Answer:
By the year 2050, the population of individuals that are sixty years and older will increase by more than 1 billion. The total population of the world at a given time provides only a small amount of information. A more useful measurement is the growth rate, which measures how fast the population is growing. The world’s population growth rate was highest in the early 1960s at a rate of 2.2 percent. Since then, it has been declining. But this rate isn’t the same around the world. In some countries, the number of deaths is greater than the number of births. This shows a negative growth rate. In other countries, the number of births is greater than the number of deaths. This shows a positive growth rate. What the world’s population looks like has also changed in the modern age. Life expectancy has increased over time. People today live longer than people did one hundred years ago. For example, in 1881, the life expectancy in India was only 25 years. Today, the life expectancy in India is 60 years. This is fairly close to the life expectancy of 63 years in the developing world. The country with the world’s highest life expectancy is Monaco, where people live to an average age of 89.4 years. Life expectancy is directly related to a nation’s health and economy. The increase in life expectancy has led to an increase in the population of people age 60 and older. About 20 percent of the population in the developed world is 60 years or older. That’s about 240 million people. By 2050, one in three people will be over 60 years old. This trend will have economic impacts on many countries, depending on how many young people live there. World wide, there have been products of better medicalization of the modern world which advances the life expectancy of those places. And due to the significant aging population, then the total number of individuals that are over 60 most likely will be over 1 billion by 2050.
