According to an OECD study, Italians always maintain the high ranking for life expectancy compared to 36 OECD countries, but if until 2008-2009 they were third after Japan and Switzerland, in recent years they are stable in fourth place, with a slight decrease in the result that passes, on average, from 83.3 years at the birth of 2016 to 83 in the following years and in the ranking is always first Japan with 84.2 years , followed by Switzerland (83.6) and Spain (83.4).

Gender in this case makes all the difference: women have a life expectancy of 85.2 years, while men stop at 80.8. But these results have a reverse effect on the ranking. Women become six-year-olds behind the OECD, after Japan, Spain, France, Korea and Switzerland, while men are fifth after Switzerland, Iceland, Japan and Norway.

But looking at life expectancy in both sexes at 65, things change completely.

The Italians, in fact, with 22.4 years, are always in sixth place after Japan, Spain, France, Switzerland and Korea, but the men, with 19.2 years, are in 11th place and before them there are the males of Switzerland, Iceland, Australia, France, Japan, New Zealand, Canada, Israel, Norway, Spain.

A fact that makes us think of the quality of life as the years progress, considering that Italy remains one of the "oldest" countries in Europe and the world.

On the other hand, the OECD average figure is 3.78 deaths per 1,000 live births, but Italy is better and Spain and Portugal are at 2.7, seventh after 2 in Japan and Finland, 2.1 in Slovenia, 2.3 in Norway and Estonia and 2.4 in Sweden.

The ranking on the opposite side is very different and the last in the ranking is Mexico where deaths per 1,000 live births count 12.3, followed by Turkey with 9.2, Chile with 7 and then the United States with 5.8 deaths and Canada with 4.5, always for every 1,000 live births.

The next step in the OECD analysis is to calculate the potential life years lost for all causes, per 100,000 people, for women and men, up to 75 years.

For every 100,000 Italian women up to 75 years, 2,364.3 years of life have been lost, placing Italy in sixth place after Japan (which has lost less than all: 2,144), Spain, Korea, Luxembourg and Iceland. The OECD average is 3,158.47 years.

For every 100,000 Italian men up to 75 years, 4,189.6 years were lost, with Italy seventh behind Switzerland (3,613.9 years, the best), Norway, Luxembourg, Sweden, Japan, the Netherlands and a OECD average of 6,135.9 years.

One figure that the OECD also provides is that of the causes of mortality from "intentional self-harm" (suicide) per 100,000 inhabitants. In this case, Italy is fifth in the ranking with 5.7 cases after Turkey (2.6), Greece (4), Mexico and Israel (5.4).

On lifestyles, the OECD survey is comprehensive in tobacco and alcohol use and for self-reported obesity.

In the first case – tobacco – the average Italian figure is higher than the OECD average: 19.9% of the population over 15 who smoke compared to 18.1% of the OECD average. Smoking less in Mexico (7.6%) Greece (27.3%). Compared to the average, both women and men are higher than the OECD, but among the first smokes after 15 years, 15 percent, while among males 25.1 percent. In this case, at both ends of the ranking are Korea with 3.5% and Austria with 22.1%, while for men Iceland with 9.1% and Turkey with 40.1%.

It is better in Italy with regard to alcohol consumption. In this case Italy is in eighth place and still with a value (litres per capita over 15 years) lower than the OECD average: 7.6 vs. 8.9. You drink less in Turkey (1.4) and more in Lithuania (12.3).

On self-reported obesity Italy is among the best nations, second (with 9.4%) women after Korea (2.3%) (the OECD average is 16.68 per cent) and third for men (11.8 per cent) after Korea (4.4%) Chile (7.9%) (the OECD average is 16.78 percent).

On average for both sexes it ranks third with 10.6% (again after Korea and Chile), while the declared "big obese" are in the United States (31%, rising to 40% with obesity measured), Iceland (26.6%) Hungary (21.2 percent), compared with an OECD average of 16.72 percent (24 percent with obesity measured).
