DAC datasets

• Question 1: Are they remotely available?
• Source files at UCLA Data Access Center (the “DAC”)
• Secure site at UCLA Center for Health Policy Research
• All CHIS data items except direct identifiers available, including:
• Detailed demographics
• Small geographic identifiers
• Highly sensitive items (e.g., sexual orientation, ER visits due to mental health)
• On-site or remote access available
• More than 80 researchers have used or are using the DAC
• Question 2: Are the data structure the same as the PUF or AskCHIS?

• AskCHIS uses design information in the inference while PUF is supported by the replicate weights.
