Social factors in street tree planning focus on how people perceive and interact with trees—their preferences for appearance, cultural values, and the street’s overall look and feel. The option describing aesthetics captures this aspect best because visual appeal and harmony with the streetscape drive choices about species, form, and placement to gain public acceptance and satisfaction.

Economic considerations like costs of establishment are about finances rather than public perception, while edaphic soil and humidity are environmental factors that affect tree growth and survival rather than social attitudes.
