Here’s what you’ll learn when you read this story:

  • By studying population trends and forecasting models, researchers have come to believe that nearly 15,000 U.S. cities will face noticeable depopulation by 2100.
  • Populated areas of the cities in question could experience a decline of up to 44 percent.
  • Projections call for the biggest drops in city populations to occur in the Northeast and Midwest.

Sounds like the USA needs more immigration.

The USA has plenty of immigration, they just choose to not live where all these towns are depopulating. No one can figure out why.

/S

Because it's full of maga idiots?

Two men were standing under a tree when it began to rain. One said to the other, "good thing this tree will keep us dry."

"But what happens when the treek is soaked, and it can no longer keep us dry?" Asked the second.

"Don't worry," said the first, "we're in a forest. We'll just run to another tree."

That's a bandaid fix. Everyone is depopulating except like 5 African countries which are going to enter their own negative birth rates in 15 years if they continue developing.

Im Canadian, and India crossed into negative birth rates a few years ago. The median age in India is almost 30 now

With a population of 1.45B people, India has a median age of 29.5 years which makes it the 108/196 oldest country. 24.6% of the demographic are children 0-14 years old, 68.2% are working-age people aged 15-64, and 7.15% are older population aged 65+ years

Source

What this means is

A) average age is going to go up roughly 1 year every 2 years

B) the average age in India will be roughly 38 or so in 20 years

C) their 65+ cohort increases by a huge margin

Eventually even they are too old and you're importing a demographic they desperately want to retain domestically. Same with the Phillipines and other emigrant nations.

At what point are we just colonizing other nations through immigration? When their best and brightest all leave the country to earn more in a foreign country, start a family there, and the only thing they give back is a remittance. Any kids they would have had are citizens of their new home nation and they're probably not going back (statistically the supermajority) while their home country dips into negative birth rates and having never developed industrially to support a massive cohort of elderly people.

Hilariously I could see a point where an immigrant takes any net benefit they provide in a foreign nation and use it to support their own elderly parents and grand parents in their home country. The entire planet one giant retirement home...

Correct. Our government however, thinks they need to die.
