This paper analyses how welfarism affects the segregative properties of endogenous jurisdiction formation, in a model where local jurisdictions produce a local public good and distribute an allowance to their households, both financed by a proportional tax based on the households' wealth. A jurisdiction is composed of all the households that live in the same place. Local wealth tax rates and the level of the allowance are determined to maximize a social welfare function. Households can "vote with their feet", which means that they can choose to move to the jurisdiction that offers the package "tax rate - amount of public good - allowance" that provides the highest utility level. The main result of this article is the proof that the maximin criterium is more segregative than the utilitarian one.
