While limited in dense suburban housing, Millendon features large residential properties, often with spacious gardens, lifestyle blocks, and small-scale farms. The area attracts those seeking a quieter, country-inspired lifestyle within reach of urban amenities. The population is relatively small compared to more suburban areas of Perth, contributing to its peaceful and rural atmosphere, with census data generally reporting a population numbering in the hundreds rather than thousands.
