This map reflects the recruitment completion status by state, as of November 29, 2023. States that are colored dark blue are complete. States colored light blue to red are not complete. If your residence(s) is/are in a state that is not dark blue, we could use your help!

We are still continuing to randomly sample new residences in states where we have not reached our target number of completed surveys, but you can volunteer to complete a survey. To volunteer to complete a survey and/or to be sure that your residence(s) is/are included in the NSTARR database, please complete this form. The study team will send you a survey link and password to take the survey if your residence qualifies.
