Definition: An abortion is the termination of a pregnancy by the removal or expulsion of an embryo or fetus from the uterus, resulting in or caused by its death. An abortion can occur spontaneously due to complications during pregnancy or can be induced.
Abortion as a term most commonly - and in the statistics presented here - refers to the induced abortion of a human pregnancy, while spontaneous abortions are usually termed miscarriages.
"This year" refers to the period from Jan 1 at 00:00 up to now.
The data on abortions displayed on the Worldometer's counter is based on the latest estimates on worldwide abortions published by various sources, including the World Health Organization (WHO). According to WHO, every year in the world there are around 73 million induced abortions. This corresponds to approximately 200,000 abortions per day.
In the USA, where nearly 30% of pregnancies are unintended and 40% of these are terminated by abortion, there are between 1,500 to 2,500 abortions per day. Nearly 20% of all pregnancies in the USA (excluding miscarriages) end in abortion. Guttmacher Institute reports 930,160 abortions performed in 2020 in the United States, with a rate of 14.4 per 1,000 women. CDC reports 629,898 abortions in 2019, with a rate of 11.4 abortions per 1,000 women (excludes CA, MD, NH).
