Types of International Borders along the U.S.-Mexico Border

Abstract

Based on the review of the literature in political geography and international relations, and field work on international borders conducted over the last 40 years, I classified international borders into three major types as used by nation-states around the world: open, controlled, and fortified. In addition, fortified borders come in four sub-types: fenced, fenced and walled, walled, and militarized borders. The U.S.-Mexico border is used to illustrate how the changing geo-political circumstances between the U.S. and Mexico have resulted in the expression of each of the seven border types along this international border.

Definitions
Boundaries
differentiate places from each other, e.g., Roman Catholic areas from Lutheran ones in the United States; Alpine from Mediterranean climates in Europe; or cities from surrounding rural areas. Boundaries lack nation-state enforcements.

Borders
separate places from each other, creating  barriers between places, and are established and maintained by nation-state enforcements.  In their earliest forms, borders were the edges of highly organized political empires; later, they became the expressions of centrally-organized nation-states.  In all cases, the police power of states were/are critical to the creation and maintenance of borders. Throughout history, borders ranged from controlled but otherwise open to restricted to highly fortified and even militarized and, thus borders effectively close off areas in one way or another. Regardless of which types of borders, borders are exclusionary, whereas boundaries fundamentally only differentiate.
