TABLE 4—

Variation (on Logit Scale) in Mortality Between Census Tracts (CTs) by Race/Ethnicity, Before and After Taking Into Account CT-Level Poverty: Massachusetts, 1989–1991

	White	Black	Other
Before taking account of poverty	0.08	0.52	0.52
After taking account of poverty	0.07	0.19	0.12

Note. Estimates for Whites relate to the CT-level random parameter estimate associated with σ²_υ0 in Models 2 and 3 (see Table 3 ▶). Estimates for Blacks were not estimated directly but were based on the sum of the random parameter variance related to Whites (σ²_υ0), the differential variance associated with Blacks (σ²_υ1), and 2 times the covariance between these 2 variances (σ_υ0υ1 ) in Models 2 and 3. Estimates for “others” were not estimated directly but were based on the sum of the random parameter variance related to Whites (σ²_υ0) the differential variance associated with others (σ²_υ2) and 2 times the covariance between these 2 variances (σ_υ0υ2) in Models 2 and 3.
