Table 3 shows the result of a special analysis to identify those ZIP codes with the highest annual incidence of BLLs ≥ 10 mcg/dL among children under age six years in 2005. This analysis was conducted to identify the specific geographic areas of highest priority for targeting of public health prevention efforts to achieve the goal of eliminating childhood lead poisoning by 2010. To identify these high incidence ZIP codes, all incident BLL results (including New York City) were sorted and ranked by ZIP code2. ZIP codes falling within the top decile (at or above the 90th percentile) were designated as high incidence ZIP codes.
Through this analysis, 68 high incidence ZIP codes were identified across the state, including 46 ZIP codes within the five boroughs of New York City and 22 ZIP codes within ten counties outside of New York City. Collectively, these 68 ZIP codes account for 54.5% of all EBLLs statewide in 2005, and for 39.1% of all EBLLs statewide excluding New York City. In addition, these ZIP codes account for 58.3% of all EBLLs within the ten upstate counties in which they are located.
Table 3 lists the high incidence ZIP codes identified by county. These are also displayed graphically on Map 6 (New York City data not shown). In addition, Table 3 notes with an asterisk (*) those counties that were also identified as high incidence through county-level analysis (see Map 4). High incidence ZIP codes that fall within these high incidence counties are especially high priority targets for public health lead elimination efforts. Maps 7a - 7g provide more detailed graphic depictions of these target areas.
|County||ZIP Code1||City||Number Newly Identified ≥ 10 mcg/dL||Percent Contributed by ZIP code to Statewide Total||Percent Contributed by ZIP code to Statewide Total, excluding NYC|
|Statewide excluding NYC||2,283||46.3||100.0|
|ZIP code total||2,586||52.5||--|
|ZIP code total excluding NYC||893||--||39.1|
- ZIP codes within the top decile (at or above the 90th percentile) were designated as high incidence. New York City ZIP codes are not shown.
- Each incident EBLL result was assigned to the ZIP code associated with the child's address. BLL results without a meaningful residential address or no address recorded were excluded from the analysis.
