Malays make up the majority of voters in Lembah Pantai electorate at 52% followed by the Chinese at 26%, Indians at 21%. The total number of eligible voters is 56,650.
One of the more popular areas which come under Lembah Pantai constituency is Bangsar, a popular upmarket residential and entertainment area. Most of the residents here are well to do and less reliant on the government. When it comes to voting, their trend is based on what appeals to the mind, which are issues such as corruption and transparency.
Pantai Dalam is a residential area located south of Bangsar. There are many smaller residential areas that form the larger residential area of Pantai Dalam, including:
- Pantai Hillpark
- Kampung Pantai
- PPR Sri Pantai
- Desa Aman 1 & 2
- Pantai Murni
- Taman Bukit Angkasa
- Pantai Baru
- Kampung Pasir
- Taman Pantai Dalam
- Taman Pantai Indah
- PPR Kampung Limau
- Taman Dato'
Pantai Dalam is a perfect watershed between two groups of urban Malays: the affluent and the working class. The former live mainly in gleaming, whitewashed condominiums like the Andalusia Condominium in Pantai Hillpark, or in luxury bungalows in Kampung Pantai and Pantai Halt.
For the working class, the luxury apartments located further uphill are perhaps symbols of what one can aspire to. Most of them live in the low-cost apartments.
Most of the area’s residents are:
- blue-collar workers living in flats that had been sold to them under the People's Housing Project when they were resettled from their squatter homes several years ago.
- students of the University of Malaya.
- police officers/personnels, mainly in Desa Aman 1 & 2.
The Member of Parliament for the Lembah Pantai parliamentary constituency is Nurul Izzah Anwar from Parti Keadilan Rakyat, who won the seat in the 2008 Malaysian general election from the incumbent Shahrizat Abdul Jalil representing the Barisan Nasional ruling coalition. Shahrizat had held the seat since 1995. The swing towards the less experienced Parti Keadilan Rakyat candidate was mainly due to the general dislike of Abdullah Ahmad Badawi's weak leadership at the time.
The constituency is represented in the Malaysian Cabinet. Shahrizat Abdul Jalil who was the former MP is the current Minister of Women, Family and Community Development, while Senator Datuk Raja Nong Chik Zainal Abidin, Head of Lembah Pantai's UMNO Division is the Minister of the Federal Territories and Urban Well-being.
