Life Table
In actuarial science and demography, a life table (also called a mortality table or actuarial table) is a table which shows, for each age, the probability that a person of that age will die before their next birthday ("probability of death"). 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. There are two types of life tables used in actuarial science. The period life table represents mortality rates during a specific time period for a certain population. A cohort life table, often referred to as a generation life table, is used to represent the overall mortality rates of a certain population's entire lifetime. They must have had to be born during the same specific time interval. A cohort life table is more frequently used because it is able to m ...

Emigration
Emigration is the act of leaving a resident country or place of residence with the intent to settle elsewhere (to permanently leave a country). Conversely, immigration describes the movement of people into one country from another (to permanently move to a country). A migrant ''emigrates'' from their old country, and ''immigrates'' to their new country. Thus, both emigration and immigration describe International migration, migration, but from different countries' perspectives. Demographers examine push and pull factors for people to be pushed out of one place and attracted to another. There can be a desire to escape negative circumstances such as shortages of land or jobs, or unfair treatment. People can be pulled to the opportunities available elsewhere. Fleeing from oppressive conditions, being a refugee and Asylum seeker, seeking asylum to get Refugee#Refugee status, refugee status in a foreign country, may lead to permanent emigration. Forced displacement refers to group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force Of Mortality
In actuarial science, force of mortality represents the instantaneous rate of mortality at a certain age measured on an annualized basis. It is identical in concept to failure rate, also called hazard function, in reliability theory. Motivation and definition In a life table, we consider the probability of a person dying from age ''x'' to ''x'' + 1, called ''q''''x''. In the continuous case, we could also consider the conditional probability of a person who has attained age (''x'') dying between ages ''x'' and ''x'' + ''Δx'', which is :P_(\Delta x)=P(x |
Radix
In a positional numeral system, the radix (radices) or base is the number of unique digits, including the digit zero, used to represent numbers. For example, for the decimal system (the most common system in use today) the radix is ten, because it uses the ten digits from 0 through 9. In any standard positional numeral system, a number is conventionally written as with ''x'' as the string of digits and ''y'' as its base. For base ten, the subscript is usually assumed and omitted (together with the enclosing parentheses), as it is the most common way to express value. For example, (the decimal system is implied in the latter) and represents the number one hundred, while (100)2 (in the binary system with base 2) represents the number four. Etymology ''Radix'' is a Latin word for "root". ''Root'' can be considered a synonym for ''base,'' in the arithmetical sense. In numeral systems Generally, in a system with radix ''b'' (), a string of digits denotes the number , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data From National Vital Statistics Report TPx
Data ( , ) are a collection of discrete or continuous values that convey information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally. A datum is an individual value in a collection of data. Data are usually organized into structures such as tables that provide additional context and meaning, and may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data are commonly used in scientific research, economics, and virtually every other form of human organizational activity. Examples of data sets include price indices (such as the consumer price index), unemployment rates, literacy rates, and census data. In this context, data represent the raw facts and figures from which useful information can be extracted. Data are collected using techniques such as m ...

Insurance
Insurance is a means of protection from financial loss in which, in exchange for a fee, a party agrees to compensate another party in the event of a certain loss, damage, or injury. It is a form of risk management, primarily used to protect against the risk of a contingent or uncertain loss. An entity which provides insurance is known as an insurer, insurance company, insurance carrier, or underwriter. A person or entity who buys insurance is known as a policyholder, while a person or entity covered under the policy is called an insured. The insurance transaction involves the policyholder assuming a guaranteed, known, and relatively small loss in the form of a payment to the insurer (a premium) in exchange for the insurer's promise to compensate the insured in the event of a covered loss. The loss may or may not be financial, but it must be reducible to financial terms. Furthermore, it usually involves something in which the insured has an insurable interest established by o ...

Marital Status
Civil status, or marital status, are the distinct options that describe a person's relationship with a significant other. '' Married'', '' single'', '' divorced'', and ''widowed'' are examples of civil status. ''Civil status'' and ''marital status'' are terms used in forms, vital records, and other documents to ask or indicate whether a person is married or single. In the simplest contexts, no further distinction is made. A status of ''married'' means that a person was wed in a manner legally recognized by their jurisdiction. A person's specified civil status might also be ''married'' if they are in a civil union or common-law marriage. The civil status of a person who is legally separated is ''married''. Whether a cohabiting couple (such as in a domestic partnership) have a civil status of "married" depends on the circumstances and the jurisdiction. In addition to those who have never married, ''single'' status applies to people whose relationship with a significant other ...

Labor Force
In macroeconomics, the workforce or labour force is the sum of people either working (i.e., the employed) or looking for work (i.e., the unemployed): \text = \text + \text Those neither working in the marketplace nor looking for work are out of the labour force. The sum of the labour force and out of the labour force results in the noninstitutional civilian population, that is, the number of people who (1) work (i.e., the employed), (2) can work but don't, although they are looking for a job (i.e., the unemployed), or (3) can work but don't, and are not looking for a job (i.e., out of the labour force). Stated otherwise, the noninstitutional civilian population is the total population minus people who cannot or choose not to work (children, retirees, soldiers, and incarcerated people). The noninstitutional civilian population is the number of people potentially available for civilian employment. \begin \text &= \text + \text \\ & ...

Disability
Disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within a given society. Disabilities may be Cognitive disability, cognitive, Developmental disability, developmental, Intellectual disability, intellectual, mental disorder#Disability, mental, physical disability, physical, Sense, sensory, or a combination of multiple factors. Disabilities can be Birth defect, present from birth or can be acquired during a person's lifetime. Historically, disabilities have only been recognized based on a narrow set of criteria—however, disabilities are not binary and can be present in unique characteristics depending on the individual. A disability may be readily visible, or Invisible disability, invisible in nature. The United Nations Convention on the Rights of Persons with Disabilities defines disability as including: Disabilities have been perceived differently throughout history, through a variety of ...

Healthy Life Years
The Healthy Life Years (HLY) indicator, also known as disability-free life expectancy (DFLE) or Sullivan's Index, is a European structural indicator computed by Eurostat. It is one of the summary measures of population health, known as health expectancies, composite measures of health that combine mortality and morbidity data to represent overall population health on a single indicator. HLY measures the number of remaining years that a person is expected to live at a certain age without the disability. History The European Union has decided to include a small set of health expectancies among its European Community Health Indicators (ECHI) to provide synthetic measures of disability, chronic morbidity, and perceived health. Therefore the Minimum European Health Module (MEHM), composed of 3 general questions covering these dimensions, has been introduced into the Eurostat EU-Statistics on Income and Living Conditions Survey (EU-SILC) to improve the comparability of health expect ...

Disability-adjusted Life Year
A disability-adjusted life year (DALY) is a measure of overall disease burden, representing a year 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. The concept has become more common in the field of public health and health impact assessment (HIA). It combines both potential years of life lost due to premature death ( mortality) and to poor health or disability ( morbidity) into a single metric. DALY, QALY and HALY DALY is closely related to QALY and HALY. A QALY (quality-adjusted life year) measures both the length and quality of life. QALYs are commonly used to assess the cost-effectiveness of medical or public health interventions and to guide decisions aimed at improving social welfare. However, QALYs measure only the benefit of medical interventions, not the overall burden of disease. Like DALY, HALY (health-adjusted life years) assesses the combined effec ...

Tobacco Smoking
Tobacco smoking is the practice of burning tobacco and ingesting the resulting smoke. The smoke may be inhaled, as is done with cigarettes, or released from the mouth, as is generally done with pipes and cigars. The practice is believed to have begun as early as 5000–3000 BC in Mesoamerica and South America. Tobacco was introduced to Eurasia in the late 17th century by European colonists, where it followed common trade routes. The practice encountered criticism from its first import into the Western world onward but embedded itself in certain strata of several societies before becoming widespread upon the introduction of automated cigarette-rolling apparatus. Smoking is the most common method of consuming tobacco, and tobacco is the most common substance smoked. The agricultural product is often mixed with additives and then combusted. The resulting smoke, which contains various active substances, the most significant of which is the addictive psychostimulant drug nicotine ...
