The tremendous decline has been observed by experts in the fertility rate of women. Rate today is declined to 2.44 birth per woman, a 0.4% decline from the last year (macrotrend.net).

With the decline in the fertility rate, population aging is a big challenge throughout the world, but on the other hand, it is enhancing economic growth by increasing per capita income. As an outgrowth of the falling fertility rate according to demographers, every state could have a reduction in the population by the end of this century.

A few researchers forecasted the result as a baby boom where the others consider it as a baby bust. More or less 116 million children were born during the covid’19 pandemic (UNICEF). Lockdown led to the suspension of people getting their hands on contraceptive pills, a primary cause leading to a baby boom.

However, reproductive disadvantages are obvious, causing an evolutionary problem. We are now breaking the norm, where gay relations are becoming legalized. Expected reproduction, in this case, will obviously lessen. Clearly, couples of the same sex cannot have unplanned pregnancies. As the acceptance of this sexual diversity, it is expected to reduce the rate of childbirth. The homosexual genes increase the risk of homosexuality in kids, hence, gay couples are more likely to adopt children. Whereas, heterosexual couples have a better success rate in reproduction increasing the population multiple folds.
