Proponents of school choice argue that schools of choice build stronger parent communities. Using data from the National Household Education Surveys Program, a nationally-representitive cross-section of U.S. households, I examine the empirical evidence for this claim. To account for the difficulties in identifying causal effects in cross-sectional observational data, I estimate a model that includes the parent's unobserved propensity to both participate in school activities and to choose a public or private school other than their geographically assigned public school.
