There is no definitive answer to this question as different people have different opinions on what constitutes a "safe" place to live. Some factors that could be considered include crime rates, access to medical care and schools, and overall quality of life.
One place that could be considered relatively safe is Montego Bay. This city has a lower crime rate than some other parts of Jamaica, and it also has good infrastructure and amenities. There are several hospitals in the area, as well as private schools and universities. Additionally, Montego Bay is a popular tourist destination, so there is always a strong police presence in the city center.
Another option for those looking for a safe place to live in Jamaica is Kingston. The capital city has a higher crime rate than Montego Bay, but it also has more resources available such as hospitals, schools, and shopping centers. There is also a larger police force in Kingston which can help deter crime. However, it should be noted that many areas of Kingston can be quite dangerous if you are not familiar with the area or do not have someone local to show you around safely.
