In this article, we compare colonias in Texas and California and evaluate the federal policy relating to them. In Texas, designated colonias are recently subdivided but unregulated housing settlements that lack infrastructure. California's designated colonias are old communities, with varying demographics, infrastructure needs, and jurisdictional authority. Because subdivisions are strongly regulated in California, we did not expect to find designated colonias there. In actuality, there are over 30.However, federal policy is based on Texas colonias, and we argue that it is too broad because it fails to distinguish between inherently distinct areas and investment needs. Paradoxically, the federal criteria for defining colonias are also too narrow. Many locally designated colonias in California do not qualify for funding because they are not close to the Mexican border or exceed the population ceiling. Ironically, some of the colonias that fail to qualify have the worst housing conditions.
