Liverpool Population by Year: 1801 to 2025

Liverpool's population tells much of the city's modern history in one set of numbers.

A historical series used by National Museums Liverpool puts the population at about 82,430 in 1801. By 1931 it had passed 846,000. Seventy years later, in 2001, it had fallen below 440,000. That long decline has since reversed, and the latest mid-year estimate for the modern Liverpool local authority is 507,915.

There is one complication worth holding onto before the numbers start. Liverpool's boundaries changed repeatedly while the city grew, so a population figure from 1801, 1901 or 1931 is not automatically measuring the same piece of land as the figure for 2025.

The short version

• Liverpool had roughly 82,000 people in 1801 in one widely used historical series.
• The population increased more than tenfold over the following 130 years.
• The historical series reaches 846,101 in 1931.
• There was no census in 1941 because of the Second World War.
• Liverpool's population fell heavily through the second half of the 20th century, reaching about 439,500 in 2001.
• Census 2011 recorded 466,415 and Census 2021 about 486,100.
• The latest mid-year estimate is 507,915.
• These figures are not all like-for-like, because Liverpool's boundaries and census definitions changed over time.

Liverpool population from 1801 to 2025

The historical figures below use the long-run population series reproduced by National Museums Liverpool from historical census material and A Vision of Britain for 1801 to 2001. The modern figures use the Census and Office for National Statistics population estimates.

The 1801 to 2001 historical series is reproduced in National Museums Liverpool material and attributed there to A Vision of Britain. Current A Vision of Britain datasets also hold alternative Liverpool reporting units, which is one reason individual figures found elsewhere can differ. The 2025 figure is an estimate rather than a census count, published through Liverpool City Council's key statistics and ONS local-authority data.

Why Liverpool population figures do not all match

Anyone researching Liverpool's historical population quickly hits an apparent problem: two reputable sources can give different figures for the same year. This is usually a geography problem rather than a mistake.

The 1901 Census is a clear example. It recorded 684,958 people within Liverpool's county borough boundaries as they stood that year. Liverpool had already been enlarged in 1895, Garston was incorporated in 1902, and applying that later boundary to the 1901 population raises the total to 702,247. The same issue appears around 1911, when the census reported 746,421 people in the City of Liverpool as constituted that year, while broader historical series produce a higher figure.

ONS makes the same point in general terms. Comparing censuses across long periods is affected by changes in geography, definitions and methods. So it would be misleading to draw a perfectly smooth line from 1801 to 2025 and imply every point represents an identical area.

The broad trend is not in question.

Liverpool grew about tenfold in the nineteenth century

At the start of the nineteenth century Liverpool was already an important port, but nothing like the city it would become. The historical series rises from 82,430 people in 1801 to 320,513 by 1851, and past 648,000 by 1881.

The growth was tied to the expanding port, warehousing, commerce, industry and large-scale migration into the city. Historic England describes nineteenth-century Liverpool as a magnet for migrants from England, Wales, Scotland and, in particular, Ireland. Rapid growth put extreme pressure on housing, especially in the courts and cellar dwellings that poorer residents lived in.

It was not spread evenly. Research into nineteenth-century Merseyside found the fastest expansion in places such as Everton, Kirkdale and Toxteth, as settlement spread beyond the older centre. Liverpool was physically becoming a much larger place at the same time as its legal boundaries were being redrawn.

The Irish Famine changed Liverpool's population

Migration from Ireland was already central to Liverpool's development, but the Great Famine of the 1840s accelerated it sharply.

Liverpool was one of the main points of arrival for people crossing the Irish Sea. Some travelled on to North America or elsewhere in Britain. Many stayed, concentrated around the dock districts and the already overcrowded parts of the town. Our history of Liverpool covers how that reshaped the city's churches, politics, music and family names.

This is why Liverpool's nineteenth-century growth cannot be read as natural increase from births. Migration was fundamental to it.

Liverpool approached its peak between the wars

Population growth carried on into the early twentieth century. The historical series rises from 711,030 in 1901 to 766,044 in 1911, 805,066 in 1921 and 846,101 in 1931. A contemporary county borough series gives an even larger 855,688 for 1931, again showing the effect of geography.

What can safely be said is that Liverpool contained well over 800,000 residents by the early 1930s. That was close to twice the population of the modern city council area.

There was no Liverpool census in 1941

The normal ten-year census would have fallen in 1941. It did not take place. No census was held in England and Wales because of the Second World War. Instead the government compiled the 1939 Register shortly after the outbreak of war, mainly for identity cards, rationing and wartime administration rather than as a normal count.

A historical Liverpool table should not present a "1941 Census population" as though one existed. The next census was taken in 1951.

Liverpool lost hundreds of thousands of residents after the war

The story changes direction sharply after the pre-war peak. By the historical series, Liverpool lost more than 400,000 residents between 1931 and 2001, a reduction of roughly 48 per cent.

Describing all of those people as simply "leaving Liverpool" misses part of what happened. Some moved only a few miles.

Kirkby shows what happened outside the boundary

Post-war housing policy deliberately moved large numbers of people out of congested inner Liverpool. Kirkby is one of the clearest examples. Liverpool Corporation bought land there for housing and industry after the war, and Kirkby's population grew from only a few thousand people to 52,207 by the 1961 Census.

A family moving from an inner Liverpool court or terrace into a new home beyond the council boundary reduced Liverpool city's recorded population, even if work, family and daily life stayed closely tied to Liverpool. The post-war fall reflects both wider economic change and the outward movement of housing and population into surrounding districts. Our piece on what was here before Liverpool ONE covers the city-centre streets that clearance removed.

The decline stopped around the turn of the century

The 2001 figure is the turning point in the modern series. Liverpool's population stood at about 439,500.

Census 2011 then recorded 466,415, an increase of nearly 27,000. Census 2021 recorded about 486,100, a further rise of 4.2 per cent. After decades in which each census confirmed further loss, Liverpool was growing again for the first time in a century.

Liverpool's population passed half a million again

The recovery has continued beyond the 2021 Census. The latest mid-year population figure for the Liverpool local authority is 507,915, which puts the city council area back above half a million residents. Liverpool City Council puts the growth over ten years at 37,962 people, or 8.1 per cent.

It is still well below the population contained within Liverpool at its early-twentieth-century peak. But comparing those figures directly, without accounting for the boundary changes, exaggerates the difference. Liverpool in 2025 is also part of a much larger continuous urban area.

Liverpool city is not Liverpool City Region

The 507,915 figure refers to the Metropolitan District of Liverpool, the area administered by Liverpool City Council. ONS identifies it as local authority code E08000012.

It should not be confused with the wider Liverpool City Region, which contains Liverpool, Knowsley, Sefton, St Helens, Wirral and Halton. Its estimated population is about 1.6 million.

That distinction explains why searches for "Liverpool population" produce figures of roughly 500,000, 900,000, 1.5 million or 1.6 million. They are often measuring different geographies rather than contradicting one another.

What Liverpool's population curve shows

The most useful way to read the numbers is in four phases.

• 1801 to the early twentieth century: fast growth as Liverpool expanded as a port, commercial centre and destination for migration.
• Early twentieth century to the 1930s: the population climbed above 800,000 and reached its peak.
• Post-war to 2001: heavy loss as housing decentralised, surrounding towns expanded and the port economy changed.
• 2001 to 2025: sustained recovery, from roughly 439,500 to just over 507,900.

Liverpool remains much smaller, by its historical series, than it was at its early-twentieth-century peak. But the direction of travel has held for more than two decades.
