OK, from someone that was born in the West Palm Beach area.
These are the bad areas:
Tamarind Avenue north of Banyan (avoid this by all means!)
Also Riviera Beach by US 1 (but much better than it was in the 1980s- early 90s)
OK so PBA is on Olive Avenue (US 1 North). This area is if you go north to Banyan. Now make a left. And THEN make a right on Tamarind. You will see what I mean. But I still think this area was even worse when I was a little kid. In fact if you take US 1 past Palm Beach Lakes, the area is not very good until you go another 5 miles after Park Avenue in Lake Park. In fact, it is quite bad. But it was definitely worse before the mid 90s.
This one area is probably why WPB is about ranked #7 by most dangerous cities. But it is not really dangerous. No, it is not Baltimore by any stretch of the imagination. But then you have the two wealthiest areas. Now Donald Trump's mansion mar-a-lago is if you go south to Southern Boulevard go over the bridge to Palm Beach, and right where A1A turns is his mansion which goes from the intracoastal to the ocean. And Tiger Woods has a home in Jupiter Island about 15 miles north. So there are great extremes in class and socioeconomics status here. That is the sad thing. And very few good jobs at all besides people in the medical or law field. High cost of living and many people besides the rich struggling. In many of the suburbs you see HUGE homes and it is the lifestyle of the rich, but then in other areas such as sectinos of Lake Worth and the area I just described you think that you are in a poorer area of the Caribbean.
