Per capita income (PCI) or average income measures the average income earned per person in a given area in a specified year.
Demography is the statistical study of human populations: their size, composition, and how they change through the interplay of fertility (births), mortality (deaths), and migration.
The United States had an official estimated resident population of 334,914,895 on July 1, 2023, according to the U.S. Census Bureau. This figure includes the 50 states and Washington, D.C. but excludes the population of five unincorporated U.S. territories as well as several minor island possessions. The United States is the third most populous country in the world, and the most populous in the Americas and the Western Hemisphere. The Census Bureau showed a population increase of 0.4% for the twelve-month period ending in July 2022, below the world average annual rate of 0.9%. The total fertility rate in the United States estimated for 2022 is 1.665 children per woman, which is below the replacement fertility rate of approximately 2.1. By several metrics, including racial and ethnic background, religious affiliation, and percentage of rural and urban divide, Illinois is the most representative of the larger demography of the United States.
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.
A cohort study is a particular form of longitudinal study that samples a cohort, performing a cross-section at intervals through time. It is a type of panel study where the individuals in the panel share a common characteristic.
Human body weight is a person's mass or weight.
Diseases of affluence, previously called diseases of rich people, is a term sometimes given to selected diseases and other health conditions which are commonly thought to be a result of increasing wealth in a society. Also referred to as the "Western disease" paradigm, these diseases are in contrast to "diseases of poverty", which largely result from and contribute to human impoverishment. These diseases of affluence have vastly increased in prevalence since the end of World War II.
Disability-adjusted life years (DALYs) are a measure of overall disease burden, expressed as the number of years lost due to ill-health, disability, or early death. It was developed in the 1990s as a way of comparing the overall health and life expectancy of different countries.
Prevalence of tobacco use is reported by the World Health Organization (WHO), which focuses on cigarette smoking due to reported data limitations. Smoking has therefore been studied more extensively than any other form of consumption.
Disease burden is the impact of a health problem as measured by financial cost, mortality, morbidity, or other indicators. It is often quantified in terms of quality-adjusted life years (QALYs) or disability-adjusted life years (DALYs). Both of these metrics quantify the number of years lost due to disability (YLDs), sometimes also known as years lost due to disease or years lived with disability/disease. One DALY can be thought of as one year of healthy life lost, and the overall disease burden can be thought of as a measure of the gap between current health status and the ideal health status. According to an article published in The Lancet in June 2015, low back pain and major depressive disorder were among the top ten causes of YLDs and were the cause of more health loss than diabetes, chronic obstructive pulmonary disease, and asthma combined. The study based on data from 188 countries, considered to be the largest and most detailed analysis to quantify levels, patterns, and trends in ill health and disability, concluded that "the proportion of disability-adjusted life years due to YLDs increased globally from 21.1% in 1990 to 31.2% in 2013." The environmental burden of disease is defined as the number of DALYs that can be attributed to environmental factors. Similarly, the work-related burden of disease is defined as the number of deaths and DALYs that can be attributed to occupational risk factors to human health. These measures allow for comparison of disease burdens, and have also been used to forecast the possible impacts of health interventions. By 2014, DALYs per head were "40% higher in low-income and middle-income regions."
A growth chart is used by pediatricians and other health care providers to follow a child's growth over time. Growth charts have been constructed by observing the growth of large numbers of healthy children over time. The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately. Growth charts can also be used to predict the expected adult height and weight of a child because, in general, children maintain a fairly constant growth curve. When a child deviates from his or her previously established growth curve, investigation into the cause is generally warranted. Parameters used to analyze growth charts include weight velocity, height velocity, and whether someone's growth chart crosses percentiles. For instance, endocrine disorders can be associated with a decrease in height velocity and preserved weight velocity while normal growth variants are associated with a decrease in height and weight velocity that are proportional to each other. It's important to note that other parameters are more commonly used such as waist circumference for assessing obesity and skin fold difference for assessing malnutrition. Growth charts can also be compiled with a portion of the population deemed to have been raised in more or less ideal environments, such as nutrition that conforms to pediatric guidelines, and no maternal smoking. Charts from these sources end up with slightly taller but thinner averages.
The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 is a measure of health status and an abbreviated variant of it, the SF-6D, is commonly used in health economics as a variable in the quality-adjusted life year calculation to determine the cost-effectiveness of a health treatment. The SF-36 is also commonly utilized in health psychology research to examine the burden of disease. The original SF-36 stemmed from the Medical Outcome Study, MOS, which was conducted by the RAND Corporation. Since then a group of researchers from the original study released a commercial version of SF-36 while the original SF-36 is available in public domain license free from RAND. A shorter version is the SF-12, which contains 12 items rather than 36. If having only adequate physical and mental health summary scores is of interest, "then the SF12 may be the instrument of choice".
Life expectancy has been rising rapidly and South Korea ranked 3rd in the world for life expectancy. South Korea has among the lowest HIV/AIDS adult prevalence rate in the world, with just 0.1% of the population being infected, significantly lower than the U.S. at 0.6%, France's 0.4%, and the UK's 0.3% prevalence rate. South Korea has a good influenza vaccination rate, with a total of 43.5% of the population being vaccinated in 2019. A new measure of expected human capital calculated for 195 countries from 1920 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. South Korea had the sixth highest level of expected human capital with 26 health, education, and learning-adjusted expected years lived between age 20 and 64 years.
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.
Obesity is common in the United States and is a major health issue associated with numerous diseases, specifically an increased risk of certain types of cancer, coronary artery disease, type 2 diabetes, stroke, and cardiovascular disease, as well as significant increases in early mortality and economic costs.
According to 2007 statistics from the World Health Organization (WHO), Australia has the third-highest prevalence of overweight adults in the English-speaking world. Obesity in Australia is an "epidemic" with "increasing frequency." The Medical Journal of Australia found that obesity in Australia more than doubled in the two decades preceding 2003, and the unprecedented rise in obesity has been compared to the same health crisis in America. The rise in obesity has been attributed to poor eating habits in the country closely related to the availability of fast food since the 1970s, sedentary lifestyles and a decrease in the labour workforce.
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.
Globally, an estimated 537 million adults are living with diabetes, according to 2019 data from the International Diabetes Federation. Diabetes was the 9th-leading cause of mortality globally in 2020, attributing to over 2 million deaths annually due to diabetes directly, and to kidney disease due to diabetes. The primary causes of type 2 diabetes is diet and physical activity, which can contribute to increased BMI, poor nutrition, hypertension, alcohol use and smoking, while genetics is also a factor. Diabetes prevalence is increasing rapidly; previous 2019 estimates put the number at 463 million people living with diabetes, with the distributions being equal between both sexes icidence peaking around age 55 years old. The number is projected to 643 million by 2030, or 7079 individuals per 100,000, with all regions around the world continue to rise. Type 2 diabetes makes up about 85-90% of all cases. Increases in the overall diabetes prevalence rates largely reflect an increase in risk factors for type 2, notably greater longevity and being overweight or obese. The prevalence of African Americans with diabetes is estimated to triple by 2050, while the prevalence of whites is estimated to double. The overall prevalence increases with age, with the largest increase in people over 65 years of age. The prevalence of diabetes in America is estimated to increase to 48.3 million by 2050.
Indigenous health in Australia examines health and wellbeing indicators of Indigenous Australians compared with the rest of the population. Statistics indicate that Aboriginal Australians and Torres Strait Islanders are much less healthy than other Australians. Various government strategies have been put into place to try to remediate the problem; there has been some improvement in several areas, but statistics between Indigenous Australians and the rest of the Australian population still show unacceptable levels of difference.
