The characteristics of segregation in a micro scale and the particularities of medium‐size cities in the distribution of different socioeconomic groups throughout the urban tissue are still poorly explored. This paper investigates the relationship between the configurational characteristics of 10 Brazilian cities with population between 200,000 and 350,000 and the distribution of socioeconomic groups over the urban fabric. More specifically, it (a) checks if the main routes of the urban grid pass through the cities' economically disadvantaged areas; b) quantifies the relationships between accessible and segregated areas and the social groups to which they correspond; and (c) checks whether there is a relationship between income inequality and mean integration measures for the cities as a whole. We test the hypothesis that higher income population prefer to locate themselves in areas with higher integration (closer to other areas of the city, thus achieving high accessibility) but medium to lower choice areas (away from main through passages, thus balancing accessibility with lower quantities of strangers passing by, noise and other types of nuisances).The methodology involves visual analysis of segregation maps and the comparison of integration and choice measures for census tracts with higher and lower mean income (10 percent of the census tracts on both extremes). Results showed that, for medium‐sized cities, the dominant pattern of segregation is characterized by lower income groups located at the outskirts and higher income groups located in highly integrated and more central areas. However, other spatial strategies are employed to serve the desire of high‐income groups to distant themselves from low‐income areas, such as grid discontinuities and separation by undeveloped areas and/or main thoroughfares.
