Research Question (Clear, unambiguous) "My research questions are which schools have had the greatest levels of socioeconomic integration in the last ten years (from 2006 to 2016)? What impact has shifts in local housing patterns had on the socioeconomic integration of nearby schools (elementary, middle, and high school)?"  Well, pick one?  These are, of course, basic empirical questions.
Relevant Literature Perhaps you could be a bit more specific as to what the "relevant literature" would be.
Causal Interpretations (clear, all parts defined, mechanisms, controls, plausible) To the degree that school attendance is defined by geographical boundaries, then, of course, changes in residential racial composition of families with school age children necessarily alters student racial composition, within the limits of people exiting to private schools.  This is causal in a way that does not require research (except to show how much or how people elude the requirements).  If the catchment area is altered by rezoning that changes the racial composition, the exact same logic applies.  When students are allowed to apply beyond these areas, as with entering high school, then, of course, it becomes, in part, a different process resembling the sorting of college applications in its cause and effects.
Data (variables, sample, comparison) The data sound fine, although integrating the two sources could prove time consuming.
Research Value Well, there is no apparent attempt to examine causal alternatives.  This is more an effort to discover just what things look like as a result of the known causal processes interacting with unknown (or unexamined) redistribution of families by race and economic categories and rearrangement of boundaries.  Empirical accuracy is a worthy goal.  In this case, you might also be able to assess which of the contending causal processes happens to be having a greater effect.  
Overall This seems a solid empirical project, driven by local policy concerns.
