the prestige and performance of particular school districts, as well as access to careers in high-tech firms, have in general played significant parts in influencing the settlement patterns of taiwanese americans. areas with high concentrations of taiwanese immigrants include the san gabriel valley (greater los angeles), santa clara valley (cupertino, san jose), east bay (dublin, pleasanton, el cerrito, oakland), los angeles/orange county border communities (cerritos/artesia), and irvine in central orange county. outside of california, there are also major taiwanese concentrations in flushing, long island city, and forest hills within new york city, jersey city and hoboken in nearby new jersey, rockville, maryland (northwest of washington, d.c.), sugar land, texas (near houston), plano, texas (near dallas), bellevue, washington (and adjacent areas) (part of the greater seattle area's "eastside" communities), and chandler, arizona. additionally, the northeastern suburbs of the atlanta, georgia area has also received a significant influx of taiwanese immigrant residents. the taiwanese population was formerly dominant in monterey park, california. the san gabriel valley has a larger population of "mainland chinese" from taiwan, essentially outnumbering native taiwanese. since the middle 1980s through the 1990s, however, large numbers of more affluent taiwanese americans began moving out to more upscale neighborhoods like cupertino, san mateo, palo alto, fremont, newark, and pleasanton in the bay area; san marino, arcadia, south pasadena, and temple city in western san gabriel valley; hacienda heights, rowland heights, walnut, and diamond bar in eastern san gabriel valley; with immigrants from the people's republic of china and cantonese and teochew (mostly from vietnam) taking their place in monterey park, as well as alhambra.
