Cazenga, Angola

With a population of over 1 million residents crammed into just 37 square kilometers, Cazenga is Angola's most densely populated city. Residents pay steep prices for basic utilities like water, which costs the equivalent of 10 cents per 5 gallons - a significant burden when the legal minimum daily wage is just $1. Bureaucratic headaches are a persistent challenge, as the municipality is divided into three separate communes. Overall, Cazenga is a crowded, high-cost city that may only appeal to the most adventurous expats willing to navigate its complexities.
