the same continent, rather than moving to a new one.

For most people, international migration means crossing a nearby border, not an ocean

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

i'm surprised that nowadays people still buy things made with fur. It just does not make sense.

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.

A chart in three parts showing data on child mortality to make the points that "The world is awful. The world is much better. The world can be much better. All three statements are true at the same time."

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 ✨

Traditional catalan masia in rural area, in the province of Lleida

Spent a night in a rural all-vegan hotel. Can’t ask for more! In Lleida province; a must if you are around Barcelona 😊

a bit of demography, conflict, data and engineering work here 👷‍♂️

there is no need

Life Expectancy People are living longer across the world, but large differences remain. Explore global data on life expectancy and how it has changed over time.

More on life expectancy: ourworldindata.org/life-expecta...

*Note*: Period life expectancy assumes that the age-specific death rates observed this year will remain constant for a newborn's entire life. Example: The death rate for 50-year-olds today is assumed to be the same rate this year's newborns will face when they turn 50

This highlights the horrific destruction wrought by Pol Pot's regime, which systematically persecuted and killed Cambodian citizens.

Pol Pot died in his sleep of a heart attack at home (while under house arrest) in 1998.

The life expectancy in Cambodia in the mid-1970s dropped to almost 11 years

and then there's Our World in Data.

That's more like a katana, which is constantly sharpened, cleaned, and even perfumed... by several people.

software projects are like knives. you have to sharpen them now and then, otherwise you can’t use them after a while.

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