In port cities that had lots of similar immigrants during the 1800’s, you can often tell what neighborhood someone is from by their accent. NYC (and other East Coast cities to a lesser extent) and New Orleans have some overlap because they happened to be the biggest port cities at the time and some neighborhoods had similar demographics. (Obviously, both cities have unique accents where demographics were different but there’s a lot of overlap due to that time period.)
The “neutral American accent” is supposedly originally from the Kansas, Nebraska, Iowa part of the Midwest, apparently by an accident of history. Walter Cronkite (a popular news reader as national TV broadcasts became ubiquitous) was from Kansas. Other national TV personalities happened to be from the area and it basically became the “TV” accent.
There were different historical reasons for it but it’s sort of like how “BBC English” became the accent people consider the default in England and Beijing Mandarin became “standard” Mandarin instead of Shanghainese. It’s just who was on TV/radio when media went national.
