With a mayoral election coming up in New York City, some residents are considering moving elsewhere:

As the reality settles in that Zohran Mamdani — a steadfast Democratic Socialist — may soon become New York City‘s mayor, many city-dwellers are planning their escape route.

This is because the policies at the core of Mamdani’s campaign are largely unpopular with wealthy and upper-middle class New Yorkers…

‘We are absolutely seeing a correlation between Zohran Mamdani’s surprise win in the Democratic primary and an uptick in real estate interest in Westchester,’ Zach and Heather Harrison, real estate agents in the area, noted.

‘Since the summer, nearly every buyer from the city we have taken out to see homes in Westchester has mentioned the mayoral election as one of the drivers for shopping in the suburbs,’ they told Realtor.com.

Since Mamdani won the Democratic primary in June, sales going into contract in Westchester County are up 15 percent compared to the same period last year, according to The Harrison Team…

In comparison to New York City, Westchester offers more space, lower crime rates, and often lower effective taxes.

Several quick thoughts:

1. The article is vague on numbers. How many people have moved or might move? And separate from how many do move, how many would have to move for it to be meaningful as a media story or make a substantial difference in local activity?
2. We hear similar claims about political changes or taxes at the state or national level; people with resources will leave if they think they are being targeted and/or conditions are better elsewhere. I do not know if I have heard this before suggesting people will move from the city to that city’s suburbs.
3. Westchester County could be a paradigmatic suburban county in the United States. It borders New York City and it grew quickly in the early 1900s. It became a wealthy suburban setting with many houses, access to the city via highway and railroad, some green spaces and waterways, and home to major corporations. Would an influx of wealthy New York City residents feed into the character of the county or alter it at all?
4. At what point would policies or conditions need to change for most of wealthy residents of a city to leave?
