Population aging and its consequences
Dragos Maria Andra
Ageing population is a worldwide pattern. The population is getting older and this has social, political and economic impact on all societies,as fertility rates have fallen to very low levels and persons tend to live longer.In 2012 population reach 7 bilion,562 milions were 65 years old and over while in 2015,the older population rose by 55 million.
With the post World War II baby boom generation in United States and Europe joining the older positions in recent years and with the accelerated growth of older populations in Asia and Latin America, the next 10 years will observe an increase of about 236 million people aged 65 and older throughout the world.The term "Baby Boom" is used to identify a huge increase in births following World War II. Baby boomers are those people born worldwide between 1946 and 1964, the time frame most commonly used to define them. The first baby boomers reached the standard retirement age of 65 in 2011. There are about 76 million boomers in the U.S., representing about 29 percent of the population.In Britain, the boomer generation is known as "the bulge."
Population aging, while due mainly to lower fertility, also reflects a human success story of amplified longevity. Today, living to age 70 or age 80 is no longer a rarity in many parts of the world. However, increasing longevity has led to new challenges: How many years can older people expect to live in good health? What are the chronic diseases that they may have to deal with? How long can they live independently? How many of them are still working? Will they have sufficient economic resources to last their lifetimes? Can they afford health care costs? The world is facing these and many more questions as population aging continues.Older people (over 65) are supported by working population and they’re dependent on them and this has economic and social impacts, which can affect a country’s future development.

When the birth rate of a country declines to the point where it is lower than the death rate it entry into Stage 5 of the Demographic Transition Model (DTM)- theoretically.The negative population growth rate is not an immediate effect however. Based on demographic momentum, in which total population growth increases even while birth rates decline, it will take a generation or two before a negative population growth rate is observed.
In Stage 1, both birth rates and death rates are high.
In Stage 2, mortality, especially infant and child mortality, declines rapidly while fertility lags and remains high.
In Stage 3 a fertility transition occurs as fertility declines rapidly, accompanied by continued yet slower declines in infant and child mortality, but accelerated mortality decline at older ages and the population starts growing.
In Stage 4,...
