Ireland’s population could grow to between 6 million and 7.59 million by 2065, depending on migration patterns, according to new demographic projections from the Department of Finance that underscore immigration’s critical role in the country’s future.
The “Future Forty” analysis examines potential demographic changes over four decades, modeling scenarios based on varying assumptions about migration, fertility, and mortality rates. The projections represent dramatic growth from Ireland’s current population of 5.15 million recorded in the 2022 census.
The department outlines three distinct scenarios highlighting migration’s pivotal influence on Ireland’s demographic trajectory. Under a low migration scenario, with net inward migration of 18,500 annually, the population would reach 6 million by 2065, but the labour force would begin contracting from 2041.
A central scenario assumes net migration between 35,000 and 40,000 people yearly, pushing the population to 6.77 million while sustaining labour force growth until 2047. The high migration scenario, with annual net inflows of 53,000 to 58,000 people, could see the population reach 7.59 million while maintaining workforce expansion over the same timeframe.
These projections reflect Ireland’s demographic challenges, particularly a declining fertility rate that has plummeted from 2.6 births per woman four decades ago to just 1.53 today – well below the 2.1 replacement rate needed for natural population stability.
The analysis warns that Ireland’s non-migrant labour force will decline from 2035 onward, making immigration essential to offset demographic pressures. If net migration fell to zero by 2035, “Ireland’s labour force would contract from that point onwards” with potentially “very negative” economic consequences.
Finance Minister Paschal Donohoe emphasized the far-reaching implications of demographic change, stating that population shifts will significantly impact “our labour market, the delivery of public services and the continued growth of our economy.”
The report serves as a foundation for broader departmental analysis examining how various economic and fiscal factors might affect Ireland over the next four decades, as policymakers grapple with an ageing society’s challenges.
