Population Density in Ireland from 1990 to 2021

Ireland's population density rose steadily from 51 people per square kilometer in 1990 to 73 in 2021, indicating moderate urbanization and population growth over the past three decades. The late 1990s and early 2000s saw an economic boom, known as the Celtic Tiger, which attracted a significant workforce to cities like Dublin, Cork, and Galway. This period marked a notable population increase in urban centers as job opportunities expanded, pushing up density in these areas.

From 2010 onward, Ireland’s density continued a gradual rise as economic recovery brought steady immigration and population growth. Dublin remains a primary contributor to higher density levels due to its role as an economic and cultural hub, while other cities and towns also contribute modestly. By 2021, Ireland’s population density reflects balanced growth, supported by a robust economy and managed urban expansion, keeping density increase steady but sustainable.
