Aging Statistics and Lifespan Key Facts and Takeaways

Aging across cultures and Countries

Lifespan, Healthy Lifespan and Life Expectancy

Life Expectancy rises with Wealth - Preston Curve

Life Expectancy and Wealth relationship is shown by the Preston curve shows cross-country data for 2005. The x-axis shows GDP per capita in 2005 international dollars, the y-axis shows life expectancy at birth. Each dot represents a particular country. Clearly the

Rapid Gains as Per Capita Income Rises from $100s to $1000

Individuals born in richer countries, on average, can expect to live longer than those born in poor countries.

Significantly at low levels of per capita income, further increases in income are associated with large gains in life expectancy

In-expensive anti-parasites and germ vaccinations: de-worming, DPT, malaria, Measles

Often very inexpensive methods can create huge local benefits

  • A ten cent pill single dose for de-worming has had huge benefits in India and Africa - often for years later in well-being, raised productivity and incomes.

The poorest countries economic growth may be necessary for improvements in health, as even the most inexpensive technologies have a cost of adoption that poor countries may not be able to afford.

Thus sanitation and a supply of clean water to prevent water-borne diseases, has a fixed cost but huge benefits.

Compulsory in-school and at-birth vaccinations have a huge benefit esp preventing DPT and measles. Polio vaccination is cheap and very effective in giving normal growth to children.

Control of disease vectors such as spraying malaria control chemicals and draining excess swamps also boosts health and productivity.

Malnutrition is a key factor

  • Basic foods and Vitamins eg Vit D prevents rickets, folic supplements are added to processed milk and flour to restore have cut neural tube defects considerably

Income : Health - a 2-way causality

Diseases such as malaria can short circuit the productivity and learning processes of the majority of children in an area.

In turn better health may in turn raise the level of income but also its growth rate through its effect on education. Healthier children spend more time at school and learn faster, thus acquiring more human capital which translates into higher growth rates of incomes later in life.

Life Expectancy Sharp Bump above $2000/yr - As Infant Mortality falls

A more accurate nonparametric regression on the data produces a version of the curve which has a "hinge" – i.e. a kink in the relationship where the slope of the regression equation falls off significantly. This point occurs around the per capita income level of $2,045 (data for the year 2000) which is about the per capita income level of India. This level of income is generally associated with a crossing of a "epidemiological transition", where countries change from having most of their mortality occur due to infant mortality to that due to old age mortality, and from prevalence of infectious diseases to that of chronic diseases.

Gains Flatten at very wealthy levels > $18,000/yr

However, the link between income and life expectancy flattens out so at high levels of income, increased income has little associated change in life expectancy.

Nature of Economy makes a huge difference

The source of income growth, rather than growth itself has been shown to be significant, finding divergences from the Preston Curve partially explained by the main reason for uplift of per-capita income, and its equality of distribution.

Mining and Oil as basis of income growth has far less benefit than other industries

The mining dominated economies suffer in health and education. Perhaps this is due to inequality of distribution of fruits of output - typical in oil (bulk of income skimmed off top by Sheikhs/despots/dictators), and mine-ownership in hands of foreign corporations with crony capitalism and corruption preventing profits from going to the people.

Religion can make a HUGE impact

Catholicism used to deny contraception and abortion to women

Pro-live movements similarly kept a lot of black women with kids in welfare but poverty

As revealed by Freakanomics, with legalization of abortion, incomes of blacks in USA dramatically rose, and their health and lifespans.

Muslim traditionalism keep women marry early - more maternal and infant fatalities

Sub-Saharan African countries life expectancy declined mainly due to HIV/AIDS

Several poor countries in Sub-Saharan Africa have actually seen declines in life expectancy in the 1990s and 2000s as a result of the HIV/AIDS epidemic, even if their per capita incomes have increased during this time.

How Lifespans in Countries Stagnate or even Decline

Post USSR, Russian life expectancy fell dramatically on Drinking, poor social

Dictators can kill tens of millions - China's Mao, Cambodia Khymer Rouge as examples

Globalists, Elitists and Genocide = Hitler, Churchill, Clinton killed tens of millions TODO

USA Spends Twice other developed Countries - Gets negative value

In 2000, the USA lay just below the curve, indicating that it had a slightly lower life expectancy than other rich countries.

USA Guns, Cars, Drugs, Suicides and Opioids caused decline in Lifespan

  • US preventable deaths rapidly rose after Bush Jr regime killed FDA regulation and esp. Republican or Red States allowed Pharma companies to prescribe 200/100 individuals while Democratic Blue states like CA,MA only had 55/100 prescriptions.

Ironically smoking rates declined rapidly among adults so lung cancer deaths fell, but was being replaced by vaping, and thousands of deaths are being caused by unknown additives substances in it esp in cannabis infused vaping.

Optimizing Lifespan within a Population - Actionables

Social Politics/Policy can change Life Expectancy

Health Technology can change Life Expectancy

  • A - new health technology is uniformly applicable across countries

    In the 1900s with rapid advances new health technology has lifted the curve upwards! Preston's study was that the curve has shifted upwards during the 20th century. This means that life expectancy has increased in most countries, independently of changes in income. Preston credited education, better technology, vaccinations, improved provision of public health services, oral rehydration therapy and better nutrition with these exogenous improvements in health.

  • B - new health technology helps rich countries more

  • C - new health technology helps poor countries more

Large Variations within a Region

Indigenous peoples suffer on Reservations at hands of "Whites"

  • In three different countries (AU NZ and CA) even in 2007 the Aboriginal and indigenous peoples lifespans are 7-10 years less than the non-indigenous parts of their populations. - SRC Australia Department of Health

Long Living populations, Blue Zones

Seventh Day Adventists located in Loma Linda, CA

You would see a population that has a higher longevity than the average American. In addition, they also have a much lower risk of chronic disease. Seventh Day participants are practicing vegetarians because one of their religious beliefs is to respect the body. They do consume dairy products. Adventists practice a very healthy lifestyle that includes exercising regularly and avoiding smoking and alcohol.mediterranean-vegetables-stew-with-lamb
