In 2022, there were around 613 thousand legal abortions in the United States. The number of legal abortions in the United States has decreased significantly since the early 1990’s. This number will probably continue to decrease in the coming years since many states have severely limited or completely banned abortion after the overturning of Roe v. Wade by the Supreme Court in 2022. The states with the highest abortion rates In 2022, the rate of legal abortions per live births in the United States was 19.9 per 100. In comparison, in 1990 there were 34.4 abortions per 100 live births. The states with the highest rates of abortion per live births are New Mexico, Illinois, and Florida. In Florida, there were around 37 abortions per 100 live births in 2022. Florida had the highest total number of abortions that year, followed by New York and Illinois. Missouri and South Dakota had the lowest number of abortions in 2022. Out-of-state abortions Critics of the Supreme Court decision to overturn Roe v. Wade argue that while those who can afford it may be able to travel to other states for an abortion if their state bans the procedure, poorer residents will have no such choice. Even before the overturning of Roe v. Wade, out-of-state residents already accounted for a high share of abortions in certain states. In 2022, 69 percent of abortions in Kansas were performed on out-of-state residents, while out-of-state residents accounted for around 62 percent of abortions in New Mexico. Illinois had the highest total number of abortions performed on out-of-state residents that year, with around 16,849 procedures.

In 1900, the fertility rate in the region of present-day South Korea was six children per woman, meaning that the average woman born in South Korea in that year could expect to have six children over the course of their reproductive years. This number began to fluctuate in the 1930s, when the Japanese administration (the Korean peninsula had been annexed by Japan in 1910) promoted fertility as part of the war effort, before fertility dropped below 5.2 births per woman in the aftermath of the war. It then increased above 6.3 in the 1950s due to the devastation and mass-displacement caused by the Korean War. As stability returned to the region, South Korea's fertility rate would fall sharply throughout the remainder of the century, as modernization, urbanization, and the implementation of family planning programs would see fertility fall to just over 1.5 children per woman by 1990.

Sex-selective abortion and gender ratios Abortion was illegal in South Korea between 1953 and 2020, although it was permitted in some cases from 1973 onward. Despite this, these laws were rarely enforced, and sex-selective abortion became widespread following advancements in ultrasound technology. In many Asian societies, it was often preferred to have male children as they were viewed as being better long-term providers for their parents and they would carry on the family name. In South Korea in the early 1990s, the practice of sex-selective abortion became so widespread that the gender ratio at birth was 114 males for every 100 females (reportedly as high as 125 in some cities), compared to the historical and natural average of approximately 105 males per 100 females. The government then prohibited doctors from revealing the gender of unborn babies to the parents in 1987, and introduced more severe penalties in 1994, in an attempt to revert this trend. The gender imbalance then reduced in the following decades, and has been at 106 males per 100 females since the 2010s (roughly the natural average). Abortion rights in South Korea were expanded in 2021.

Lowest in the world? Despite government initiatives aimed at increasing fertility, including financial incentives, South Korea's fertility rate has continued to fall in recent years, and today is at around half of replacement level. In 2020, it is estimated that the average woman born in South Korea will have just over one child over the course of their reproductive years. Some critics cite economic factors, such as high education and housing costs, for the reason that young couples are postponing marriage and having families; today, South Korea has the lowest adolescent fertility rate, and the lowest overall fertility rate in the Asia Pacific region. Due to the current trajectory of South Korea's fertility rate, in January 2021, it was announced that the South Korean population experienced a natural decline for the first time in it's history.
