Equivalents to Sun Belt growth in other countries?

[pikachu]

What areas of other countries (particularly industrialized ones since developing country megacities seem like the most obvious answer) have been seeing the type of multi-decade double-digit % population growth that’s happening in American Sun Belt cities? The first one that comes to mind to is Calgary, but I’m not sure how common this is overall.

[Skill and Chance]

There isn't really much room for new late 20th century cities in the other fully industrialized countries, so it's pretty unique.  In addition to Calgary, Perth in Australia would seem to qualify.

Not another country but Columbus Ohio is very much a sun belt city by growth patterns and annexation lines.

The most obvious example would be Mexico's mass tourism-oriented states, Quintana Roo and Baja California Sur, which were very sparsely developed and populated before the organization and planning of mass tourism infrastructure beginning in the 1970s.

Quintana Roo:
1970: 88,150
1980: 225,985
1990: 493,277
1995: 703,536
2000: 874,963
2005: 1,135,309
2010: 1,325,578
2015: 1,501,562
2020: 1,857,985

Within Quintana Roo, Playa del Carmen (Solidaridad municipality) basically grew from a tiny fishing hamlet as recently as the late 1980s into the state's second most important (and still rapidly growing) municipality: in 1990 it had a population of 3,098 (as a mainland locality part of the insular municipality of Cozumel), while in 2020 the municipality's population was 333,800.

Cancún, which is the biggest part of Benito Juárez municipality, went from a population of 37,190 in 1980 to 911,503 in 2020.

BCS's population has increased from 128,019 in 1970 to 317,764 in 1990 and 798,447 in 2020. Los Cabos municipality has grown from 43,920 in 1990 to 351,111 in 2020, making it the largest municipality ahead of La Paz, the state capital.

In the 2020 census, QRoo still had the fastest growing population of any state. It also stands out by its demographics: a very large young-ish working-age population (25-44) with very few seniors, a majority (51.6%) of the population born in another Mexican state and the highest economically active population (68.5% of 12+). This is because basically QRoo grew from basically nothing into a mass tourism-dominated state, attracting economically active migrants from other parts of Mexico to work in the tourism industry (which is the largest industry, of course).

Just the city of Shenzhen alone makes the sunbelt look pathetic.
