PEER REVIEWED
The top 2 maps depict the number of study participants residing in each census tract. A greater number of participants resided in north, south, and northeast Philadelphia, as well as the south and central New Jersey regions. The bottom 2 maps illustrate the ethnic density of neighborhoods within Philadelphia County and new Jersey, by census tract and illustrates that there are distinct neighborhoods where Asians are concentrated within. There is a greater proportion of Asian residents within south and north areas of Philadelphia, as well as in central and north New Jersey.

Interaction effects of high ethnic density and low ethnic density groups for barrier score on colorectal cancer (CRC) screening behavior. Three perceived barriers to CRC screening were assessed, each totaling 1 point, and summed to produce the barrier score (range, 1–3). Error bars represent 95% CIs.
| Ethnic Density | Barrier Score, 95% CI | |||
|---|---|---|---|---|
| 0 | 1 | 2 | 3 | |
| Low | 0.37 (0.33–0.42) | 0.31 (0.27–0.35) | 0.25 (0.18–0.31) | 0.19 (0.11–0.28) |
| High | 0.35 (0.27–0.42) | 0.18 (0.12–0.25) | 0.08 (0.02–0.15) | 0.03 (–0.01 to 0.08) |
