The data in this file come from a survey of adult residents in the Commonwealth of Northern Mariana Islands (CNMI). The survey was conducted for a random stratified sample of households on the islands of Saipan, Tinian, and Rota from August 2016 to April 2017. These data were collected to record baseline human dimensions information and socioeconomic characteristics of CNMI’s coral reef adjacent populations such as human use patterns, management support/opposition, and knowledge, attitudes, and perceptions of coral reefs/coral reef management. These baseline data are being used as a starting point for socioeconomic monitoring of CNMI’s coral reefs. Data were collected through the telephone random digit dial survey method and the face to face interview method, and the total sample size for this survey was 722 with a response rate of 20%.
