Responding to the reflections on A Portrait of Los Angeles County, Measure of America codirectors Kristen Lewis and Sarah Burd-Sharps first provide an overview of how they applied the Human Development Index to Los Angeles, including the categorizing of different neighborhoods from Glittering to Precarious. They then engage with key issues of ethnicity, incarceration, and the ways different parts of LA County are interrelated and affect each other—all issues that emerge from the reflections by Jennifer Lee, Pedro Noguera, and Kelly Lytle Hernandez and Terry Allen.
