Healthy Life Expectancy - Overview

We want to travel to our favorite destinations, achieve success in careers, buy or build a home at a special place and do a whole lot of things before we run out of time.

All this we want to do while expecting to live longer. But what does longer life means?

Life Expectancy

Longevity is the term often used for ‘long life’ or ‘great duration of life. It also stands as a synonym for ‘life expectancy’ in terms of demographic definition. 

According to World Health Organization, life expectancy means “the average number of years a person is expected to live on the basis of the current mortality rates and prevalence distribution of health states in a population”.

While there isn’t any exact tool to measure your life expectancy since longevity depends on several factors, yet healthy life expectancy calculator is an apparatus that one can rely upon as it is backed up by science.

Life Expectancy Calculator

Researchers around the world support life expectancy calculator as it analyzes various factors such as gender, age, how much exercise we are doing, how much we are earning, education and chronic diseases such as diabetes. 

It also digs deeper into our lifestyle such as smoking, sleep durations, accidents, alcohol intake, etc. to compute the approx. length of life.

While many of us won’t believe the estimates of the calculator, yet it spins our head and compels us to think of changing our lifestyle. If you are really serious about your life expectancy, give a shot to this calculator.

Factors responsible for longevity

We have crossed a long length of evolution and the longevity or life expectancy has certainly increased over the past century due to several factors. Here we will mention some factors that affect life expectancy.


It’s a well-established fact that women live longer than men on an average. In India, life expectancy at birth has shown good progress since last 7 decades with the increment of 27 years of a citizen. 

The average life expectancy at birth now stands at 68.3 years. Women and men in India can now expect to live 69.9 years and 66.9 years respectively.

Socio-economic status

The socio-economic status plays a crucial role in overall life expectancy. Among several things, poor socio-economic status can lead to inaccessibility to proper healthcare and healthy diet.


Life expectancy is highly affected by healthcare system in a country. Though the healthcare system in India has improved in past decades, especially in terms of infant mortality rate which has been reduced by 76 percent over 55 years, yet there is a long way to go.

India spends just 1.3 percent of the total GDP which is way low compared to BRICS nations. Where South Africa spends 8.8 percent of the total GDP on healthcare, Brazil and Russia spends 8.3 percent and 7.1 percent respectively.

Much to surprise, even SAARC nations such as Afghanistan (8.2 percent), Nepal (5.8 percent) and Maldives (13.7 percent) are way ahead of India in terms of healthcare expenditure.


Education is directly linked to socio-economic status and both work in harmony in improving the lifestyle. According to United Nations Educational, Scientific and Cultural Organization, India has made good progress in terms of literacy amid the period 1980-2015.

Seven out of 10 Indians above the age of 15 years can read and write a short story about their everyday life. This is 30 percent increment as compared to 1980s when only 4 out of 10 Indians were literate. 

Higher education level is also linked to the lower level of obesity, smoking, tobacco usage, etc. which greatly hinders longevity.


The most crucial aspect is the way you live your life. The lifestyle factors which affect mortality include tobacco use, unhealthy dietary habits, inadequate exercise, excessive use of alcohol, marital status, risky behavior, workplace and motor vehicle safety among others. 

But today, the most crucial one that poses challenges to almost every populated nation is the obesity.

  1. China with 15.3 million and India with 14.4 million have the largest number of obese children in the world.
  2. According to a study published in Paediatric Obesity, by the year 2025, India will be home to 17 million obese children.
  3. Another comprehensive health survey of the country shows that 31.3 percent of urban women are obese while obesity in rural women stands at 15 percent.
