Description |
Data Source |
State and Local Data Systems |
Purpose |
This data set will be used to calculate incidence measures for emergency department (ED) visits related to asthma, unintentional CO poisoning, heat stress illness, and chronic obstructive pulmonary disease as described in the Part 1 package, for use on the national public portal. |
Geographic Level |
The smallest geographic unit to be represented in this data set is the census tract. |
