. In studies of urban and state income distribution, the estimation of percentile incomes within intervals reported by the Bureau of the Census has often been done under the assumption that incomes are uniformly distributed. This paper shows that income may be significantly underestimated if the assumption is applied to lower‐level percentiles in the black family income distribution. Consequently, conclusions about the level and determinants of the relative income of poor black families may be misleading.
