Median age An age that divides a population into two numerically equal groups; That is, half of the people are younger than that age and half are older. The present value, V, the initial starting point subject to exponential growth, can be determined by multiplying the starting value S by the sum of one plus the interest rate R charged to the power of t, or the number of periods elapsed. The term “population explosion” (or “population bomb”) used to describe the 20th century global trend of rapid population growth resulting from a global birth rate much higher than the global death rate. Business growth can be measured in several dimensions, but all follow the same basic approach, which is to take the difference between the current level and the previous level and divide that amount by the previous level. This allows us to assess a company`s earnings growth by comparing its net income from the current period with the previous one. Analysts also look at revenue growth, stock price appreciation, and dividend growth in the same way. Low overall dependence Continued immigration of working-age adults, a small part of whose population is over 65, leads to low overall dependence. Some industries also have growth rates. Each industry has a unique reference number for the growth rates against which its performance is measured. For example, state-of-the-art companies tend to have higher annual growth rates than a mature industry such as retail. Industry growth rates can be used as a benchmark for companies that want to measure their performance against their competitors. Growth rate The number of persons added to (or deducted) from a population in a year due to natural growth and net migration, expressed as a percentage of the population at the beginning of the period.
Prevalence rate Number of people suffering from a particular disease at a given time, per 1,000 inhabitants at risk. Percentage of the urban population in the total population living in areas designated as “urban” by that country or by the United Nations. Malthus, Thomas R. (1766-1834) English clergyman and economist, famous for his theory (set out in the Essay on the Principle of Population) that the world`s population tends to grow faster than the food supply and that if fertility is not controlled (through late marriage or celibacy), famine, disease and war must serve as natural restrictions on the population. See Neo-Malthusian. Economic infrastructure Economic infrastructure includes a country`s internal facilities that enable commercial and financial activities, such as communication, transmission and distribution networks; financial institutions and markets; and energy supply systems. World population growth of 10,000 BC. J.-C. to 2019 AD Data from: United Nations Marriage The frequency, characteristics and dissolution of marriages in a population. In finance, exponential growth most often occurs in the context of compound interest. Mortality table Tabular representation of life expectancy and probability of dying at any age (or age group) for a given population, according to the age-specific mortality rates prevailing at that time. The life table gives an organized and complete picture of the mortality of a population.
Demographic forecastIng of future changes in population figures taking into account certain assumptions about future trends in fertility, mortality and migration rates. Demographers often make low, medium, and high projections of the same population based on different assumptions about how these rates will change in the future. Mortality Deaths in the context of population change. Educated (millennial) youth are a third group of wishes. This represents a talent pool – something the cutting-edge industry is looking for in a community where it can settle. Countries in the MENA region The Middle East and North Africa (MENA) is an economically diversified region that includes both the oil-rich economies of the Gulf and resource-poor countries relative to population. The economic fate of the region for much of the last quarter century has been heavily influenced by two factors: the price of oil and the legacy of economic policies and structures that had emphasized a leading role for the state. The MENA region includes: Algeria, Bahrain, Djibouti, Egypt, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Libya, Malta, Morocco.
Oman, Qatar, Saudi Arabia, Syria, Tunisia, United Arab Emirates, West Bank and Gaza, and Yemen. Amazon, for example, reported revenue of $232.89 billion for the full year 2018; This represents growth of 30.93% compared to revenue of $177.9 billion in 2017. Amazon also reported that profit in 2018 was $10.07 billion, up from $3.03 billion in 2017, so the company`s year-over-year earnings growth rate was 232 percent. Net migration Estimated migration rate (immigration minus emigration) per 1,000 population. For some countries, data are derived in residual form from estimated birth, death and population growth rates. Brain drain Emigration of a significant portion of a country`s highly skilled and highly skilled workforce, usually to other countries that offer better economic and social opportunities (e.B. Doctors leaving a developing country to practice medicine in an industrialized country). Crude rate of each demographic event, calculated for an entire population. Demographic evolution Historical evolution of birth and death rates from a high to a low level in a population. The decline in mortality usually precedes the decline in fertility, which leads to rapid population growth during the transition period. Since stock prices are supposed to reflect the present value of a company`s future cash flows, a rise in the stock market implies an improvement in the growth rates expected for the company. Age-sex structure The composition of a population determined by the number or proportion of men and women in each age group.
The age-sex structure of a population is the cumulative result of past trends in fertility, mortality and migration. Information on the composition of age and sex is essential for describing and analyzing many other types of demographic data. See also Age pyramid. Population register A government data collection system in which the demographic and socio-economic characteristics of all or part of the population are permanently recorded. Denmark, Sweden and Israel are among the countries that maintain universal registers for demographic purposes and record the most important events (birth, marriage, resettlement, death) that happen to each individual, so that up-to-date information on the entire population is readily available. Other countries, such as the United States, maintain partial registries such as Social Security and voter registration for administrative purposes. The ultimate local goal of the new economy is to attract and retain these human resources: educated youth, seniors, immigrants and entrepreneurs. For the growth of the new economy, a community and a region should have a conscious, targeted and officially adopted strategy to attract the population. Such a strategy can include many of the same things the community does to attract tourists, attract medical staff to a local hospital, and more.
Urban countries differ in how they classify the population as “urban” or “rural”. Generally, a municipality or institution with a population of 2,000 or more is considered urban. A list of country definitions is published annually in the United Nations Demographic Yearbook. Dependency ratio An dependency ratio is the ratio between people in a dependent age group (people under 15 or 65 and over) and people in the economically productive age group (15 to 64) in a population. For example, a child dependency ratio of 0.45 means that for every 100 working-age adults, there are 45 children. Balancing equation A basic demographic formula used to estimate the total change in population between two points in time – or to estimate an unknown component of population change, assuming that the other components are known. The equilibrium equation encompasses all components of population change: births, deaths, immigration, emigration, immigration and emigration. Age-dependent ratio The ratio of persons in the age groups defined as dependants (under 15 and over 64 years of age) and persons in the age groups defined as economically productive (15-64 years).
Age structure Proportion of the total population in each age group. Gender refers to the economic, social, political and cultural attributes, constraints and opportunities associated with being a woman or a man. Social definitions of what it means to be a woman or a man vary from culture to culture and change over time. Gender is a socio-cultural expression of certain characteristics and roles associated with certain groups of people in relation to their gender and sexuality. Carrying capacity The maximum sustainable size of a resident population in a given ecosystem. .
