Life expectancy at birth increased by almost 10 years since 1970, says a report published by Organisation for Economic Co-operation and Development (OECD).

Nearly all OECD and emerging countries have experienced large gains in life expectancy over the past 40 years. Life expectancy at birth in Turkey, Korea and Mexico has increased by twenty years or more over the period 1970-2010.

Higher national income is generally associated with higher life expectancy at birth, although the relationship is less pronounced at higher levels of national income.

Japan, Spain, Switzerland, Italy and France are ranked on the top place, as the average life expectancy for 2013 exceeds 82 years, whereas Japan reaches 83.4 years and Spain 83.2 years.

Greece is in 14th place on the list 81.4 years of life of expectancy.

Indonesia, Russia, India and South Africa are ranked at the lowest places ranging from 70.9 to 56.8 years.
