Recently, several researchers have attempted to evaluate the extent to
which housing discrimination explains the continuing levels of racial
separation in U.S. metropolitan areas. They often use audit data that
show that black households are likely to experience substantial discr
imination in the housing market. A reevaluation of the statistical stu
dies of segregation suggests that the effects of discrimination are sm
aller than has been previously postulated, and direct estimates of hou
sing discrimination from surveys provide a rationale for such smaller
effects.
