A sense of fullness

Here's one take: Trump, following border trip, says country is full: 'We can't do it anymore'

President Trump, fresh off a trip to the U.S. southern border, doubled-down on his message that “the country is full”

...

“The country is full. We have ... our system is full. We can't do it anymore,” Trump said

...

The president shared the same message earlier in the day at a roundtable with law enforcement and immigration officials, telling any potential migrants to “turn around” because the U.S. “can’t take you anymore.”

• U.S. population growth has fallen to 80-year lows. The country now adds approximately 900,000 fewer people each year than it did in the early 2000s.
• The last decade marks the first time in the past century that the United States has experienced low population growth and low prime working age growth on a sustained basis at the same time.
• Uneven population growth is leaving more places behind. 86% of counties now grow more slowly than the nation as a whole, up from 64% in the 1990s.
• In total, 61 million Americans live in counties with stagnant or shrinking populations and 38 million live in the 41% of U.S. counties experiencing rates of demographic decline similar to Japan’s.
• 80% of U.S. counties, home to 149 million Americans, lost prime working age adults from 2007 to 2017, and 65% will again over the next decade.
• By 2037, two-thirds of U.S. counties will contain fewer prime working age adults than they did in 1997, even though the country will add 24.1 million prime working age adults and 98.8 million people in total over that same period.
• Population decline affects communities in every state. Half of U.S. states lost prime working age adults from 2007-2017. 43% of counties in the average state lost population in that same time period, and 76% lost prime working age adults.
• Shrinking places are also aging the most rapidly. By 2027, 26% of the population in the fastest shrinking counties will be 65 and older compared to 20% nationwide.
• Population loss is hitting many places with already weak socioeconomic foundations. The share of the adult population with at least a bachelor’s degree in the bottom decile of population loss is half that in the top decile of population growth. Educational attainment in the fastest shrinking counties is on average equivalent to that of Mexico today or the United States in 1978.
• Population loss itself perpetuates economic decline. Its deleterious effects on housing markets, local government finances, productivity, and dynamism make it harder for communities to bounce back. For example, this analysis found that a 1 percentage point decline in a county’s population growth rate is associated with a 2-3 percentage point decline in its startup rate over the past decade.

Happily for me, I live in one of those areas where immigrants are welcomed; nearly everyone that I spend my waking hours with is either an immigrant or a child of an immigrant, and my part of the country is experiencing the most breathtaking growth, both cultural growth and economic growth, since the pre-Civil-War "Gold Rush" years of 1849-1850.

But I understand that other areas of the country are different.
