To cope with population change, the constituency boundary between Wan Chai District and Eastern District was changed in the new year's day of 2016 (effective on voting in 2019 Hong Kong local elections). As a result, the Victoria Park and Tin Hau constituencies became a part of Wan Chai District starting from that day. As a consequence, the whole of Causeway Bay is now part of Wan Chai District. But the easternmost parts of the area, such as Oil Street, and the western side of Tin Hau Temple Road, remain in the Eastern District.
