Death rates in the 20th century is the ratio of deaths compared to the population around the world throughout the 20th century. When giving these ratios, they are most commonly expressed by number of deaths per 1,000 people per year. Many factors contribute to death rates such as cause of death, increasing the death rate, an ageing population, which could increase and decrease the death rates by birth rates, and improvements in public health, decreasing the death rate.
Non-Hodgkin lymphoma (NHL), also known as non-Hodgkin's lymphoma, is a group of blood cancers that includes all types of lymphomas except Hodgkin lymphomas. Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and tiredness. Other symptoms may include bone pain, chest pain, or itchiness. Some forms are slow-growing while others are fast-growing. Unlike Hodgkin lymphoma, which spreads contiguously, NHL is largely a systemic illness.
Mortality rate, or death rate, is a measure of the number of deaths in a particular population, scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. It is distinct from "morbidity", which is either the prevalence or incidence of a disease, and also from the incidence rate.
Uterine cancer, also known as womb cancer, includes two types of cancer that develop from the tissues of the uterus. Endometrial cancer forms from the lining of the uterus, and uterine sarcoma forms from the muscles or support tissue of the uterus. Endometrial cancer accounts for approximately 90% of all uterine cancers in the United States. Symptoms of endometrial cancer include changes in vaginal bleeding or pain in the pelvis. Symptoms of uterine sarcoma include unusual vaginal bleeding or a mass in the vagina.
Oral cancer, also known as oral cavity cancer or mouth cancer, is a cancer of the lining of the lips, mouth, or upper throat. In the mouth, it most commonly starts as a painless red or white patch, that thickens, gets ulcerated and continues to grow. When on the lips, it commonly looks like a persistent crusting ulcer that does not heal, and slowly grows. Other symptoms may include difficult or painful swallowing, new lumps or bumps in the neck, a swelling in the mouth, or a feeling of numbness in the mouth or lips.
In actuarial science and demography, a life table is a table which shows, for each age, the probability that a person of that age will die before their next birthday. In other words, it represents the survivorship of people from a certain population. They can also be explained as a long-term mathematical way to measure a population's longevity. Tables have been created by demographers including John Graunt, Reed and Merrell, Keyfitz, and Greville.
Health in Cuba refers to the overall health of the population of Cuba. Like the rest of the Cuban economy, Cuban medical care suffered following the end of Soviet subsidies in 1991; the stepping up of the US embargo against Cuba at this time also had an effect.
Crime has been recorded in the United States since its founding and has fluctuated significantly over time. Most available data underestimate crime before the 1930s, giving the false impression that crime was low in the early 1900s and had a sharp rise after. Instead, violent crime during the colonial period was likely three times higher than the highest modern rates in the data we have, and crime had been on the decline since colonial times. Within the better data for crime reporting and recording available starting in the 1930s, crime reached its broad, bulging modern peak between the 1970s and early 1990s. After 1992, crime rates have generally trended downwards each year, with the exceptions of a slight increase in property crimes in 2001 and increases in violent crimes in 2005–2006, 2014–2016 and 2020–2021.
Years of potential life lost (YPLL) or potential years of life lost (PYLL) is an estimate of the average years a person would have lived if they had not died prematurely. It is, therefore, a measure of premature mortality. As an alternative to death rates, it is a method that gives more weight to deaths that occur among younger people. An alternative is to consider the effects of both disability and premature death using disability adjusted life years.
Smoking, alcohol consumption and obesity in the Republic of Ireland occur at rates higher than the OECD average.
The Tajikistan health system is influenced by the former Soviet legacy. It is ranked as the poorest country within the WHO European region, including the lowest total health expenditure per capita. Tajikistan is ranked 129th as Human Development Index of 188 countries, with an Index of 0.627 in 2016. In 2016, the SDG Index value was 56. In Tajikistan health indicators such as infant and maternal mortality rates are among the highest of the former Soviet republics. In the post-Soviet era, life expectancy has decreased because of poor nutrition, polluted water supplies, and increased incidence of cholera, malaria, tuberculosis, and typhoid. Because the health care system has deteriorated badly and receives insufficient funding and because sanitation and water supply systems are in declining condition, Tajikistan has a high risk of epidemic disease.
The major causes of deaths in Finland are cardiovascular diseases, malignant tumors, dementia and Alzheimer's disease, respiratory diseases, alcohol related diseases and accidental poisoning by alcohol. In 2010, the leading causes of death among men aged 15 to 64 were alcohol related deaths, ischaemic heart disease, accident, suicides, lung cancer and cerebrovascular diseases. Among women the leading causes were breast cancer, alcohol related deaths, accidents, suicides, ischaemic heart disease and lung cancer.
The epidemiology of cancer is the study of the factors affecting cancer, as a way to infer possible trends and causes. The study of cancer epidemiology uses epidemiological methods to find the cause of cancer and to identify and develop improved treatments.
In 2006, life expectancy for males in Cyprus was 79 and for females 82 years. Infant mortality in 2002 was 5 per 1,000 live births, comparing favourably to most developed nations.
Cancer survival rates vary by the type of cancer, stage at diagnosis, treatment given and many other factors, including country. In general survival rates are improving, although more so for some cancers than others. Survival rate can be measured in several ways, median life expectancy having advantages over others in terms of meaning for people involved, rather than as an epidemiological measure.
Worldwide, breast cancer is the most common invasive cancer in women. Breast cancer comprises 22.9% of invasive cancers in women and 16% of all female cancers.
A new measure of expected human capital calculated for 195 countries from 1990 to 2016 and defined for each birth cohort as the expected years lived from age 20 to 64 years and adjusted for educational attainment, learning or education quality, and functional health status was published by The Lancet in September 2018. Latvia had the twenty-first highest level of expected human capital with 23 health, education, and learning-adjusted expected years lived between age 20 and 64 years.
Childhood cancer is cancer in a child. About 80% of childhood cancer cases in high-income countries can be successfully treated via modern medical treatments and optimal patient care. However, only about 10% of children diagnosed with cancer reside in high-income countries where the necessary treatments and care is available. Childhood cancer represents only about 1% of all types of cancers diagnosed in children and adults, It is often more complex than adult cancers with unique biological characteristics and research and treatment is yet very challenging and limited. For this reason, childhood cancer is often ignored in control planning, contributing to the burden of missed opportunities for its diagnoses and management in countries that are low- and mid-income.
