# Seongbuk A

Seongbuk A (Korean: 성북구 갑) is a constituency of the National Assembly of South Korea. The constituency consists of portions of Seongbuk District, Seoul. As of 2020, 202,294 eligible voters were registered in the constituency. The constituency was created in 1988 from the Seongbuk constituency.

## History

Throughout its history, Seongbuk A more often elected members of centre-left, liberal parties to represent the constituency. The centre-left Democratic Party's Lee Chul, who was elected as an independent, was the first member to represent Seongbuk A in the National Assembly. He was re-elected in the 1992 South Korean legislative election, but lost to Yoo Jae-geon of the liberal National Congress for New Politics in the 1996 legislative election. Yoo went on to win re-election in 2000 and 2004. The conservative Grand National Party's Jung Tae-geun won the seat in the 2008 legislative election, marking the first time a conservative party won the constituency. However, he was defeated by the liberal Democratic United Party's You Seung-hee in the subsequent legislative election held in 2012. You Seung-hee won re-election in 2016 as the liberal Democratic Party's candidate, defeating Jung once again. Kim Young-bae, the former Mayor of Seongbuk, was nominated as the Democratic Party's candidate for Seongbuk A in the 2020 legislative election, having defeated incumbent You Seung-hee in the party's primary for the constituency. Kim went on to win the election, defeating Han Sang-hak of the United Future Party by more than 24 points.

## Boundaries

The constituency encompasses the neighborhoods of Gireum 1-dong, Donam 2-dong, Anam-dong, Bomun-dong, Jeongneung-dong, Seongbuk-dong, Samseon-dong, and Dongseon-dong.
