Located entirely within the municipality of Surrey, Surrey Central had its southern boundary along the Serpentine River and its northern boundary fronting the Surrey North electoral district. Using the last available census (1991), it was estimated to have 112,682 people during the 1997 election, which was higher than the average electoral district. When the data from the 1996 census became available Surrey Central was estimated to be the most populous electoral district in Canada, at 149,468 people. People with a South Asian ethnicity made up about a quarter of the electoral district's population and it included the largest concentration of Indo-Canadians in any electoral district in Canada.
