List Of Countries By Dependency Ratio
Dependency ratios are a measure of the age structure of a population. They indicate the proportion of individuals that are likely to be economically "dependent" on the support of others. Dependency ratios relate the numbers of children (ages 0–14) and the elderly (ages 65+) to the number of adults (ages 15–64). Changes in the dependency ratio provide an indication of potential social support requirements resulting from changes in population age structures. When fertility levels decline, the dependency ratio initially falls because the proportion of children decreases while the proportion of the population of working age increases. If fertility levels continue to decline, dependency ratios eventually increase because the proportion of the population of working age starts to decline and the proportion of elderly persons continues to increase. The ''total dependency ratio'' is the total numbers of the children (ages 0–14) and elderly (ages 65+) populations per 100 people of adul ...

Dependency Ratio
The dependency ratio is an age-population ratio of those typically not in the labor force (the ''dependent'' part ages 0 to 14 and 65+) and those typically in the labor force (the ''productive'' part ages 15 to 64). It is used to measure the pressure on the productive population. Consideration of the dependency ratio is essential for governments, economists, bankers, business, industry, universities and all other major economic segments which can benefit from understanding the impacts of changes in population structure. A low dependency ratio means that there are sufficient people working who can support the dependent population. A lower ratio could allow for better pensions and better health care for citizens. A higher ratio indicates more financial stress on working people and possible political instability. While the strategies of increasing fertility and of allowing immigration especially of younger working age people have been formulas for lowering dependency ratios, future ...

Multiplicative Inverse
In mathematics, a multiplicative inverse or reciprocal for a number ''x'', denoted by 1/''x'' or ''x''−1, is a number which when multiplied by ''x'' yields the multiplicative identity, 1. The multiplicative inverse of a fraction ''a''/''b'' is ''b''/''a''. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4. The reciprocal function, the function ''f''(''x'') that maps ''x'' to 1/''x'', is one of the simplest examples of a function which is its own inverse (an involution). Multiplying by a number is the same as dividing by its reciprocal and vice versa. For example, multiplication by 4/5 (or 0.8) will give the same result as division by 5/4 (or 1.25). Therefore, multiplication by a number followed by multiplication by its reciprocal yields the original number (since the product of the number and its reciprocal is 1). The term ''reciproc ...

Cia World Fact Book
''The World Factbook'', also known as the ''CIA World Factbook'', is a reference resource produced by the Central Intelligence Agency (CIA) with almanac-style information about the countries of the world. The official print version is available from the Government Publishing Office. The ''Factbook'' is available in the form of a website that is partially updated every week. It is also available for download for use off-line. It provides a two- to three-page summary of the demographics, geography, communications, government, economy, and military of each of 267 international entities including U.S.-recognized countries, dependencies, and other areas in the world. ''The World Factbook'' is prepared by the CIA for the use of U.S. government officials, and its style, format, coverage, and content are primarily designed to meet their requirements. However, it is frequently used as a resource for academic research papers and news articles. As a work of the U.S. government, it is i ...
