This paper presents a comparative typological analysis of ten communities where Air Force Bases were located. Data for the analysis were secured from questionnaires, field interviewers with local dominants, census data, and historical records. Utilizing pattern analysis, the ten communities were found to cluster into four “types.” Materials from the interviews with local leaders and “top” base officers were analyzed, and distinctive types of interaction processes between the base and its host community were revealed. Four types of interaction processes were identified for the ten communities. Thus, two typologies, one of the process and one based on structure were developed. In all cases the bases in any given structural type also fell into the same process type.
