Age dependency ratio as of 2017 [1] 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.
In February 1949, Hans Singer, then working in the United Nations Department of Economic Affairs in New York City, published a paper titled "Post-war Price Relations between Under-developed and Industrialized Countries", which suggested that the terms of trade of underdeveloped countries had declined significantly between 1876 and 1948.
The relationship between interdependence and business cycles is calculated by the distance correlation matrices over a period of 10 years. The combination of results from the data presents the economic interdependence of countries over time.
The total dependency ratio is the total numbers of the children (ages 0–14) and elderly (ages 65+) populations per 100 people of adults (ages 15–64). A high total dependency ratio indicates that the adult population and the overall economy face a greater burden to support and provide social services for youth and elderly persons, who are often economically dependent.
A relative price is the price of a commodity such as a good or service in terms of another; i.e., the ratio of two prices. A relative price may be expressed in terms of a ratio between the prices of any two goods or the ratio between the price of one good and the price of a market basket of goods (a weighted average of the prices of all other goods available in the market).
Population decline can impact the funding for programs for retirees if the ratio of working age population to the retired population declines. For example, in Japan, there were 5.8 workers for every retiree in 1990 vs 2.3 in 2017 and a projected 1.4 in 2050. [10]
When Marx talked about "value relationships" or "value proportions" (German: Wertverhältnisse), he did not mean "the money" or "the price". Instead, he meant the ratio of value (or 'worth') that exist between products of human labour. These relationships can be expressed by the relative replacement costs of products as labour hours worked.
Societies who have entered the demographic window have smaller dependency ratio (ratio of dependents to working-age population) and therefore the demographic potential for high economic growth as favorable dependency ratios tend to boost savings and investments in human capital.
