El Salvador

The infant mortality rate of 9.2 per 1,000 live births is relatively low compared to the average for countries with similar GDP per capita levels. This suggests effective public health interventions, particularly in maternal and child health, despite potential resource constraints.

74.6% of El Salvador's population lives in urban areas, a high percentage comparable to highly industrialized nations. This high urbanization rate, paired with a relatively moderate GDP per capita of $5,365, suggests significant pressure on urban infrastructure and services, possibly driven by internal migration or limited rural opportunities.

El Salvador has achieved nearly universal access to electricity, with 98.3% of the population connected. This high level of infrastructure development is a significant achievement for a developing nation and is crucial for supporting economic growth and quality of life improvements.

With a fertility rate of 1.78 children per woman, El Salvador is well below the replacement level (2.1). This indicates a rapidly aging population structure and suggests that, barring significant immigration, the country's population will begin to decline in the coming decades, a trend often seen in more developed economies.
