Figure 3: Incidence of Blood Lead Levels ≥ 10 mcg/dL Among Children Under Age Six Years; 1998 to 2007 Blood Lead Test Data, New York State Excluding New York City

Figure 3 shows the total number and rate of children under age six years newly identified with BLLs ≥ 10 mcg/dL by year of testing. In 2007, a total of 1,901 children were newly identified with BLLs ≥ 10 mcg/dL, corresponding to an incidence rate of 9.2 per 1,000 children tested for blood lead in that year (0.92 percent of children tested).

Trend data show the dramatic improvement since 1998 in reducing both the number and rate of children identified with incident BLLs ≥ 10 mcg/dL. The total number of children newly identified with BLLs ≥ 10 mcg/dL declined 63.4 percent between 1998 and 2007, from 5,198 children in 1998 to 1,901 children in 2007. The incidence rate declined 68.3 percent over the same period, from 29.0 per 1,000 children tested in 1998 to 9.2 per 1,000 children tested in 2007.

These data are broken out by specific blood lead level categories in Figures 4 - 9.

  1. Incidence Rate: Total number of children under age six years identified for the first time with confirmed BLLs ≥ 10 mcg/dL divided by the total number of children under age six that had lead tests in that given year, multiplied by 1,000.
