Conurbation

Timelapse (1984-2018) of conurbation of the San Juan–Bayamón–Caguas metropolitan area

Forming a continuous conurbation on the northeastern coastal plain of the main island of Puerto Rico, the San Juan metropolitan area (Spanish: área metropolitana de San Juan), also simply known as the área metro (metro area), is the urban core and greater area of the San Juan–Bayamón–Caguas metropolitan area (MSA). This highly urbanized, sprawling zone is concentrated in the capital municipality of San Juan, and the surrounding municipalities of Bayamón, Carolina, Guaynabo, Trujillo Alto, and Cataño. Occasionally, the suburb of Levittown in the municipality of Toa Baja is included within the urban core, which is also commonly referred to as the área metropolitana de Puerto Rico (Puerto Rico metropolitan area), as it is the primary urban region in the archipelago and island. However, along with Aguadilla, Arecibo, Guayama, Mayagüez, and Ponce, it is only one of six metropolitan areas in Puerto Rico.[7]

Municipalities

Outside urban core

The region outside the San Juan metropolitan area, the conurbation and greater area of the San Juan–Bayamón–Caguas metropolitan area (MSA), is made up of 34 municipalities, each containing small urban zones, of which the most populous is located in the principal city of Caguas on the Caguas Valley in eastern-central Puerto Rico. These urbanized, densely populated commercial and residential zones usually concentrate around the downtown area and administrative center of the municipality, which is categorized as a barrio and known as a pueblo.

The San Juan–Bayamón–Caguas metropolitan area (MSA) varies in topography. While municipalities along the coastline have flat, low-lying terrain, most municipalities are located on elevated, hilly and mountainous terrain.

Conurbation

Comprising San Juan, Bayamón, Carolina, Guaynabo, Trujillo Alto, and Cataño, the conurbation or urban core of the San Juan metropolitan area is generally on the eastern part of the northern coastal plain of the main island of Puerto Rico. However, of the six municipalities within the urban area, only Cataño is completely situated on the coastal plain. In contrast, only the northern parts of San Juan, Bayamón, Carolina, Guaynabo, and Trujillo Alto are on the coastal plain, as the southern parts of Bayamón and Guayabo are on the hilly terrain of the Northern Karst Belt, and those of Carolina and Trujillo Alto are on the mountainous terrain of the Sierra de Luquillo. Less populated and restricted by rugged topography, these outer areas are mostly rural.

Outside urban core

Roughly covering the eastern half of the main island of Puerto Rico, the topography of the 34 municipalities outside the urban core of the San Juan metropolitan area varies between the eastern and southern coastal plains, the Caguas Valley, the Yabucoa Valley, the North Karst Belt, and the Cordillera Central, Sierra de Cayey, and Sierra de Luquillo mountain subranges.

Aside from an urbanized, densely populated downtown area and administrative center, categorized as a barrio and known as a pueblo, and concentrated urbanized residential areas with large populations, these municipalities are mostly rural, particularly those furtherest way, in distance and elevation, from the inner urban core around the capital, San Juan. Generally, low-lying areas along or near the shoreline in coastal municipalities, like those found in Vega Baja and Humacao, are greatly more urbanized and populated than inland, karstic, and mountainous areas, especially in elevated and interior municipalities like Orocovis, which is strictly rural and sparsely populated.
