These statistics on lung disease in the UK were compiled as part of our Respiratory Health of the Nation project by teams at St George’s University of London, Nottingham University and Imperial College London.
Lung disease in the UK – big picture statistics
Numbers of people in the UK living with lung disease
Surveys of the general population suggest that approximately 12.7 million people in the UK (approximately 1 in 5) have a history of asthma, COPD or another longstanding respiratory illness. Half of these (about 6.5 million people) report taking prescribed medication for lung disease in the last year.
Estimates based on general practice records suggest that 8 million people have been diagnosed with asthma, 1.2 million with COPD, and over 150,000 with interstitial lung diseases (pulmonary fibrosis or sarcoidosis), with numbers generally similar for males and females.
From GP records, an estimated 86,000 people in the UK have ever been diagnosed with lung cancer, and over 5,000 (mainly men) have ever been diagnosed with mesothelioma.

Numbers of people in the UK who developed lung disease in 2012
Estimates based on general practice records suggest that in 2012 there were about 160,000 new cases of asthma, with numbers slightly higher among females than males, and over 110,000 people who developed COPD, with more males than females. There were about 10,000 new cases of pulmonary fibrosis and 4,500 of sarcoidosis.
According to GP statistics there are over 32,000 new cases of lung cancer and over 2,000 new cases of mesothelioma annually. However, these are likely to underestimate the true incidence of cancer, because the diagnosis may be made in hospital during terminal illness, or post-mortem.
According to cancer registration statistics, during 2011, there were 43,463 new cases of lung cancer (23,770 among males and 19,693 among females), and 2,570 new cases of mesothelioma (2,172 among males and 398 among females).

Numbers of people who die from lung disease
Lung diseases are one of the leading causes of death in the UK
During 2008-12, lung diseases were responsible for 20% of all deaths in the UK each year. In 2012, there were 114,225 deaths from lung diseases compared to 158,383 from cardiovascular diseases. However, over the 5-year period 2008–12, the proportion of deaths from cardiovascular diseases declined, whereas the proportion due to lung diseases remained constant.

Over half of the deaths from lung disease in the UK are due to lung cancer and COPD. Both conditions are strongly linked to tobacco smoking, which is also a risk factor for pneumonia, another leading cause of death.
In 2012, 6.2% of all UK deaths were due to lung cancer, 5.3% to COPD and 5.1% to pneumonia.

Children aged 0–14 years
In 2012, there were 2,435 deaths in children aged 0−14 years. Of these, only 262 were due to lung diseases and 102 to cardiovascular disease. The majority of deaths (74 per cent) were from other causes.
Of the 262 deaths from lung disease, 115 were the result of perinatal conditions (present in the time immediately before and after birth) and congenital respiratory conditions (present at birth, either inherited or caused by environmental factors).
Large numbers of deaths in this age group were caused by pneumonia (58) and acute LRTI (25).

Adults aged 15−64 years
In 2012, in people aged 15–64 years, lung diseases caused 16 per cent of all deaths among the major disease groups. Cardiovascular disease was responsible for 20 per cent, non-respiratory for 31 per cent and other causes for 33 per cent.
Of the 13,739 deaths from lung disease in this age group, lung cancer caused 8.4 per cent.
Deaths from cystic fibrosis were higher in young adults (105 deaths) compared with children (four deaths) and people over 65 (two deaths).

Adults over 65 years
In 2012, 476,510 people over the age of 65 died. Of these, 100,224 died from lung disease – the highest number among all age groups.
In people over 65, among major disease groups, lung diseases cause 21 per cent of deaths and cardiovascular disease causes 30 per cent – higher figures than for any other age group
The number of deaths from pneumonia (27,520) and COPD (27,056) were high in this age group compared with others.
There were 28,053 deaths from lung cancer among people over 65. However, the proportion of lung cancer deaths in this age group (5.9 per cent) is lower than the proportion for young adults (8.4 per cent).

Regional variation in the risk of dying from lung disease
Death rates from lung disease vary across the UK
Death rates are affected by a number of factors:
- Population structure
- Whether people live in urban or rural settings
- Standards of living
- The numbers who smoke
- Exposure through work to the causes of some lung diseases
- Air pollution levels
Relative risk of death from any lung disease, by local authority district (England, Scotland and Wales), 2008–12
Relative risk is used to compare risk in different groups of people. In medical research, all sorts of groups are compared to others to see whether belonging to one group or other puts you at greater risk of something. In this instance, relative risk has been used to see how people’s risk of dying from any lung disease varies according to where they live in England, Scotland and Wales.

Deaths from lung disease in the UK compared with other countries
To get a sense of how the picture for lung disease in the UK compares to the rest of the world, the researchers involved in the Respiratory Health of the Nation project looked at figures for respiratory disease in 99 other countries.
Figures were available for the following conditions:
They found that more than half of the deaths from lung disease in Europe, and at least a quarter of all hospital admissions for respiratory conditions, are due to diseases caused by smoking.
Strikingly, the UK is in the top 20 countries for both lung cancer and COPD deaths and admissions.
FInd out how these figures were calculated.
Burden on health services
Hospital admissions and bed-days due to lung disease
Lung diseases place a heavy burden on health services. One way of attempting to measure the scale of this burden is to calculate the number of hospital admissions and bed-days due to lung disease.
However, it should be noted that these figures are really only the tip of the iceberg. Because of the nature of conditions such as asthma and COPD, many patients are managed in the community and are never admitted to hospital because of their lung condition.
In 2011, there were 694,000 hospital admissions for lung diseases in the UK – 8 per cent of all admissions, similar to cardiovascular disease at 9 per cent.
There were 6,120,400 bed-days due to lung disease – 10 per cent of all bed-days, compared to 12 per cent for cardiovascular disease.

UK bed-days from lung diseases, 2011
In 2011, the greatest numbers of hospital admissions for a lung disease were:
- Pneumonia: 204,798
- COPD/bronchiectasis: 149,771
- Acute LRTI: 121,326
In 2011, the greatest numbers of bed-days for a lung disease were:
- Pneumonia: 2,346,324
- COPD/bronchiectasis: 1,132,827
- Acute LRTI: 792,583
In 2011 also, lung cancer was responsible for large numbers in both categories:
- Admissions: 48,540
- Bed-days: 496,207
These figures are unsurprising, given that research has shown that lung diseases associated with tobacco smoking – lung cancer and COPD – have the biggest impact on the health service.
Male and female hospital admissions and bed-days
In 2011, of the total hospital admissions for all major disease groups, at 10%, more males were admitted for a lung disease than females, at 7%.
These figures are similar to those for cardiovascular disease: 12% for males and 7% for females.
In the same year, of the total hospital admissions for all major disease groups, at 11%, there were more male bed-days for a lung disease than female bed-days, at 9%.
These figures are similar to those for cardiovascular disease: 13% for males and 11% for females.
In 2011, of the total hospital admissions for all major disease groups, figures for major individual lung diseases were:
- Pneumonia: males 2.9%, females 2.1%
- COPD: males 1.9%, females 1.5%
- Lung cancer: males 0.8%, females 0.4%
The percentages of bed-days for pneumonia were higher than the percentages of admissions though still higher in males (4.1%) than females (3.6%).
For COPD, at 1.7%, the figure is slightly higher for females than males, at 1.8%.
Asthma was responsible for 0.7% of the total hospital admissions for all major disease groups, with percentages similar for males and females.
However, at 0.4%, there were more female bed-days for asthma than for males, at 0.2%.

Age and hospital admissions and bed-days
How much people need to use health services varies very much according to age, with the very young and those over 65 generally needing them most.
Children aged 0−14 years
In 2011, of the total number of hospital admissions for all major disease groups, 9% were for lung disease in children aged 0–14 years.
In the same year, lung diseases accounted for 12% of all bed-days among children aged 0–14 years
By contrast, cardiovascular disease is much less common in this age group, at less than 1% of admissions and 1% of bed-days.
The greatest number of bed-days in this age group were for congenital conditions (present at birth, either inherited or caused by environmental factors) and perinatal conditions (present in the time immediately before and after birth): 2.1% for admissions, and 4.8% for bed-days.
Acute lower respiratory tract infections were responsible for 3.5% of admissions and 3.3% of bed-days in this age group – a greater proportion when compared to admissions and bed-days for acute LRTI in the overall population.

Adults aged 15−64 years
In the UK in 2011, lung diseases accounted for 5% of all hospital admissions and 5% of inpatient bed-days occupied by adults aged 15-64 years.
Pneumonia and COPD are the main lung diseases responsible for hospital admissions in this age group.

Adults over 65 years
In the UK in 2011, lung diseases accounted for 13% of all hospital admissions and 13% of inpatient bed-days occupied by adults aged over 65. This is a higher proportion than in younger age groups.
Pneumonia and COPD were responsible for most hospital admissions and bed-days in this age group.

Regional variations in hospital admissions and bed-days
Patterns for emergency hospital admissions vary across the UK, very much in keeping with variations in death rates.
Relative risk of emergency hospital admissions for any lung disease, by local authority district (England, Scotland and Wales), 2010
Relative risk is used to compare risk in different groups of people. In medical research, all sorts of groups are compared to others to see whether belonging to one group or other puts you at greater risk of something. In this instance, relative risk has been used to see how people’s risk of being admitted to hospital for any lung disease varies according to where they live in England, Scotland and Wales.
