Living on $2 a day is extremely challenging and generally not sustainable in most parts of the world, but some regions may offer lower costs of living that could make it more feasible. Here are a few places where the cost of living is significantly lower, though even there, $2 a day would require extreme frugality and resourcefulness:
Certain Areas in Southeast Asia: Countries like Cambodia, Vietnam, and Laos have low costs for food and accommodation. Rural areas tend to be cheaper than urban centers.
India: In some rural areas, it's possible to live on very little, especially if you rely on local markets for food and have minimal expenses.
Nicaragua: This Central American country has a low cost of living, particularly outside of tourist areas.
Bangladesh: In rural regions, the cost of living can be quite low, though access to services may be limited.
