Post-aging Society
The societal effects of negligible senescence considers a scenario where negligible senescence is achieved on a societal wide level in humans. There is much controversy about the realistic timeline of such a scenario. The predictions vary in time starting from 2037 till later than the 21st century. The effects of negligible senescence has a profound impact on economy, climate, demographics and impacts social structures. The baseline scenario ''ceteris paribus'' of negligible senescence is more population growth while a larger healthier labor force would spur economic growth. Definition and characteristics Senescence is defined as the gradual deterioration of functional characteristics. The word senescence can either refer to cell biology, cellular senescence or to senescence of a whole organism. Negligible senescence is therefore defined as the lack of senescence or a very small amount of senescence. Which implies that mortality rate, mortality and morbidity from most causes is eli ...

Negligible Senescence
Negligible senescence is a term coined by biogerontology, biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging (senescence), such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age. There are many species where scientists have seen no increase in mortality after maturity. This may mean that the lifespan of the organism is so long that researchers' subjects have not yet lived up to the time when a measure of the species' longevity can be made. Turtles, for example, were once thought to lack senescence, but more extensive observations have found evidence of decreasing fitness with age. Study of negligibly senescent animals may provide clues that lead to better understanding of the aging process and influence evolution of aging, theories of aging. The phenomenon of negligible senescence in some animals is a traditional argument for attempting to achieve similar negligible ...

SENS Research Foundation
The SENS Research Foundation is a non-profit organization that does research programs and public relations work for the application of regenerative medicine to aging. It was founded in 2009, located in Mountain View, California, US. The organization publishes its reports annually. History Before the foundation was founded in March 2009, the SENS research program was mainly pursued by the Methuselah Foundation, co-founded by Aubrey de Grey and David Gobel. When the SENS rejuvenation approach was announced in the 2000s, while some biogerontologists supported the SENS program, many contended that the ultimate goals of de Grey's programme were too speculative given the state of technology and referred to it as "fantasy rather than science". By the mid-2010s, the rejuvenation approach gained traction with multiple startup companies created from SENS research findings. In 2021, entrepreneur Michael Greve pledged another €300 million for rejuvenation biotechnology startup compani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GDP Per Capita 2100 - Negligible Senescence
Gross domestic product (GDP) is a monetary measure of the total market value of all the final goods and services produced and rendered in a specific time period by a country or countries. GDP is often used to measure the economic performance of a country or region. Several national and international economic organizations maintain definitions of GDP, such as the OECD and the International Monetary Fund. GDP is often used as a metric for international comparisons as well as a broad measure of economic progress. It is often considered to be the world's most powerful statistical indicator of national development and progress. The GDP can be divided by the total population to obtain the average GDP per capita. Total GDP can also be broken down into the contribution of each industry or sector of the economy. Nominal GDP is useful when comparing national economies on the international market according to the exchange rate. To compare economies over time inflation can be adjusted by ...

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, futur ...

Productivity
Productivity is the efficiency of production of goods or services expressed by some measure. Measurements of productivity are often expressed as a ratio of an aggregate output to a single input or an aggregate input used in a production process, i.e. output per unit of input, typically over a specific period of time. The most common example is the (aggregate) labour productivity measure, one example of which is GDP per worker. There are many different definitions of productivity (including those that are not defined as ratios of output to input) and the choice among them depends on the purpose of the productivity measurement and data availability. The key source of difference between various productivity measures is also usually related (directly or indirectly) to how the outputs and the inputs are aggregated to obtain such a ratio-type measure of productivity. Productivity is a crucial factor in the production performance of firms and nations. Increasing national productivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demographic Transition
In demography, demographic transition is a phenomenon and theory in the Social science, social sciences referring to the historical shift from high birth rates and high Mortality rate, death rates to low birth rates and low death rates as societies attain more technology, education (especially of female education, women), and economic development. The demographic transition has occurred in most of the world over the past two centuries, bringing the unprecedented population growth of the Malthusianism, post-Malthusian period, then reducing birth rates and population growth significantly in all regions of the world. The demographic transition strengthens economic growth process through three changes: a reduced dilution of capital and land stock, an increased investment in human capital, and an increased size of the labour force relative to the total population and changed age population distribution. Although this shift has occurred in many Developed country, industrialized countries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population Ageing
Population ageing is an overall change in the ages of a population. This can typically be summarised in a single parameter as an increase in the median age. Causes are a long-term decline in fertility rates and a decline in mortality rates. Most countries now have declining mortality rates and an ageing population: trends that emerged first in developed countries but are now also seen in virtually all developing countries. In most developed countries, population ageing started in the late 19th century. By the late 20th century, the world population as a whole was also ageing. The proportion of people aged 65 and above accounts for 6% of the total population. This reflects a historic overall decline in the world's average fertility rate. That is the case for every country in the world except the 18 countries designated as "demographic outliers" by the United Nations. The aged population is currently at its highest level in human history. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Developed Countries
A developed country, or advanced country, is a sovereign state that has a high quality of life, developed economy, and advanced technological infrastructure relative to other less industrialized nations. Most commonly, the criteria for evaluating the degree of economic development are the gross domestic product (GDP), gross national product (GNP), the per capita income, level of industrialization, amount of widespread infrastructure and general standard of living. Which criteria are to be used and which countries can be classified as being developed are subjects of debate. Different definitions of developed countries are provided by the International Monetary Fund and the World Bank; moreover, HDI ranking is used to reflect the composite index of life expectancy, education, and income per capita. In 2025, 40 countries fit all three criteria, while an additional 21 countries fit two out of three. Developed countries have generally more advanced post-industrial economies, ...

Population Pyramid Forecast - Negligible Senescence
Population is a set of humans or other organisms in a given region or area. Governments conduct a census to quantify the resident population size within a given jurisdiction. The term is also applied to non-human animals, microorganisms, and plants, and has specific uses within such fields as ecology and genetics. Etymology The word ''population'' is derived from the Late Latin ''populatio'' (a people, a multitude), which itself is derived from the Latin word ''populus'' (a people). Use of the term Social sciences In sociology and population geography, population refers to a group of human beings with some predefined feature in common, such as location, race, ethnicity, nationality, or religion. Ecology In ecology, a population is a group of organisms of the same species which inhabit the same geographical area and are capable of interbreeding. The area of a sexual population is the area where interbreeding is possible between any opposite-sex pair within the area ...

Menopause
Menopause, also known as the climacteric, is the time when Menstruation, menstrual periods permanently stop, marking the end of the Human reproduction, reproductive stage for the female human. It typically occurs between the ages of 45 and 55, although the exact timing can vary. Menopause is usually a natural change related to a decrease in circulating blood estrogen levels. It can occur earlier in those who smoke tobacco. Other causes include surgery that removes both ovaries, some types of chemotherapy, or anything that leads to a decrease in hormone levels. At the physiological level, menopause happens because of a decrease in the ovaries' production of the hormones estrogen and progesterone. While typically not needed, measuring hormone levels in the blood or urine can confirm a diagnosis. Menopause is the opposite of menarche, the time when periods start. In the years before menopause, a woman's periods typically become irregular, which means that periods may be longer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Fertility Rate
The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of their reproductive life. As of 2023, the total fertility rate varied widely across the world, from 0.7 in South Korea, to 6.1 in Niger. Among sovereign countries that were not city states or had a very small number of inhabitants, in 2024 the following countries had a TFR of 1.0 or lower: South Korea, Taiwan, and Ukraine; the following countries had a TFR of 1.2 or lower: Chile, China, Japan, Malta, Poland, and Spain. Fertility tends to be inversely correlated with levels of economic development. Historically, developed countries have significantly lower fertility rates, generally correlated with greater wealth, education, urbanization, and other factors. Conversely, in least developed countries, ferti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population Pyramid
A population pyramid (age structure diagram) or "age-sex pyramid" is a graphical illustration of the distribution of a population (typically that of a country or region of the world) by age groups and sex; it typically takes the shape of a pyramid when the population is growing. Males are usually shown on the left and females on the right, and they may be measured in absolute numbers or as a percentage of the total population. The pyramid can be used to visualize the age of a particular population. It is also used in ecology to determine the overall age distribution of a population; an indication of the reproductive capabilities and likelihood of the continuation of a species. Number of people per unit area of land is called population density. Structure A population pyramid often contains continuous stacked-histogram bars, making it a horizontal bar diagram. The population size is shown on the x-axis (horizontal) while the age-groups are represented on the y-axis (vertical). The ...
