Community Analysis Reports and the Community Analysis Trend Reports document an effort by the War Relocation Authority (established in 1942 to assist persons of Japanese ancestry who had been evacuated from the west coast by military order in the interests of national security) to obtain an understanding of the social background of the evacuees and their reactions to conditions in the relocation centers. The monthly reports to the Washington headquarters of WRA document general studies of center populations, and report on specific problems or concerns of their respective centers. These were accompanied in many instances by reports, interviews, questionnaires, and other writings by evacuees.

The records reproduced in the microfilm publication are from "Records of the War Relocation Authority," Record Group 210.
