Like many surrounding neighborhoods, the growth of Los Angeles-proper and the expansion of corresponding freeways resulted in a transition to working-class housing and industrial developments throughout the 20th century.

Over half of the population of Diamond Bar was identified as being of Asian descent, per the most recently available census data. Those of Latine descent account for another 1/5th of residents.

Diamond Bar originated with Ricardo Vejar, who was given one of the aforementioned individual Mexican land grants in 1842. A few years later, upon his death, the territory began to be divided into several different sub-properties, the town (roughly) being one of them.

The acreage was initially utilized for cattle ranching, and a popular branding insignia is responsible for the name of Diamond Bar. In the 1950s, Transamerica used the area for a corporate planned community, but this dissolved by the mid-1980s. The town was officially incorporated in the aftermath in 1989.
