Among women aged 45-64 years, average incidence rates were 58% higher in Marin County than in the rest of the SFBA and were 72% higher than in other urban California counties.
Rates of later-stage (stage III/stage IV) disease were not significantly different in Marin County (15 cases per 100,000; 95% CI, 12-19) as compared with those in other areas (SFBA: 13 cases per 100,000; 95% CI, 12-14; other urban California counties: 14 cases per 100,000; 95% CI, 13-14).
Prehn and West, using 1990 census data, calculated breast cancer incidence rates for aggregations of census block groups matched to Marin County on characteristics associated with higher breast cancer risk (percentage white population, urban status, average parity, median household income, percentage of persons with a college degree, percentage of persons with a working-class occupation, and percentage of households living below the poverty line), and found rates in the matched areas to be comparable with those in Marin County [ 4 ] . In another study using interview-based information, higher breast cancer incidence rates among white women in the SFBA were also fully explained by the distribution of parity, age at first birth, months of breast-feeding, age at menarche, and age at menopause [ 5 ] . Other previous analyses of nationwide variation in breast cancer incidence and mortality found most of it attributable to the distribution of known breast cancer risk factors [ 15 16 ] . It thus seems likely that a substantial part of the excess incidence observed in Marin County is explained by a higher concentration of women with a higher breast cancer risk profile.
Using population estimates obtained from the California Department of Finance [ 9 ] , we calculated incidence and mortality rates for the individual years 1990-1999 as well as for the 5-year period 1995-1999 for three geographic areas: Marin County, the rest of the SFBA (Alameda, Contra Costa, San Francisco, San Mateo, and Santa Clara counties), and other urban counties in California.
Nearly all of the excess in overall rates was for early-stage (stage I/stage II) disease, for which Marin County rates (175 cases per 100,000; 95% CI, 165-187) were 31% higher than those for the rest of the SFBA (134 cases per 100,000; 95% CI, 131-136) and were 48% higher than those for other urban California counties (119 cases per 100,000; 95% CI, 117-120).
