Ireland Population Pyramid 2006
Ireland in 2006
As of 2006, Ireland counted 4,268,778 inhabitants. Over the previous ten years the population grew by 17.3%, up from 3,638,509 in 1996.
The median age was 33.4 years, and for every 100 people of working age (15–64) there were 29.7 children under 15 and 15.8 people aged 65 or over. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
