The sampling frames for the Primary Sampling Unit (PSU) and Ultimate Sampling Unit (USU) were the list of Census blocks and none respectively. The sample size was 75000 households or other units. The overall response rate for the survey was 93 percent. Errors/biases were minimized by using an updated sampling frame.

Enumeration procedure: Enumeration uses a panel design in which each reporting unit is enumerated more than once. The sample is divided into 3 representative sub-samples, some of which are replaced with new ones during the lifetime of the panel. Each sub-sample remains in the panel for 24 months. The panel has an expected lifetime of 2 years, and each reporting household/unit is enumerated 3 times in total. If a reporting household/unit drops out from the panel, it is abandonned. If changes occur in composition of the reporting household/unit during the lifetime of the panel, then it continues in the panel. No action is taken to select a smaller set of reporting units for more detailed questioning.
