Bringing the two main metro areas:

Athens
1991 --- 3,532,268
2001 --- 3,823,479 ---- +8.2%
2011 --- 3,753,783 ---- -1.8%
2021 --- 3,722,544 ---- -0.8%

Thessaloniki
1991 --- 860,613
2001 --- 948,962 --- +10.3%
2011 --- 962,033 ---- +1.4%
2021 --- 959,139 ---- -0.3%

I thought Athens was growing way more, but that's not the case. Thessaloniki perfoming better for the past 30 years.

And I just realized Athens is 2nd largest metro area in the world shrinking right now. The multipolar Osaka-Kobe-Kyoto is shrinking as well.
