Rowland Heights, California

Rowland Heights is an unincorporated community and census designated place (CDP) in and below the Puente Hills in the San Gabriel Valley, in Los Angeles County, California, United States. The population was 48,231 at the 2020 census. Rowland Heights is in the Los Angeles metropolitan area and represented by the County of Los Angeles (County Board of Supervisors) and is the second largest census designated place in Los Angeles County by area, behind Topanga, and the county's fifth largest CDP by population. The area has a high Taiwanese population and was known as "Little Taipei" in the 1980s and 1990s, when it saw an influx of wealthy immigrants from Taiwan.

A number of corporations, such as Newegg, FedEx, DIRECTV, and Fashion Nova, as well as other technology and import and export businesses, are located in neighboring City of Industry. Many business owners and employees reside in Rowland Heights as well as neighboring Hacienda Heights and Walnut due to their proximity.

The Mexican land grant Rancho La Puente was granted by Governor Juan B. Alvarado to John Rowland in April 1842, totaling about 18,000 acres (7,284 ha). Three years later, Governor Pio Pico amended the grant, enlarging it to nearly 49,000 acres (19,830 ha) and adding William Workman as a co-owner. In 1868, after they received their federal land patent the prior year, Rowland and Workman divided Rancho La Puente, with Workman largely taking the western and central portions and Rowland the northern, southern and eastern sections, including what became most of Rowland Heights. The east section of Rowland Heights, between Nogales Street and Brea Canyon Road, falls within Rancho Rincon de la Brea. The ranch of Rowland's grandson, John A. Rowland III was behind the 99 Ranch Market near the corner of Gale Avenue and Nogales Street and the Rowland family owns part of that property today, leasing most of it for commercial use.

Rowland Heights grew significantly during the 1990s. Originally built on a pig farm that covered much of modern-day Rowland Heights, the Rowland Homestead was mostly orange groves until the eastward sprawl from Los Angeles spawned working-class communities and affordable housing developments then formed. As the 60 freeway was extended beyond the western boundary, the community continued growth equal to that of most communities in Southern California. Development next to the freeway, zoned for industrial investment, eventually helped to support the housing developments that continue well into the 21st century.

Since the 1990s, there has been a significant demographic shift as many upper-class immigrants from Taiwan, China, and South Korea have settled in the hillside homes of Rowland Heights (and in neighboring regions such as Hacienda Heights, Walnut, and Diamond Bar). Also, Rowland Heights has also attracted immigrants from mainland China because the area is advertised in China as having high-end homes and convenient shopping centers. Many work at or own businesses in the nearby City of Industry. Additionally, Latinos have maintained a long-standing presence in the lower sections. The city has developed an eclectic suburban "Chinatown", "Little Tokyo", and "Koreatown", mostly in the form of upscale strip malls. There are several large Asian product supermarkets in the area.

Once predominantly Anglo and Hispanic since inception in 1842, this area has gradually become one of the Chinese centers in the greater Los Angeles beginning in the 1990s. Originally formed by the stream of business expansions from Monterey Park (now a heavily mainland Chinese enclave), Rowland Heights has become an area largely populated by Taiwanese. Local Taiwanese refer to Rowland Heights as "Little Taipei", due to its high concentration of Taiwanese restaurants and businesses. It has become the center for Chinese commercial and cultural activity in the southeastern region of the San Gabriel Valley. While Rowland Heights and adjacent areas are still predominantly Waishengren (mainland Chinese refugees who retreated to Taiwan in 1949), in recent years many mainland Chinese emigres have also been increasingly purchasing homes and starting small businesses in the area. Some eateries of Taiwanese cuisine are operated by mainland Chinese. Additionally, there are restaurants geared toward the young and affluent Chinese population.

Possibly owing to Rowland Heights as evolving into the cultural center for the Chinese diaspora, many 49er Taiwanese (multi-generational natives of the island formerly known as Formosa), with a growing number of mainland Chinese now live in the area. In 1992, a connection (Harbor Boulevard) from northern Orange County (mostly to the city of La Habra) opened in Rowland Heights, making Fullerton Road among the heavily traversed roads in the region.

In March 2012, a 750,000 pounds (340 t), two-story granite rock was parked on Pathfinder Road as it journeyed from Riverside County to the Los Angeles County Museum of Art as part of Michael Heizer’s Levitated Mass exhibition.
