Gibraltar

Gibraltar's fertility rate of 1.89 is below the standard replacement level (2.1). Despite being relatively high compared to many other Western European nations, this rate suggests that, without immigration, the population would eventually decline, a common demographic challenge in developed economies.

As a highly developed and entirely urbanized territory, Gibraltar has achieved 100% access to electricity for its population. This is a key indicator of advanced infrastructure and reliable public utility services, typical of high-income European microstates.

Due to its small size and dense urbanization, Gibraltar reports 0.000% forest area. While the Rock itself has significant natural vegetation, it is not classified as 'forest' under standard international definitions, highlighting the environmental constraints of such a compact territory.

Gibraltar boasts an extremely high life expectancy of 83.55 years. This figure places it among the top countries globally, suggesting excellent public health infrastructure, high standards of living, and quality healthcare access, comparable to nations like Japan or Switzerland.
