These days, developed countries women receive educations and earn salaries and at par with men. The fact that women are no longer socially or economically dependent on men has radically altered the Gen Y and Z. A woman can now choose to remain single, marrying only when a man adds value to her life or when she desires to have children. The direct effect of being a developed nation is the declining birth rates.
The reproduction rate that keeps a population stable for developed countries is 2.1, yet nearly half the world's population has birth rates lower than that. America has a total fertility rate of 2.0. Based on a statistical data in 2010, 31.4 million American live alone. To them, living alone allows them to pursue individual freedom, exert personal control and go through self-realization, these people will have fewer children. Western European countries have lower fertility rates, below 2.1. Germany 1.4, Holland 1.8, Belgium 1.8, Spain and Italy 1.4, Sweden 1.9, Ireland 2.1 and UK 1.9. These rates are derived from non-European immigrant parents.
Go no further. Lets have a look at our neighbour, Singapore. Singapore's experience no different from those developed countries. Their birth rate have been steadily declining. The fertility rate of the Chinese is the lowest at 1.08 (2011), Indian 1.09 and Malays 1.64. In other words best to describe, successive generation of Chinese Singaporean will halve in the next 18 to 20 years. Having babies of course a personal decision, but for a nation's population that decision carries considerable consequences. The decision of their women and their ability to be high income earners have altered social behaviour and led to marriage much later in their life. When women put off having children until their mid-30', they have fewer children.
Singapore in 2011, seven working adults supported one retiree. By 2030, 2.3 working adults will have to support one retiree. There is 340,000 people over the age of 65 with 2.36 million people between 15 to 64. By 2030, Singapore will have 900,000 over the age of 65 with only 2.04 million working adults between 15 and 64. Many women prefer to be single. It's grave problem that 44.2% men and 31% women age 30 and 34 single. Marriage rate in 2011 falls across groups of below 30 with greatest drop in the 25 to 29 years old group. Hence, the number of newborn decrease tremendously.
Singapore government now struggling to alter this phenomena. More encouraging scheme was introduced to encourage parents to have three or four babies or perhaps more.
