Rio de Janeiro, Brazil

Capital City

The city's sprawling favelas, jam-packed traffic, and 5.9 million residents make Rio de Janeiro a chaotic, high-energy place to live. Over 21% of the population resides in these informal settlements, where bureaucracy and infrastructure are chronic headaches. Severe weather like storms and flooding also wreak havoc, with the city's tropical climate producing scorching summers that can feel unbearable. However, Rio's natural beauty, vibrant culture, and tourism-fueled economy make it an enticing destination for young, adventurous expats willing to navigate its quirks.
