Children Under 6 yrs with Elevated Blood Lead Levels (BLL)
These data are an indicator of children younger that 6 years of age tested in NYC in a given year with blood lead levels of 5 mcg/dL or greater. About the Data All NYC children are required to be tested for lead poisoning at around age 1 and age 2, and to be screened for risk of lead poisoning, and tested if at risk, up until age 6. These data are an indicator of children younger that 6 years of age tested in NYC in a given year with blood lead levels of 5 mcg/dL or greater. In 2012, CDC established that a blood lead level of 5 mcg/dL is the reference level for exposure to lead in children. This level is used to identify children who have blood lead levels higher than most children's levels. The reference level is determined by measuring the NHANES blood lead distribution in US children ages 1 to 5 years, and is reviewed every 4 years.

The publisher's promise
How the agency that publishes this data says it keeps the data current.
OverdueNo automatic refresh
- Automatic refresh
No scheduled refresh runs for this dataset. A refresh you ask for on this page runs anyway.
The publisher set a regular schedule for this dataset but has not updated it for far longer than that schedule, so the automatic queue skips it. An hourly triage lifts this fence once the publisher updates it again, which takes up to about 7 hours 15 minutes.

Columns
Each source column, with the name and type we use to store it.
0 of 19 columns carry a concept; 19 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.

children_under_6_years_with_10 | Children under 6 years with elevated blood lead levels (BLL) Rate BLL>=10 µg/dL per 1,000 tested | Number of children less than 6 years old tested in a given year with blood lead levels of 10 mcg/dL or greater, divided by the number of children less than 6 years old who were tested for lead poisoning in a given year; expressed as cases per 1,000 tested. The numbers in this table include all children tested within a given calendar year, regardless of whether they were tested in previous years with the same or different blood lead levels. While children can receive more than one test during the calendar year, children are only counted once using the highest confirmed blood lead level during the calendar year. If the child does not have a confirmed test in a given year, the child’s blood lead level is based on the highest capillary or unknown test type. This measure differs from the rate of children newly identified with blood lead levels at or above 10 mcg/dL reported by the Health Department in other publications. <a href="http://a816-dohbesp.nyc.gov/IndicatorPublic/EPHTPDF/Childhood_Lead_Exposure_Definitions_June_2016.pdf" target="_blank">Read more </a>about different measures used by the Health Department for surveillance of childhood lead poisoning. | Not bound | Number | children_under_6_years_with_10 | numeric | — | |
