The 2004 joint annual Conference of the National Society of Black Physicists (NSBP) and the National Society of Hispanic Physicists (NSHP) was held in Washington, DC during the weekend of February 18th-21st, 2004. This conference, held jointly for the first time this year, provided the over 300 African-American and Hispanic-American physics students with the unique opportunity to meet and network with working minority physicists. Also in attendance were graduate school and corporate recruiters, administrators, faculty members, and various professional society representatives. As in previous years, the Conference organizers contracted with the Statistical Research Center of the American Institute of Physics to conduct an evaluative study of the meeting. The questionnaire instrument was designed by the Statistical Research Center's staff and the Conference organizers, and structured to allow comparison with the responses of participants from the previous year. Conference participants were asked to provide information on their academic background as well as demographic characteristics. They were also asked about their physics research experience, career goals, their participation in various nationally-sponsored internships and support programs, challenges faced in their academic pursuits, and ratings of various aspects of their Conference experience. The 6-page questionnaire was distributed at the Conference. Around 312 students attended the Conference and were given the survey to complete. Responses were collected on the last night of the Conference, with 147 (47%) returning completed questionnaires. (Contains 7 figures and 8 tables.)
