    The Population of Ireland from Ancient Times until the Great Famine

    The Population of Ireland from Ancient Times until the Great Famine


    Last year I attended a tour of the National Museum in Kildare St, Dublin.

    The tour guide stated that Ireland was 'underpopulated' in Ancient Times and we were quite primitive.

    I don't believe him on either count.

    I think the population of Ireland has fluctuated over the centuries due to War Famine and Disease but was generally on the up and nothing like as low as some may imagine,

    I think this is probably true for other Ancient Lands too and Historians have maybe gone a bit too far in cutting down the numbers - none more so than in Ireland.

    Anyway here goes:

    Primary Model

    9000 BC: 200 x <1.07% growth per century (pc)

    8500 BC 800

    8000 BC 1,600

    7500 BC 2,000

    7000 BC 2,800

    6500 BC 3,500

    6000 BC 4,500

    5500 BC 5500

    5000 BC 7,500

    4500 BC 9,000

    4000 BC 12,000

    3500 BC 15,000 Neolithic Migration < 1.1% pc

    3000 BC 25,000

    2500 BC 35,000

    2000 BC 45,000 Bronze Age Migration

    1500 BC 70,000

    1000 BC 100,000

    500 BC 130,000 Iron Age Migration

    1 AD 195,000 < 1.15 pc

    100 AD 225,000

    200 AD 260,000

    300 AD 295,000

    400 AD 340,000 x 1.17

    500 AD 400,000 x 1.075

    540 AD 430,000 – 15% Plague An blefed

    550 AD 365,000 x 1.1

    600 AD 400,000 x 1.12

    660 AD 450,000 – 15% Plague - An Buidhe Connail

    670 AD 385,000 x 1.045

    700 AD 405,000 x 1.2

    800 AD 485,000 x 1.12

    900 AD 625,000 x 1.15

    1000 AD 720,000 x 1.21

    1100 AD 870,000 x 1.22

    1200 AD 1,060,000 x 1.3 Anglo-Norman Immigration

    1300 AD 1,380,000 x 1.045

    1315 AD 1,445,000 – 10% Bruce Invasion + European Famine

    1320 AD 1,295,000 x 1.06

    1345 AD 1,370,000 – 15 % Black Death

    1360 AD 1,175,000 x 1.06

    1400 AD 1,245,000 x 1.17

    1500 AD 1,455,000 x 1.13

    1600 AD 1,646,000 x 1.1

    1640 AD 1,810,000 – 10 % 1641 Rising + Civil Wars

    1660 AD 1,630,000 x 1.4 Protestant Immigration

    1700 AD 2,282,000 x 1.15

    1712 AD 2,624,000 x 1.35

    1740 AD 3,542,000 – 10% The Great Frost

    1745 AD 3,200,000 x 1.22

    1770 AD 3,904,000 x 1.4

    1800 AD 5,465,000 x 1.28

    1821 AD 6,995,000 x 1.3

    1841 AD 9,094,000 x 5.2

    1845 AD 9,567,000 The Great Famine/An Gorta Mor

    It is after all speculative by nature for most of the Course of Irish History.

    Are you saying that there were 200 people living here is 9000BC, and five hundred years later there were 800?

    Nope

    I'm saying there might have been.

    These would have been micro nomadic groups whose numbers would fluctuate over time....

    I remember being told that one of the saints lives (the Life of Maedóg of Ferns perhaps), though composed quite a bit later) imagined the country buckling under an excessive population in the 6th and 7th century, with animals, fields and foodstuffs being rationed (3 plough ridges per person for instance). A former lecturer of mine postulated that this may have been a result of a post-Roman technological influx. However, the plagues created disturbed conditions that heavily reduced the population and lead to a more pastoral existence, incapable of supporting these high population numbers.

    I recall being told that the population of the county fell by a quarter during and after Cromwell's pacification.

    Is an increase in population of this magnitude feasible over a period of 75 years? Are there any other places where such an increase has been recorded?

    If these are your figures, what are you basing your assumptions on?

    Isn't this the generally accepted historical conjecture?

    sgtharper Ethiopias population went from 22 million to 82 million in the last 50 years.

    The potato and the clearance of most of the forests allowed for a massive population boom in Ireland.
