National Network of State Polls

National Network of State Polls (NNSP) is a confederation of organizations that conduct state-level surveys. The network promotes the collection and use of state survey data.

The NNSP archive of state polls is the largest available collection of state-level data. It is part of the data archive of the Odum Institute for Research in Social Science. The archive contains nearly 70,000 items from more than 660 studies, contributed by 44 survey organizations in 25 states. More than 600,000 respondents contributed to the surveys. Archived data are included in the Odum Institute's data catalog. For more information about these studies, contact Jonathan Crabtree, 919-428-6112.
