Homeless people in Osaka City are geographically concentrated. The purpose of this paper is to empirically test the hypothesis that the geographic concentration arises from the benefits of homeless networks. A spatial regression model is estimated using data on Osaka City's homeless population by census blocks. The positive coefficient of the spatially lagged dependent variable enables us to explore how a homeless network across census blocks, outweighs a negative competition effect. The estimated results indicate that homeless networks exist in homeless societies. [ABSTRACT FROM AUTHOR]
