Recently moved from Portland, OR, USA (pop. 653,115 (2018)) to Oslo, Norway (pop. 681,067 (2019)). Not sure if it is considered a "big city", but both Oslo and Portland are the biggest cities in their respective state/country. The lifestyle, transportation, and work/life balance in Oslo is much better when compared to Portland, and for that my family and I have no plans to leave anytime soon.
