The Glasgow Tenements and Slum Crisis

Glasgow's housing conditions in this period are unusually well documented by the standards of 19th- and early 20th-century British social history: the city's Medical Officer of Health produced detailed annual reports, and national and local census returns recorded room occupancy by household. This gives a firmer evidentiary basis than for many historical claims in this series. Where this article is more cautious is in comparative claims — "worst in Europe" is a common and broadly defensible characterisation given the scale of UK overcrowding statistics, but rigorous like-for-like comparison with continental European cities using comparable period data is harder to pin down, and some of the claim's popularity reflects its usefulness as civic shorthand rather than a precise ranking.

Scale and scope

Glasgow's 19th-century population explosion — driven by the Industrial Revolution's demand for labour in shipbuilding, engineering, and textiles — was not matched by housing supply. The city's characteristic tenement form, four or five storeys of stone-built flats arranged around a close and back court, was itself not the problem; it was the subdivision of individual flats into single rooms ("single ends") that produced extreme densities. By the time of the 1911 census, a substantial share of Glasgow's population lived at a density of more than two persons per room, a rate higher than any other city in Britain and among the highest recorded in industrialised Europe at the time.

Conditions in districts such as the Gorbals, Cowcaddens, and Townhead became a byword for urban deprivation. Multiple families often shared a single water closet on a stair landing. Overcrowding, poor ventilation, and inadequate sanitation combined to produce persistently high rates of tuberculosis and other infectious disease; Glasgow's Medical Officer of Health reports from the period record mortality rates in the poorest districts markedly above the city average and above comparable English industrial cities.

Causes

The roots of the crisis lie in the mismatch between Glasgow's explosive industrial growth and the pace of housing construction, compounded by a private rented-housing market with little incentive to invest in maintenance or reduce density, since rents were charged by room rather than by dwelling. Landownership was often fragmented and absentee, and building regulation in the early-to-mid 19th century was weak. The result was a private market that profited from subdivision rather than being penalised for it.

Public health thinking in Victorian Britain increasingly identified housing density itself — not just sanitation — as a driver of disease, and Glasgow's municipal authorities were, by UK standards, relatively proactive: the Corporation gained slum-clearance powers as early as 1866, well before equivalent legislation existed for most of Britain. But the scale of the problem consistently outran the pace of intervention until well into the 20th century, with clearance frequently displacing residents into equally overcrowded housing elsewhere in the city rather than resolving the shortage.

Policy response and slum clearance

Scotland's response unfolded in overlapping waves. The 1919 Housing Act, passed amid fears of post-war social unrest (reinforced by the 1915 Glasgow rent strikes and the radical politics of "Red Clydeside"), committed central government funding to council housing for the first time, producing early estates such as Knightswood. Clearance accelerated in the 1930s, then resumed after the Second World War at a much larger scale.

From the late 1950s, Glasgow Corporation designated Comprehensive Development Areas that bulldozed large sections of the inner city, including most of the historic Gorbals, and rehoused residents either in new high-rise blocks within the city or in large peripheral estates — Easterhouse, Drumchapel, Castlemilk, and Pollok — built on the city's outskirts, and in new towns such as East Kilbride and Cumbernauld built specifically to absorb "overspill" population (see "The New Towns Experiment"). High-rise construction was pursued partly because it allowed high housing density on cleared sites without reproducing tenement-style subdivision.

Outlook and legacy

The clearance programme solved the immediate crisis of extreme overcrowding but created new, longer-running problems. Many peripheral estates were built without adequate shops, transport links, or amenities, and some of Glasgow's worst-recorded deprivation statistics in the late 20th century were found in precisely these clearance-era estates rather than the surviving tenement districts — a pattern cited in later research on Glasgow's "excess mortality" (see "The Glasgow Effect"). High-rise blocks, intended as a modern solution, frequently suffered from poor construction quality, maintenance failures, and social isolation, and a large proportion were demolished within a few decades of being built.

From the 1970s onward, housing policy shifted decisively away from wholesale demolition toward tenement rehabilitation: surviving sandstone tenements were increasingly renovated rather than cleared, a reversal that preserved much of what today defines Glasgow's streetscape and is often cited as a rare case of planners learning from the failures of comprehensive redevelopment.

Everyday life in the tenement slums

Contemporary accounts and later oral-history projects give texture to the statistics. Families of six or more sharing a single room meant beds doubling as daytime seating, children sleeping in shifts, and little space for the sick to be isolated during the frequent outbreaks of infectious disease that overcrowding encouraged. The "back court" behind each tenement block — intended in better-off districts as a shared garden or drying green — in the poorest areas often became a dumping ground for ash and refuse, adding to the sanitary burden that already-stretched shared toilets could not resolve. Washing, cooking, and sleeping all occurred within the same single room in a "single end," with water frequently carried from a shared tap on the stair rather than piped directly into each flat.

Social reformers and municipal officials visiting these districts in the late 19th and early 20th centuries repeatedly singled out children's health as the starkest indicator of the crisis: infant mortality rates in the worst tenement districts ran well above the city average, and rickets, caused partly by poor diet and limited sunlight exposure in densely built, poorly lit closes, was common enough to be considered almost unremarkable by contemporary observers. These conditions fed directly into the political pressure that eventually produced the 1919 Housing Act and the clearance programmes that followed.

Why Scotland Built Upwards, and What It Cost

The urban historian Richard Rodger, in the Oxford Handbook of Modern Scottish History (2012), explains the tenement as a product of Scottish law and finance. In 1818 a House of Lords judgement by Lord Eldon required all restrictions on a property's use to be written into its feu charter. Combined with feuing and sub-feuing, in which land was granted in return for a permanent annual payment, this made it profitable to pile flats "storey upon storey" on each plot. The tenement, Rodger writes, was "a brilliant device that unlocked sums from small savers for assured returns". The downside was cost: land, legal and building costs were higher in Scotland, while real wages were lower and poor relief less generous, so Scots' wages bought less living space than English ones.

The results were measured carefully by the early twentieth century. In 1911, 8.7 per cent of Scotland's urban population lived in one-room houses and 39.2 per cent in two rooms, against 7.1 per cent of all English housing in one and two-room houses combined. On the English Registrar General's definition, 55.7 per cent of Glaswegians were overcrowded, along with 48.2 per cent in Dundee, 37.8 per cent in Aberdeen and 32.6 per cent in Edinburgh. Before 1914, death rates in one-room Glasgow flats were double those in four-room flats, and infant mortality four times higher. In 1915, 62 per cent of Glasgow residents in two-room flats shared a toilet. A study of 72,000 Glasgow schoolchildren concluded that living in a small house harmed health. The city's first medical officers of health, William Gairdner in Glasgow (1863–72) and Henry Littlejohn in Edinburgh (1862–1908), led the slow improvement in water, drainage and inspection.

Public housing then changed the city. About 70 per cent of all interwar housing in Scotland was built by local authorities, and Glasgow built 50,277 council houses between 1919 and 1939 on peripheral estates such as Riddrie and Kennyhill. Rodger notes that these estates lacked the social networks of the old central districts: casual work, pawnbrokers and corner-shop credit, and nearby family. Meanwhile, as Richard Finlay notes, rent control made old tenements uneconomic for landlords, and about 12 per cent of Scotland's housing stock was simply abandoned between the wars. Yet the historian Ewen Cameron points out that in 1944, after a generation of effort, 23 per cent of Scottish housing was still overcrowded and 44 per cent had only one or two rooms, against 3.8 and 4.6 per cent in England and Wales.

After 1945 the scale of intervention grew. Patrick Abercrombie's Clyde Valley Regional Plan of 1946 proposed moving 500,000 tenement dwellers: half to new estates within a green belt and half to new towns. East Kilbride was designated in 1946 against Glasgow's wishes. Glasgow Corporation pursued its own plan to demolish 172,000 unfit houses, 58 per cent of its stock, and built schemes such as Pollok, Drumchapel and Easterhouse. Rodger notes that flats were allocated using guidelines that included sectarian quotas, and that the higher rents of new-town and Scottish Special Housing Association houses filtered skilled workers out of the city. From the early 1950s to the mid-1970s 25,000–40,000 new houses a year were built in Scotland, most of them public. By 1981, 54.6 per cent of Scottish housing was publicly rented, against 26 per cent in England. Then, Cameron notes, came one of the fastest reversals anywhere: after Right to Buy, owner occupation rose from 35 per cent to 62 per cent between 1979 and 1999.

Glasgow's doctor: James Burn Russell

established Glasgow's response to its slums was led by a doctor. After part-time work by the Sanitary Committee's chairman John Ure and the physician William Tennant Gairdner, James Burn Russell became the city's first full-time Medical Officer of Health in 1872 and served for more than a quarter of a century. He gathered statistics to show what overcrowding did, writing bitterly that "we choke and hustle each other out of existence", and he described single-room homes in his paper "Life in One Room". The city's ticketing system let his department fix the maximum number of people allowed to sleep in a small house or room.

shared Over Russell's career the city's crude death rate fell from about twenty-nine to about twenty-one per thousand, according to figures cited by the historian Helen Dingwall, even as the population grew. Dingwall notes that clean water from Loch Katrine, opened in 1859, better nutrition and better control of infectious disease all played a part, so the fall cannot be credited to one man. Glasgow's hospitals had struggled to keep up: two wards of the Royal Infirmary became fever wards in 1819, and a separate fever hospital opened in 1829.

Food, milk and the poor, 1918–24

established Russell's successor, Archibald Kerr Chalmers, was Medical Officer of Health for some 26 years until 1925. The historian John Burnett, in a 1997 paper published in Order and Disorder (2000), shows how Chalmers's department dealt with hunger in the slums after the First World War. Chalmers wrote in 1920 that poverty, bad housing and poor food were "sectors in a vicious circle", and he consistently blamed environment rather than the ignorance of mothers. Feeding the poor was split between three bodies: the two parish councils (poor relief), the education authority (schoolchildren) and the Corporation (expectant and nursing mothers and children under five). A 1923 suggestion that they co-operate came to nothing.

established When the Ministry of Food raised the price of milk in the winter of 1919–20, consumption in the poorest districts, such as Mile End, fell by a third. A welfare nurse in the Calton reported that the very poor gave infants tea with toast soaked in it, and that porridge made with milk had been given up. During the unemployment of 1921–22 and the miners' strike, the Corporation paid for meals for necessitous mothers and children, spending £133,221 in the year to June 1922; in March 1922 it was feeding 10,166 mothers and their children. Chalmers designed the menus to supply energy, protein and fat: mince, steak pie, broth, lentil soup and milk puddings.

established In June 1922 two Glasgow University researchers, Annabel Tully and Elizabeth Urie, studied twelve labouring families, 97 people in all. Their diet was built on bread, often cheap burnt or misshapen "end loaves", with margarine instead of butter, almost no milk and no fruit, even though oranges were cheap. Energy intake per man had fallen from about 2,500 to 2,200 calories a day in a year, and the weight of boys and girls in poor families fell by 7.5 and 7 per cent between 1919–21 and 1923.

established The city's milk carried tuberculosis. In 1923 Glasgow learned that Ayrshire, which supplied much of its milk, had never enforced the 1899 Dairies, Cowsheds and Milk Order, which forbade mixing milk from a tuberculous cow with other milk. A proposed West of Scotland milk board to supervise quality failed because no law allowed local authorities to combine. Burnett notes that the wholesale reduction of tuberculous milk did not begin until the 1930s. Meat was little better: the city's Veterinary Officer, Alexander Trotter, complained in August 1919 that 94 of 949 sides of beef sent through Birkenhead by the Ministry of Food were completely unfit to eat.

• In 1922 Glasgow Corporation's meals for poor mothers and children ran on a weekly menu: mince, steak pie, vegetable broth, lentil soup, and sago or Creamola pudding.
• Glaswegians called the sulphur dioxide used to make old meat look fresh "Madam Rachel", after a notorious seller of beauty treatments who claimed to restore youth.
• Glasgow's "ticketed houses" carried a metal plate stating how many people were legally allowed to sleep there.
• In 1915, 62 per cent of Glaswegians living in two-room flats shared a toilet.
• By 1981 more than half of all Scottish homes (54.6 per cent) were rented from the public sector, compared with about a quarter in England.
• The "single end" — a single room serving as living room, kitchen, and bedroom for an entire family — was the characteristic Glasgow tenement dwelling at the height of overcrowding.
• Many tenement closes had a single shared outside toilet for several households, sometimes on a half-landing shared between floors.
• The 1915 Glasgow rent strikes, led largely by working-class women protesting rent increases exploiting wartime labour shortages, helped push the UK government toward its first public housing legislation in 1919.
• Some of Glasgow's most architecturally admired tenements today — in the West End and parts of the Southside — were never part of the slum crisis; overcrowding was concentrated in specific inner-city and East End districts, not uniform across the city's tenement stock.
• The Gorbals, now largely rebuilt, was at its mid-20th-century peak one of the most densely populated urban areas in Europe.
• Glasgow built more high-rise council housing per capita than almost any other British city in the 1960s — a policy that is now widely regarded as a planning misstep.
• Many of the tower blocks built to solve slum overcrowding were themselves demolished within 30–40 years of construction.
• Tenement renovation rather than demolition became official policy from the 1970s, directly reversing the previous half-century's clearance-first approach.

• Myth: all Glasgow tenements were slums. Overcrowding and insanitary conditions were concentrated in specific inner-city and East End districts, while tenements elsewhere (parts of the West End, for instance) housed middle-class residents throughout this period.
• Disputed: "the worst in Europe". The claim that Glasgow's slums were unambiguously the worst in Europe is widely repeated but rests on stronger UK-internal comparative data than precise cross-continental statistics.
• Disputed: post-war comprehensive redevelopment. There is genuine scholarly disagreement over whether it represented a net improvement in health and welfare or primarily relocated — rather than resolved — urban poverty, given the problems that later emerged in several clearance-era estates and tower blocks.
• Disputed at the time: the cause of ill health. Glasgow's Medical Officer of Health, A. K. Chalmers, blamed environment and poverty, while the physiologist D. Noel Paton saw the poor as feckless and, as late as 1922, rejected the idea that rickets was a deficiency disease, blaming housing and large families instead.
