We broke our neighborhood down to its most simplistic terms: How many we are, by sex and race, our collective education level, our household income and other data drawn from Census data (2010 being the most recent year available) and the American Community Study of 2015. To find these numbers, we pulled from the five zip codes to which the Preston Hollow/North Dallas Advocate covers: 75220, 75225, 75229 and 75230.
