Total population of Irish offshore islands

The number of people living on Irish offshore islands decreased dramatically during the Irish famine and the period following it. Since then the trend on most islands has been a decreasing population until the 1950s and 1960s, during which many islands were forcibly evacuated by the Irish Government as continuous bad weather meant that islanders were unable to travel to the mainland for several consecutive months. Of the remaining islands that were not evacuated, many of their populations have continued to dwindle ever since, with some seeing stabilisation or even a slight increase in population during and after the Celtic Tiger.

The chart below shows the total number of people living on Irish islands throughout the years.
