District Information

District Profile from Politics in America

Although the bulk of its population lives in Orange County, the Republican-leaning 42nd is centered around the suburbs where Orange, Los Angeles and San Bernardino counties come together east of Los Angeles proper. From there, the 42nd has a long arm that stretches southeast and then southwest farther into Orange County to Mission Viejo and Rancho Santa Margarita. A chunk of eastern Anaheim also falls within the district's borders.

Chino and Chino Hills in San Bernardino County have an agricultural heritage, but the economic influence of dairy production is waning due to residential development and the increasing presence of manufacturing and service sectors. Retail and residential property growth has been volatile in the San Bernardino portions of the district, but home construction continues.

Diamond Bar and Rowland Heights (shared with the 38th) in Los Angeles County have large Asian populations. Hispanics and Asians also live in the northern Orange County cities of Brea (which has experienced downturns in the commercial and financial sectors), La Habra and Placentia (shared with the 40th), although this segment of Orange County is predominately white-collar and white. Overall, the district is mostly middle and upper class and dominated by residential communities. Many residents work in technology firms and commute to Los Angeles or Irvine (which is located in the 48th).

Conservatism persists here, and the district gave GOP candidate Meg Whitman her highest percentage statewide (59 percent) in the 2010 gubernatorial election, but the influx of Hispanic and Asian residents in the past decade may swing the political lean.
