Abstract: An ongoing question in studies of residential segregation is how best to capture the complexity evident in multi-ethnic cities and in cities with growing immigrant populations. One of the difficult issues is to capture local complexity and to visualize how that complexity changes over space. Using a new mathematical framework based on trajectories of aggregated spatial units, one gets a flexible method for capturing segregation as a multiscalar phenomenon. Thus, the key to the analysis is studying how far, in terms of distribution distances for example, any neighborhood is from the city wide measure of ethnicity. We use these methods to investigate social mixing in the Southern California metropolitan area. We find that these methods provide excellent measures of the patterns of mixing across urban space and that the trajectories reveal the spatial speed at which the process of convergence takes place. From the studies of Southern California and Los Angeles, we show how relative isolation generates ``hot spots'' of slow convergence to region wide averages. The advance in measuring segregation with the trajectory convergence analysis is that we have both numerical measures of the level of segregation and a visual picture of the outcomes of social distance.
