Outage duration versus the maximum number of affected customers for counties with low and high social vulnerability [a) socioeconomic vulnerability, b) household composition vulnerability, c) minority vulnerability, and d) housing type vulnerability] with local polynomial regression. Horizontal axis: log scale of the maximum number of affected customers in a county. Vertical axis: log scale of the outage duration. Blue: high social vulnerability counties. Red: low social vulnerability counties. The blue and red curves: local polynomial regression curves that show the relationship between the number of affected customers and the outage duration.
