US - Mexico border barriers significantly reduce illegal migration from surrounding areas as level of effort needed to immigrate increases

Types

Quotes that support the claim

Using Mexican survey data and data I collected on fence construction, I find that construction in a municipality reduces migration by 27 percent for municipality residents and 15 percent for residents of adjacent municipalities. In addition, construction reduces migration by up to 35 percent from non-border municipalities.

The deterrent effect of the fence is especially large for those who migrate from areas in which a high share of past migrants cited ease of crossing as the reason they chose a particular crossing location. These individuals presumably face particularly large cost increases if forced to use alternative crossing routes
