Cities with City Health Dashboard data currently in Chattadata

The dataset combines migration data from Redfin for 132 U.S. cities (2019-2021) with health information from NYU Langone Health's City Health Dashboard.

This indicator provides information about lead exposure risk for census tracts in Los Angeles County based on self-reported housing and poverty data. Using methods implemented by New York University for the City Health Dashboard, a lead risk index score ranging from 1 to 10 was assigned to each census tract with available data, with a score of 1 indicating the lowest risk and a score of 10 indicating the highest risk for lead exposure.Lead is a heavy metal that has negative impacts on nearly every system in the body, particularly the brain, kidneys, and blood. Although lead paint was phased out in the 1970s, legacy lead paint and dust remain primary sources of lead exposure in the US. Literature on lead poisoning consistently finds two factors to be correlated with lead exposure risk: the age of houses (which predicts the likelihood of lead paint) and poverty. While all people can be affected by lead, young children and pregnant persons are the most vulnerable. Irreversible neurodevelopment effects, including decreased IQ, shortened attention span, and reduced fine motor skills, occur at even low levels of lead exposure. At high levels, anemia, high blood pressure, seizures, and death can occur. There is no known safe level of lead exposure for children.For more information about the Community Health Profiles Data Initiative, please see the initiative homepage.

This indicator provides information about the percentage of housing stock at risk for containing lead for census tracts in Los Angeles County based on self-reported data. Using methods implemented by New York University for the City Health Dashboard, housing units were categorized as follows: pre-1940, 1940-1959, 1960-1979, 1980-1999, and 2000-2023, with each category weighted according to the level of risk.Even though lead-based paint was banned in 1978, approximately 29 million housing units in the US still have lead paint hazards, including deteriorated paint and lead-contaminated dust. Studies show that the proportion of children with elevated blood lead levels declines with housing age, and housing age is widely considered the most established risk factor for lead poisoning.
