As of 2022, individuals with disabilities make up 5.2 percent of South Korea's population. Using basic arithmetic, this percentage corresponds to approximately 15 seats in the country’s 300-member unicameral parliament.

In reality, just four seats are currently occupied by individuals with disabilities, constituting only 1.3 percent.

The first person with a disability to win a parliamentary seat as a constituency representative was Lee Chul-yong. In 1988, on the ticket of the liberal Party for Peace and Democracy, he won the election in a Seoul constituency and joined the 13th National Assembly. Before him, the Assembly building in Yeouido, Seoul, did not even have a single ramp.

Since Lee's groundbreaking entry into the legislature, South Korea has witnessed a succession of lawmakers with disabilities, totaling 17 as of January 2024.

The share of parliament seats held by persons with disabilities has fluctuated within a narrow range, with multiple instances of 0 percent -- the most recent being the 20th parliament (2016-2020) -- to a peak of 1.67 percent in the 18th parliament (2008-2012).

Of the total 17 representatives with disabilities, all but four were elected through the proportional representation system.

Among them, the most prominent figure in mainstream politics now is arguably the five-term Rep. Lee Sang-min, who uses a wheelchair. Recently, he garnered significant media attention by bolting out of the opposition Democratic Party and joining the ruling People Power Party.

Shim Jae-chul, a former five-term lawmaker who walks with a cane, attained the highest office among politicians with disabilities in Korean politics by serving as the vice speaker of The National Assembly during its previous 20th session.
