[3] The district was first formed ahead of the 1943 Philippine legislative election following the ratification of the Second Philippine Republic constitution which called for a unicameral legislature composed of delegates from all provinces and chartered cities in the country.

[4] Bacolod, a chartered city since 1938, elected Francisco Zulueta to the National Assembly, who was joined by then-mayor Alfredo C. Yulo as an appointed second delegate.

[3] In the unicameral Batasang Pambansa that replaced the House, Bacolod was not entitled to its own separate representation despite being a highly-urbanized city.

Instead, it formed part of the multi-member Region VI's at-large district for the interim parliament from 1978 to 1984 and Negros Occidental's at-large district in the regular parliament from 1984 to 1986.

[6] The district is currently represented in the 18th Congress by Greg G. Gasataya of the Nationalist People's Coalition (NPC).
