Depending were you want to live and what kind of climate you can still live quite cheaply all over the world.
I will name some places were you can live under $1000 a month easily, everything included.
Europe:
Malta
Poland
Ukraine
Hungary
Bucharest
Czech Repl
Probably more countries
Asia
India, a lot of places can be done for $500 and if you up that budget to a 1k you can live on the beach, like Goa.
Thailand, Chiang mai can be done for $500 a month, Koh Samui can even be done for $500 but that's pretty much only grinding and not going out at all. But rent and food can be done for $500 a month.
Same goes for Cambodia, Vietnam, Indonesia and Philippines. Lowest probably $500 and medium living $1k a month.
Th Euro countries, you can rent for 500Eur easily and if you are willing to share/ look for a better deal you can probably rent for 300-350 a month. Food is around 200 Eur, so you can live for 500-600 Eur even in EU.
