I recently had this discussion on the US demographic thread about what would happen to the US urban hierarchy once the population decline kicked in. Some posts for context:
After those comments I updated my Polish tables and I found this "future US" I envisioned right there now. Poland and their main metro areas (using more broad definitions):
POLAND
2002: 38,230,080
2011: 38,511,824 --- +0.7%
2021: 38,036,118 --- -1.2%
Warsaw
2002: 2,745,602
2011: 2,884,076 --- +5.0%
2021: 3,238,202 -- +12.3%
Katowice
2002: 2,604,971
2011: 2,490,911 --- -4.4%
2021: 2,329,394 --- -6.5%
Gdansk
2002: 1,184,875
2011: 1,245,970 --- +5.2%
2021: 1,353,475 --- +8.6%
Krakow
2002: 1,098,764
2011: 1,131,298 --- +3.0%
2021: 1,236,313 --- +9.3%
Lodz
2002: 1,131,777
2011: 1,081,110 --- -4.5%
2021: 1,032,013 --- -4.5%
Wroclaw
2002: 860,924
2011: 882,678 --- +2.5%
2021: 993,182 -- +12.5%
Poznan
2002: 845,315
2011: 886,811 --- +4.9%
2021: 978,512 -- +10.3%
Lublin
2002: 565,911
2011: 569,160 --- +0.6%
2021: 566,953 --- -0.4%
Szczecin
2002: 475,029
2011: 481,478 --- +1.4%
2021: 479,159 --- -0.5%
Bydgoszcz
2002: 461,958
2011: 470,285 --- +1.8%
2021: 460,202 --- -2.1%
Bialystok
2002: 429,839
2011: 436,829 --- +1.6%
2021: 448,497 --- +2.7%
At first glance it seems the comparison US and Poland is a bit unusual but observe how disperse is their urban network and how Warsaw has such a small share on total population, comparable to New York. Just multiply those numbers for 9 to get the US equivalent.
Notice how Polish population started to fall but their main metro areas actually accelerated, three of them (Warsaw, Wroclaw, Poznan) at double-digit rates and other two (Gdansk and Krakow) almost there. The only exceptions were Katowice (a collection of mid-sized cities, Ruhr-style; it's hard to get more Rust Belt than this) and Lodz, another Rust Belt type.
I started to talk about Japan, our ultimate example of a mature declining society, but it's urban hierarchy is very different of the US. Poland, on the other hand, is remarkably similar and it's illustrating perfectly what I believe will happen to the US within 15-20 years.

Let's give Poland another chance to get the spotlight. I decided to bring numbers for Japan. I usually only comment on them but the actual numbers make easier to see it. Japan provides out best and maybe the only long-term example we have, as it doesn't have immigration or emigration:
JAPAN
1995: 123,611,167
2000: 126,925,843 --- +2.7%
2010: 128,057,352 --- +0.9%
2020: 126,146,099 --- -1.5%
Very linear, smooth transiction which was expected in a closed system, only births and deaths playing a factor, negligible immigration and emigration and a fertility rate that remained very stable all over this period (between 1.25-1.45).
Now let's check several versions of Tokyo, from the most broader metro area definition (Kanto's 7 prefectures) to the 23 Tokyo special wards:
TOKYO (32,433 Km²)
1995: 123,611,167
2000: 126,925,843 --- +2.3%
2010: 128,057,352 --- +5.4%
2020: 126,146,099 --- +2.5%
TOKYO (10,994 Km²)
1995: 32,719,237
2000: 33,605,853 --- +2.7%
2010: 35,861,063 --- +6.7%
2020: 37,208,968 --- +3.8%
TOKYO (2,725 Km²)
1995: 21,157,716
2000: 21,782,065 --- +3.0%
2010: 23,760,722 --- +9.1%
2020: 25,223,559 --- +6.2%
TOKYO (628 Km²)
1995: 7,967,614
2000: 8,134,688 --- +2.1%
2010: 8,945,695 -- +10.0%
2020: 9,733,276 --- +8.8%
Note that between the "biggest Tokyo" and the "smallest Tokyo" both grew slower than Japan 1995-2000. We also see that suburbanization was still happening around that time (smallest Tokyo growing slower than the bigger version of it).
After 2000, Japan's growth slows down and declines afterwards. Tokyo followed a different path and actually sped up. After 2010 a whole new phase kicks in: not only rural areas and mid-sized cities start to shrink fast, but also the far away suburbs: smaller version of Tokyo's grows much faster than the bigger ones, showing its outer suburbs are already collapse and people are not only moving to Greater Tokyo, but specifically to its inner districts, showing clearly the centripetal effect of big cities on shrinking countries.
Osaka tells a similar story, albeit with not as strong as Tokyo's magnetism which is not surprising as it's way more polycentric:
OSAKA (9,032 Km²)
1995: 18,298,344
2000: 18,549,889 --- +1.4%
2010: 18,752,230 --- +1.1%
2020: 18,603,894 --- -0.8%
OSAKA (4,583 Km²)
1995: 14,616,604
2000: 14,790,383 --- +1.2%
2010: 14,961,498 --- +1.2%
2020: 14,895,667 --- -0.4%
OSAKA (388 Km²)
1995: 4,217,817
2000: 4,177,627 --- -1.0%
2010: 4,224,900 --- +1.1%
2020: 4,349,446 --- +2.9%
OSAKA (80 Km²)
1995: 1,038,864
2000: 1,053,125 --- +1.4%
2010: 1,157,288 --- +9.9%
2020: 1,277,467 -- +10.4%
Notice how fast the "smallest Osaka" (12 wards) is growing, despite its massive density (16,000 inh./Km²). The same thing happened in the central areas of Kobe and Kyoto, but much less intense. Osaka is not only sucking up the rural areas, the outer suburbs but it's also assuming a more relevant role over its smaller peers Kobe and Kyoto.
