Example resident address (home), census tract (white outline), egocentric neighborhood (black outline), self-defined neighborhood boundary points (1–4), resulting self-defined neighborhood following the road network (gray area), self-reported grocery store location, and the distance from this location to the nearest boundary of each neighborhood delineation (black lines). This is a purely illustrative example and does not represent data for an actual respondent in order to ensure anonymity.
