How the American life changed from 1995 to 2026 is wild. More concerts, more exercise, more video games. Fewer books, less church, not staying at work longer (I guess you leave on time and continue work at home?). Source: buff.ly/QkmYfkv

The share of US Americans who hosted friends or family at their home at least monthly has declined by 71 percent in the last 50 years. Other activities declined too. This week invite a friend or two over for dinner. The next day recover from the socialising by reading a book. Source: buff.ly/7GaA1ZS

Across the globe, people increasingly say social media is harming democracy. In rich countries this opinion is more common than in poor countries. Source: buff.ly/Hg2ArGl

The chart shows 2.87 Manhattans ($2.89T GDP, 4.7M people) match Africa's economic output (1.5B people). Criticisms: it uses nominal GDP not PPP, ignores Manhattan's 1.6M daily commuters, and counts global corporate revenue booked in NYC. Still a stark contrast.

So much history in a single map. Even the "no data" part tells a story of westward expansion. A cool dataviz worth studying for a bit. Also, it must be hard finding foreign born folks in Alabama.

The spread of the Industrial Revolution across Europe. While a map like this will be able to exactly capture a momentous historical development, it is immensely helpful in understanding the geographic spread and reading local history in context. Source: buff.ly/3qR4rUs

If cost of living goes up while confidence into the future of your country and your earning potential go down, this map is the result. Sure more flows into lower fertility rates but these factors are huge.

Jupiter’s Great Red Spot is a storm bigger than Earth that has been raging for centuries. Astronomers have observed this enormous vortex continuously since at least the 1800s - likely much longer. One hell of a weather system.

I believe that a lot of the anger in the US population is rooted in these two charts. How and where this anger is channelled to determines the future of the nation. Different groups offer different solutions, different paths. What solution will win out in the long-run is still undecided.

Every glaciated region on the planet lost ice for four years in a row now. From 2023–2025 alone, glaciers lost around 1,400 gigatonnes of ice, equivalent to roughly 560 million Olympic swimming pools (the official weird measure for anything water related). Source: bit.ly/WMOStateofWa...

For the first time since at least 1982, deaths now outnumber births in reliably Republican counties across America. This demographic shift may already be reshaping US voting patterns. bit.ly/4hpvwUK
