Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, current age, and other demographic factors like sex. The most commonly used measure is life expectancy at birth (LEB), which can be defined in two ways. Cohort LEB is the mean length of life of a birth cohort and can be computed only for cohorts born so long ago that all their members have died. Period LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year.
The population of the United Kingdom was estimated at over 67.0 million in 2020. It is the 21st most populated country in the world and has a population density of 270 people per square kilometre, with England having significantly greater density than Wales, Scotland, and Northern Ireland. Almost a third of the population lives in South East England, which is predominantly urban and suburban, with about 9 million in the capital city, London, whose population density is just over 5,200 per square kilometre.
The population of Africa has grown rapidly over the past century and consequently shows a large youth bulge, further reinforced by a low life expectancy of below 50 years in some African countries. Total population as of 2020 is estimated at more than 1.3 billion, with a growth rate of more than 2.5% p.a. The total fertility rate for Sub-Saharan Africa is 4.7 as of 2018, the highest in the world according to the World Bank. The most populous African country is Nigeria with over 206 million inhabitants as of 2020 and a growth rate of 2.6% p.a.
The ageing of Europe, also known as the greying of Europe, is a demographic phenomenon in Europe characterised by a decrease in fertility, a decrease in mortality rate, and a higher life expectancy among European populations. Low birth rates and higher life expectancy contribute to the transformation of Europe's population pyramid shape. The most significant change is the transition towards a much older population structure, resulting in a decrease in the proportion of the working age while the number of the retired population increases. The total number of the older population is projected to increase greatly within the coming decades, with rising proportions of the post-war baby-boom generations reaching retirement. This will cause a high burden on the working age population as they provide for the increasing number of the older population.
Health in the United Kingdom refers to the overall health of the population of the United Kingdom. This includes overall trends such as life expectancy and mortality rates, mental health of the population and the suicide rate, smoking rates, alcohol consumption, prevalence of diseases within the population and obesity in the United Kingdom. Three of these, smoking rates, alcohol consumption and obesity are above the OECD average.
Australia is a high income country, and this is reflected in the good status of health of the population overall. In 2011, Australia ranked 2nd on the United Nations Development Programme’s Human Development Index, indicating the level of development of a country. Despite the overall good status of health, the disparities occurring in the Australian healthcare system are a problem. The poor and those living in remote areas as well as indigenous people are, in general, less healthy than others in the population, and programs have been implemented to decrease this gap. These include increased outreach to the indigenous communities and government subsidies to provide services for people in remote or rural areas.
Health in Iraq refers to the country's public healthcare system and the overall health of the country's population. Iraq belongs to WHO health region Eastern Mediterranean and classified as upper middle according to World Bank income classification 2013. The state of health in Iraq has fluctuated during its turbulent recent history and specially during the last 4 decade. The country had one of the highest medical standards in the region during the period of 1980s and up until 1991, the annual total health budget was about $450 million in average. The 1991 Gulf War incurred Iraq's major infrastructures a huge damage. This includes health care system, sanitation, transport, water and electricity supplies. UN economic sanctions aggravated the process of deterioration. The annual total health budget for the country, a decade after the sanctions had fallen to $22 million which is barely 5% of what it was in 1980s. During its last decade, the regime of Saddam Hussein cut public health funding by 90 percent, contributing to a substantial deterioration in health care. During that period, maternal mortality increased nearly threefold, and the salaries of medical personnel decreased drastically. Medical facilities, which in 1980 were among the best in the Middle East, deteriorated. Conditions were especially serious in the south, where malnutrition and water-borne diseases became common in the 1990s. Health indicators deteriorated during the 1990s. In the late 1990s, Iraq's infant mortality rates more than doubled. Because treatment and diagnosis of cancer and diabetes decreased in the 1990s, complications and deaths resulting from those diseases increased drastically in the late 1990s and early 2000s.
Health care services in Nepal are provided by both public and private sectors and are generally regarded as failing to meet international standards. Prevalence of disease is significantly higher in Nepal than in other South Asian countries, especially in rural areas. Moreover, the country's topographical and sociological diversity results in periodic epidemics of infectious diseases, epizootics and natural hazards such as floods, forest fires, landslides, and earthquakes. A large section of the population, particularly those living in rural poverty, are at risk of infection and mortality by communicable diseases, malnutrition and other health-related events. Nevertheless, some improvements in health care can be witnessed; most notably, there has been significant improvement in the field of maternal health. These improvements include:
Singapore is one of the wealthiest countries in the world, with a gross domestic product (GDP) per capita of more than $57,000. Life expectancy at birth is 82.3 and infant mortality is 2.7 per 1000 live births. The population is ageing and by 2030, 20% will be over 65. However it is estimated that about 85% of those over 65 are healthy and reasonably active. Singapore has a universal health care system.
The current population of Myanmar is 54.05 million. It was 27.27 million in 1970. The general state of healthcare in Myanmar is poor. The military government of 1962-2011 spent anywhere from 0.5% to 3% of the country's GDP on healthcare. Healthcare in Myanmar is consistently ranked among the lowest in the world. In 2015, in congruence with a new democratic government, a series of healthcare reforms were enacted. In 2017, the reformed government spent 5.2% of GDP on healthcare expenditures. Health indicators have begun to improve as spending continues to increase. Patients continue to pay the majority of healthcare costs out of pocket. Although, out of pocket costs were reduced from 85% to 62% from 2014 to 2015. They continue to drop annually. The global average of healthcare costs paid out of pocket is 32%. Both public and private hospitals are understaffed due to a national shortage of doctors and nurses. Public hospitals lack many of the basic facilities and equipment. WHO consistently ranks Myanmar among the worst nations in healthcare.
According to the World Bank income level classification, Portugal is considered to be a high income country. Its population was of 10,283,822 people, by 1 July 2019. WHO estimates that 21.7% of the population is 65 or more years of age (2018), a proportion that is higher than the estimates for the WHO European Region.
Italy is known for its generally very good health system, and the life expectancy is 80 for males and 85 for females, placing the country 5th in the world for life expectancy, and low infant mortality. In comparison to other Western countries, Italy has a relatively low rate of adult obesity, as there are several health benefits of the Mediterranean diet. The proportion of daily smokers was 22% in 2012, down from 24.4% in 2000 but still slightly above the OECD average. Smoking in public places including bars, restaurants, night clubs and offices has been restricted to specially ventilated rooms since 2005.
Health in Russia deteriorated rapidly following the dissolution of the Soviet Union, particularly for men, as a result of social and economic changes.
Family planning in India is based on efforts largely sponsored by the Indian government. From 1965 to 2009, contraceptive usage has more than tripled and the fertility rate has more than halved, but the national fertility rate in absolute numbers remains high, causing concern for long-term population growth. India adds up to 1,000,000 people to its population every 20 days. Extensive family planning has become a priority in an effort to curb the projected population of two billion by the end of the twenty-first century.
The United Kingdom government austerity programme is a fiscal policy that was adopted for a period in the early 21st century following the Great Recession. The term was used by the Coalition and Conservative governments in office from 2010 to 2019, and again during the 2021–present United Kingdom cost of living crisis.
The quality of health in Rwanda has historically been very low, both before and immediately after the 1994 genocide. In 1998, more than one in five children died before their fifth birthday, often from malaria. But in recent years Rwanda has seen improvement on a number of key health indicators. Between 2005 and 2013, life expectancy increased from 55.2 to 64.0, under-5 mortality decreased from 106.4 to 52.0 per 1,000 live births, and incidence of tuberculosis has dropped from 101 to 69 per 100,000 people. The country's progress in healthcare has been cited by the international media and charities. The Atlantic devoted an article to "Rwanda's Historic Health Recovery". Partners In Health described the health gains "among the most dramatic the world has seen in the last 50 years".
According to the Constitution of Albania, citizens are entitled to healthcare. The healthcare system in Albania is primarily public. The public system is made up of three tiers: primary care, secondary care, and tertiary care. Primary healthcare covers basic health needs. Secondary healthcare is needed when seeing a specialist after being referred to by a general doctor. Tertiary healthcare funds highly specialized medical care that is needed over a long duration of time. There are over 400 public clinics that offer both primary and secondary healthcare services, along with over 40 public hospitals that offer tertiary healthcare services.
New Zealand is a high income country, and this is reflected in the overall good health status of the population. However like other wealthy countries, New Zealand suffers from high rates of obesity and heart disease.
Montenegro is a country with an area of 13,812 square kilometres and a population of 620,029, according to the 2011 census. The country is bordered by Croatia, the Adriatic Sea, Bosnia, Herzegovina, Serbia, Kosovo and Albania. The most common health issues faced are non-communicable diseases accounting for 95% of all deaths. This is followed by 4% of mortality due to injury, and 1% due to communicable, maternal, perinatal and nutritional conditions. Other health areas of interest are alcohol consumption, which is the most prevalent disease of addiction within Montenegro and smoking. Montenegro has one of the highest tobacco usage rates across Europe. Life expectancy for men is 74 years, and life expectancy for women is 79.
In South Korea, aging refers to an increase in the proportion of senior citizens to the total population. The term "senior citizens" include those aged 65 or older. According to Article 3 no.1 of the Framework Act on Low Birthrate of an Aging Society, the term "aging population" refers to the increasing proportion of elderly people in the entire population.
