WHERE IS THE DIMSUM?

• Clusters in San Gabriel Valley• 158,000 Chinese in SGV

in 1990• Strong correlation between

dim sum locations and high percentage of Asians

• Clustering of both in San Gabriel Valley

METHODOLOGY. Geocoded all dim sum restaurants on Yelp. Analyzed race in 2mile buffers around all locations

WEIGHTING

ASIAN RACE x 1 SPEAK L ANGUAGE x 2 BORN IN ASIA x 3

METHODOLOGY. To understand the geographical phenomenon of Asian clusters, I looked at how the Asian race, population born in Asian and % who speak Asian languages clustered in LA

There were clear clusters around Rosmead, Covina and Rancho Palos Verde. For the purposes of this study, I selected the cluster of tracts around Rosmead and Monterey Park for analysis.

HOW ASIAN IS IT?METHODOLOGY. “Asian Tracts” were selected by rasterizing and classifying the features of “Asian Race”, “Born in Asia” and “Speaking Asian Language”. Asian Tracts were calculated by weighing each features as described in the previous slide.

• 78% of the people who work in Rosemead and Monterey Park live in the “Asiaburb” (PUMS data 1990)– LA average for living in the same

Public Use Microdata Area is 23%• “AsiaBurb” is an integrated work and

living space • Rosemead and Monterey Park are the

key points

ENTREPRENEURS IN ROSEMEADMETHODOLOGY. Distance from each tracts to one of the hubs was calculated by converting the tract into a point and then measuring the distance to the centroid of Rosemead of Monterey Park

Strong correlation between entrepreneurship and tracts near Rosemead

Should further study the dynamic between Rosemead and Monterey Park



GOTTA SPEAK THE LANGUAGEMETHODOLOGY. Distance from each tracts to one of the hubs was calculated by converting the tract into a point and then measuring the distance to the centroid of Rosemead of Monterey Park

Strong external connection to AsiaAverage of 42% speak Asian LanguageHeaviest language use is slightly outside THE hub of Rosemead and Monterey Park



CONCLUSIONS• Asianburbs replicate some features of old

networks– Places where Asians can speak their

mother tongues– Conduct business through their own

networks– Keep close ties to countries of origin– Places where they can feel at home– Not springboards to assimilation but

communities…and that mean a lot of dimsum places
