Notes: Standard errors clustered on census tract are in brackets. Outcome is an indicator for whether the child lived in a house with a certificate as of the date of the first blood test for the child. Certificates in tract is the number of certificates in the census tract of the child’s home (at the first lead test of the child). In columns 1 and 2, “certificates in tract” refers to the total number of certificates (DOH and HRC, combined). In column 3, we estimate the effects of the two different certificate types (DOH and HRC) separately.
