Westminster began as a Presbyterian temperance colony founded by the Reverend Lemuel P. Webber in the early 1870s — a settlement where alcohol was banned from the start — and only 225 people lived there by 1874.

The city incorporated on March 27, 1957, growing out of a plan to merge Westminster, Barber City and Midway City into a single municipality called Tri-City.

The 2020 census counted 90,911 residents in Westminster, living in about 28,150 households with a large average household size of about 3.2 people.

After the fall of Saigon in 1975, tens of thousands of Vietnamese refugees settled in Westminster, drawn by its affordable housing, and built the community now known as Little Saigon along Bolsa Avenue.

In the 2010 census, 36,058 Westminster residents — 40.2 percent of the city — were Vietnamese American, the highest concentration of Vietnamese Americans of any city in the United States.

Westminster is unofficially known as the 'capital' of overseas Vietnamese, and its Little Saigon is regarded as the largest Vietnamese enclave outside Vietnam.

Some 500 Vietnamese businesses opened in the Bolsa Avenue area during the 1980s alone, and on weekends the crowds drawn to Little Saigon can triple the number of people in the city.
