Mexico's population is heavily concentrated in the central and southern parts of the country, leaving vast northern territories sparsely inhabited. The least densely populated regions are the Northern States and the Northwestern States, characterized by arid climates, rugged terrain, and limited water resources.
This expansive region borders the United States and includes the following states:
The Chihuahuan Desert dominates much of this area, creating harsh living conditions with extreme temperatures and scarce rainfall. Economic activity centers on mining, maquiladoras (border factories), and limited agriculture near river valleys.
West of the Sierra Madre Occidental, this coastal and mountainous region comprises:
While Sinaloa and Nayarit have fertile coastal plains supporting agriculture (notably tomatoes, chilies, and mangoes), the interior mountains and highlands remain thinly settled. Jalisco and Aguascalientes are more developed but still have large rural expanses with low population density.
Key factors include:
Despite low density, these regions are vital to Mexico's economy, contributing significantly to mineral production, agricultural exports, and cross-border trade.
