That's actually a racist causal interpretation made about the data when it was originally analyzed:

> At low to moderate levels of B, an increase in B should have a negative influence on housing value if Blacks are regarded as undesirable neighbors by Whites.

Isn't that saying that lower house prices are caused by racism?

In an incredible whitewashed way that's very familiar to anyone that lived during the Jim Crow era, yes. Note that it doesn't say that white people leave because they're intolerant of black neighbors, but paints black neighbors as undesirable.

Either way, it's a dramatic oversimplification. Black people are also significantly poorer than white people, so it's also likely that black people can only afford to move into a neighborhood as property values decrease... yet the people who collated this data chose to make a different assumption.
